The Dave Matthews Band Summer Tour Lights Up with Video and Moving Heads

“Don’t Drink the Water”? please, Dave Matthews Band’s Summer Tour’s lighting was good to the very last drop. Lighting and Sound America did a great article on DMB’s summer tour and now I have so much to say about it, all good things of course. I have so much to say about it because I was there earlier this summer (and unfortunately did not bring a camera!) to enjoy the music and the lighting action. DMB’s concert was an amazing display of LED video and moving head technologies. The video walls worked well at the DMB show, as it does at most arena and stadium venues, because they do away with the space between the stage and some of the satellite seating areas. According to LSA, DMB’s set up featured 30 LED video walls at the front of the stage which projected all of the guitar, violin, and drum action. Although the video walls dominated the front of the stage, it was by no means too much. The walls were balanced by an impressive array of moving head spot and wash units that filled the stage with impressive saturated colors while animating the music with dancing beams.

The DMB Summer Tour featured other lighting effects, including strobes, which added to the ambiance, the dancing, and the crush of fans singing along in the audience.
The entire concert, as all concerts are today, controlled perfectly using a series of controllers and back up controllers in case one was to fail. According to LSA, the concert’s designers heavily utilized cues and scenes to keep the show feeling tight, as well as allowing the band’s performance and the lighting to remain synced up night after night. The effect of the synced up lighting and performance resulted in me, and the rest of the audience included, I’m sure, wanting to stay for a while, a long while more. Well, I guess that does it for this article. And will I tell you what song Dave closed with? What would you say? No way, you’ll have to see Dave and the band for yourself.

In the Spotlight#5: Mercury Vapor Lamps

Today’s article will be on mercury vapor lamps. In the past we have received many questions regarding these HID lamps so I will provide you with an introduction to them and give you the necessary information to help you decide whether it is the correct lamp for your needs. The mercury vapor lamp is generally used in outdoor and industrial settings including street lighting, industrial hi-bay lighting, parking lots, and other flood lighting applications. The mercury vapor lamp is one of the easiest HID lamps to understand. It operates as all HID lamps do, an initial pulse of current ionizes the gas in the bulb which allows it to be sufficiently excited by continued electrical current, exciting the gas inside (mercury in this case) and produces light, or photons. The excitation of mercury takes place within the lamp's arc tube, specifically between the electrodes within the arc tube. Metal halide lamps and high pressure sodium lamps use a mixture of gasses and metals, but mercury vapor lamps uses, you guessed it, mercury vapor exclusively. The different metal and gas combinations of HID lamps give them their characteristic light qualities. Mercury vapor lamps are characterized by moderately good color rendering and bright light. One of the main reasons for mercury vapor lamps’ better color rendering is that many of them come with phosphor coatings which markedly improves color rendering.

It is no wonder, given its moderately good color rendering and various applications, that mercury vapor lamps come in a wide range of wattages, from 100w or less to 1,000w. Mercury vapor lamps typically come in medium screw base or mogul screw base sizes, unless they are short arc lamps, which require an M4 base or another type of base.

That is about all you need to know for familiarizing yourself with mercury vapor lamps. Of course we could've gotten far more technical, and if you want to know more, or know something in greater detail I would be happy to field your questions. Also, call 1-877-622-0897 if any other issues that may crop up. If you are ready to start looking for your own mercury vapor lamp then check out what we have to offer, you won’t be disappointed.

In the Spot Light #4: Low Pressure Versus High Pressure Sodium Lamps

In the next installment of my ‘In the Spotlight Series’, I will look at low pressure and high pressure sodium bulbs and how they differ. These two lamps have been a source of confusion for some our customers, so let’s get started clearing the air regarding these two lamps. Low pressure sodium (LPS) and high pressure sodium (HPS) bulbs belong to the HID lamp family, which means that they produce light by exciting gasses and vaporized metals with electrical current to sufficiently excite them and produce light. The composition of LPS and HPS lamps is somewhat similar, they both contain a noble gas and solid sodium. HPS lamps may contain additional metals and have a slightly different construction than LPS lamps, but the specifics of these differences are not necessary for the purposes of this article. What really sets LPS and HPS lamps apart is the qualities of their light and the size of their lamps. LPS lamps are known for their very yellow or orange light, these lamps are most commonly used in certain commercial and residential outdoor applications and street lighting. LPS bulbs are widely used because they are very efficient and have a very high luminous efficacy of around 200w/lm. One of the reasons for LPS bulbs’ efficiency is that nearly all of the light produced is easily visible by the human eye, close to zero ultraviolet or infrared light is produced. LPS lamps can be very large, reaching beyond 3.5ft in length. It is for this reason that sometimes streetlights or highway light fixtures are very large.

HPS lamps are used most often in outdoor applications such as street lamps, parking lots, and flood lighting and horticultural applications, where color rendering is not a priority. HPS lamps are efficient as far as HID lamps go, but do not have the quite the luminous efficacy of LPS lamps. Though HPS lamps are not as efficient as LPS lamps, they have excellent light spans with life hour ratings of 16,000 – 24,000 hours and are also typically smaller in size. The higher atmospheric pressure of the HPS lamps allows its contents to be assembled in a smaller lamp, and thus allowing the lamp to be installed in smaller fixtures, making it easier and less cumbersome to install and use. HPS lamps’ color temperatures are typically a yellowish-white light.

BulbAmerica has a great selection of both LPS and HPS bulbs to satisfy your lighting needs. Check out what we have to offer. As always, do not hesitate to leave a comment or question on the blog or give us a call at 1-877-622-0897.

The World's Largest LED Screen is on Display in Shanghai

The 2010 World Expo in Shanghai, which began in May, is a multi-month event for the nations of the world to congregate and share with each other their cultures, peoples, and spirit. The architectural and artistic contributions of the nations present were not the only thing on display. Beginning this year’s world Expo featured a display of the wonders of LED technology with a light and fireworks show with the largest LED screen ever created at its center. The Shanghai LED screen was 9,500m, which is equivalent to nearly 105 football fields. The screen demonstrated many of the unique merits of working with LEDs. For one, because LEDs emit light from tiny bulbs and are clustered together, they can be formed into virtually any shape. This is especially useful for LED panels where they may need to be mounted in oddly shaped ceiling or wall spaces. The screen was also amazingly colorful, highlighting LEDs’ ability to rapidly change color and create bright, well rendered color. The durability of LEDs made them an obvious choice for the World Expo. The screen was situated on the banks of the Huangpu River in the center of Shanghai, so the weather and environment were unpredictable.

I probably sing the praises of LEDs too often on this blog but applications like the screen in Shangai beautifully display the technology’s versatility. From high resolution and low resolution panel displays to LED bulbs, consumer products, LED PAR cans, and DJ effects, LEDs are changing the lighting game. Though we can’t offer you a 105 football field long LED screen, we can offer nearly all other LED products and at great prices too, so check out what we have to offer!

In the Spotlight #3: Reflector Bulbs

This article is the third article in my ‘In the Spotlight’ series of articles, which aims to address common concerns to many of our customers. Upon reflecting upon reflector bulbs, I realize that they can be confusing as there are a number of them, and not all of them are clearly differentiated. With that preamble out of the way, let’s get started with reflector bulbs. If you are familiar with light bulbs you have may seen the designations, ‘R’, ‘BR’,’PAR', or ’ER’. As you may have guessed, the ‘R’ in all of these designations stands for reflector. An ‘R’ bulb, take an R30 for example, features a reflector that concentrates and directs the beam of light, making it excellent for flood or narrow flood lighting, retail lighting, outdoor lighting, and other applications. Bulge reflector (BR) reflector bulbs are not very different. What makes a BR bulb different from an R bulb is its bulge. The bulge houses an additional bulbous reflector surface which is supposed to collect more light and feature improved luminous efficacy. Parabolic aluminized reflector (PAR) lamps are another reflector lamp that produces an ovular (hence parabolic) soft-edged light. PAR light is typically less diffuse than R and BR lamps and for this reason it is popular in theatrical lighting applications and flood lighting. Elliptical reflectors (ER) feature a half-ellipse shaped lens which has the unique property of forming the beam up to 2.5 inches from the front of the lens due to the lens’ two focal points. ER bulbs are ideal for recessed lighting.

When thinking about reflector, one must keep in mind that often when speaking of reflector bulbs we are talking about bulbs with built in reflectors, like a PAR bulb, which features a seamlessly constructed bulb-beam-lens combination. This is not always the case. You should remember that this is not always the case. DYS lamps for example, are often used with reflectors however they do not typically come with them built in. Certain fixtures, like Ellipsoidals for example, feature a reflector that surrounds the lamp inside the fixture and concentrates the beam. This is really a caveat and beyond the intention of this article, but it doesn’t hurt to be aware of the other ways reflectors are used.

Hopefully this article has been of some use to you and has given you a sense of order in the chaotic universe of reflector bulbs. As always, post any questions or call us at 1-877-622-0897 for help. Don’t forget to check out all of the Rs, BRs, PARs, and other reflector bulbs we offer. They are great and your lighting deserves to be too!

In the Spotlight #2: Metal Halide HID Lamps

This article is the second in my ‘In the Spotlight’ series. This article will illuminate metal halide high intensity discharge (HID) bulbs. We have received a lot of questions over the phone and online about what exactly these bulbs are and how they differ from other HIDs, so I will tackle these questions and more in this article. Metal halide lamps are typically used in commercial, theatrical, projection, industrial, and outdoor floodlight applications. Metal halides are a great choice where good color rendering, bright light, and durable lamps are needed. With that in mind, you are probably wondering what the ‘metal halide,’ in metal halide lamps means. To answer this question it is useful to know a little bit about how a metal halide HID lamp works. In a metal halide, electricity ionizes the starting gas (typically argon) and the mercury vapor and vaporizes the metallic material inside the arc tube. The electricity continues to excite the mercury vapor and the vaporized metals inside the tube, producing visible visible light, and reaching full brightness usually under less than a minute. The metals inside are of course the metal halides which allude to a family of metals including sodium, tin, scandium and others. Different metals are chosen by manufacturers to yield different light color temperatures and properties.

Out of all the HID lamps, metal halide lamps probably come in the most shapes and with the most bases. Metal halide lamps come in the familiar PAR shapes and their various sizes and in less familiar shapes like the T4.5s, the ED28, the BD17, and many others. Metal halide lamps are offered in even more base types than they are shape types. From the ubiquitous medium screw E26 and E27 and their bigger brother the mogul screwbase, to the less common RX7S RSC and others, metal lamps come ready to fix into a multitude of fixtures. This fact hints at the numerous applications of the metal halide lamp and suggests how popular a lighting technology the metal halide really is. Equally suggestive of their diversity of application is the fact that metal halide lamps are available in wattages anywhere between 20w and 24,000w.

There you have it: the metal halide HID. If after reading this you realize that the metal halide lamp is right for your needs, check out our comprehensive metal halide lamp offerings.

In the Spotlight #1: Candlepower Versus Lumens

When looking at the specifications of light bulbs it is very easy to get overwhelmed. There seem to be an extraordinary number of units of measurement for something that seems pretty straight forward, light. One of the two most commonly confused and confounding measurements are candlepower and lumens. We have received numerous customer calls and emails requesting an explanation of how these two units differ, so that will be the focus of this article. Of the two measurements, candlepower is more obscure and I think less fully understood. Candlepower refers to the lighting concentration of a unidirectional light source. In other words, candlepower measures the intensity of light in a single direction. Candlepower, often measured in candelas, are therefore a popular unit of measure for flashlights and focusable light sources like ellipsoidals or spotlights that can project a single narrow beam. A related unit of measurement is center beam candlepower (CBCP) which is a measurement of the intensity of light at the center of a bulb’s light beam.

With the definition of candlepower in mind, let’s move on to lumens. Lumens (lm) are unit of measurement for the measure of total illumination of a given light source. The lumens rating is one of the first specs people look at when comparing bulbs because it does give a fair indication of how bright their light source will be. In particular, measuring the lumens a light source puts out is helpful for lamps produce a diffuse light, like a flood. Measuring lumens is not as useful for highly directional bulbs, like a spot, because you will likely be more concerned with the unidirectional brightness of a bulb rather than its general brightness.

Hopefully the distinction between candlepower and lumens has been made clear in this article and now you can wade through the sea of technical specifications that awaits you. If not, then feel free to post a message or call BulbAmerica toll free at 1-877-622-0897 with any remaining questions you have.

Take a Stand for Great Lighting With a Tripod Stand or Truss System

Many mobile lighting systems utilize stands and portable trusses to erect their lights and illuminate the show or performance. In this article I will go through some of the considerations you should make in choosing the stand or truss system for you, so let’s get started. A lighting stand is typically a tripod stand with a single T-bar support system or a T-bar support system with side bars. Lighting stands are usually between 9ft and 12ft tall and can usually support between 60lbs and 100lbs. Lighting stands are ideal for mobile DJs and small-scale productions because they are lightweight, easily portable, and can be set up by a single person. Pretty much any fixture from pinspots to LED lighting effects can be hung on lighting stands as long as they have some fastening mechanism or clamp to secure it to the T-bar or side bars.

Portable truss systems are also common. Trusses are essentially two light T-bar light stands connected to each other by an I-beam. Portable trusses are usually around 9ft tall and have a span of 10ft. Another common, and handy, option for truss stands are a crank system that eliminates the potentially taxing task of raising your stands. Truss systems are a bit more work than a lighting stand and should probably only be used if you need the additional space to hang your lighting. Portable trusses may also be a good choice if you have light weight speakers you want to mount. Many truss systems will support speakers, but you will want to check your truss’ product specifications before mounting them. Stands and trusses are an essential component of any portable lighting system. You will want to make sure you choose one that is sufficiently durable and can support the weight of your lights.

BulbAmerica has some fantastic stand and truss options, check them out today. For more information or help leave a comment or call 1-877-622-0897

Getting the Most from Your Non-DMX Stage Lighting

Let’s face it, lighting systems can be expensive, complicated, and frustrating to setup and operate. There are probably some of us who probably wish there was a magic wand to orchestrate our lighting without any of the controllers, dimmer packs, terminators, cables, etc. Indeed, there are some situations, low profile traveling bands come to mind, who are either lucky, or unlucky, enough to not have the room in their van nor the money to pack stands, controllers, and cables. Can a band like this still achieve quality lighting without a ‘system’? The answer is yes and in this article, I will detail how you can do this. Though LED PAR cans are great, the most inexpensive and reliable across the entire color spectrum is the standard incandescent PAR cans. It has been well documented that many LED PAR cans struggle to match the brightness and saturated colors of standard PARs as you approach brighter colors and white light. Don’t forget that PAR cans do not need to be hung to work. Using either their yokes, or compact an inexpensive stands like Optima’s PAR can stand, you can place your PAR can at the front of the stage and throw light that way or you can place it behind certain band members and silhouette them for a dramatic and attractive effect. Color gels come in virtually every color imaginable, so you can really customize the mood and atmosphere so it fits your music. Remember, that there is nothing wrong with leaving your lights on full during your whole show, although you may end up burning through lamps and gels, as well as get rather hot on stage. I should remark that if you have some extra cash, LED PARs, like Optima’s or American DJ’s PAR64s and PAR56s are relatively inexpensive and produce far less heat, making your performance a more comfortable one and without the hassle changing bulbs and gels. In addition, LED PARs typically feature a sound operation mode as well as built in programs, making them extremely easy to use.

Another option for non-DMX lighting is LED lighting effects. Many lighting effects units have built in microphones and run according to pre-programmed macros to your music. Nearly all types of LED lighting effects feature this option, so you actually have a fairly large selection of LED effects to choose from. Also, do not forget about fog machine, they do not require DMX controlling, can be mounted anywhere, and enhance any light effect you already have by catching the light in its haze. Aside from fog machines which require a bit more maintenance, LED lighting effects require little maintenance and are extremely durable because they stay cool and burn bright for extremely long periods of time.

In the end, some lights are better than no lights, and a little can go a long way. Don’t forget that many venues may have existing stands or trusses there, so it may be worth investing in your own set of clamps so you can utilize these stands if they exist. As always, make BulbAmerica your number one place for stage lighting, not matter what it is you ultimately need. We are just one click away so get started now!

LEDs on the Seas: LEDs Become a Staple Light Source for Cruise Ships

In back to back issues of Lighting and Sound America there were articles on innovative lighting solutions found illuminating the decks, theaters, and clubs, on the largest and most technologically advanced cruise ships in the world. Behind the lighting successes of Carnival Cruise Lines’ “Dream” boat (July 2010 issue) and Royal Caribbean’s “Oasis of the Seas” boat (August 2010 issue) were many LEDs and moving heads lights, whose durability and versatility guaranteed great lighting and durability in the limited spaces and harsh conditions of the high seas. On both ships, LEDs were used both in modular capacities and fixture capacities within the ships’ theaters and on their dance floors. The Oasis of the Seas featured an array of LEDs on the ceiling of its promenade that had nearly 3,000 LED RGB color changing modules. This design itself was highly versatile, when they were controlled in tandem they served as a low resolution video panel that could create unique ambiance on a large scale during the evening or a special event. On Carnival’s Dream, the dance club was illuminated by different LED fixtures as well as a low resolution LED panel on the ceiling that displayed video. Even the floor in this club was packed with LEDs, beneath the medium resolution floor tiles were color changing LEDs to give the entire space, from floor to ceiling, literally, an exciting feel.

Both Carnival’s Dream and Royal Caribbean’s Oasis of the Seas represent the height of entertainment cruise liners. Both ships feature full indoor and outdoor theaters that are home to the many shows and programs put on during the cruise. The Dream’s outdoor theatre routinely put on eight to twenty minute laser shows that complemented the video being shown on the massive 12ft X 20ft LED video wall. The Dream’s indoor theatre featured a more standard setup with PARs, fresnels, ellipsoidals. One unique problem when it came to operating the lighting system aboard the Dream was that there was a very limited number of lighting technicians available on board, so the lighting systems needed to be simple enough for regular ship staff and performers to operate. The theatrical lighting systems of the Oasis of the Seas were similar to that of the Dream with its mix of standard theatrical fixtures and scattered LED technology.

The versatility of LEDs is certainly one of the main reasons why they are growing increasingly common on cruise ships. Another is there durability, long life spans, and low maintenance costs. BulbAmerica has many LED products to turn any space of yours into a sea of light and color. From LED effects to bulbs, we have what you need, so hope on the LED boat today!

Color Temperature: A Guide for the Perplexed

If you have ever read anything about lighting or purchased a light bulb, you may have very well come in contact with color temperature. Color temperature is an important characteristic of light, and when it comes to choosing a light bulb, it is among the most important considerations. With this in mind, this article will dedicated to color temperature and will provide you with everything you need to know about it. Most basically, color temperature denotes the hue of the light of a given light source. As basic rules of the color temperature scale, warm light is understood up to 2,800K and cool light typically ranges from 3,600K to 4,9000K. In terms of actual hue, warm color will range from yellow to reddish and cool color will range from blue to white. There are other important markers on the color temperature scale that come up and should be noted. For photographers and filmmakers, knowing the color temperature of daylight (5,500K to 6,000K) is an important in attempting to conjure a daylight effect. In lighting especially, you may come across the designation ‘full-spectrum’ light. Full-spectrum light refers to light with a color temperature of 5,000K an up. More specifically, full-spectrum means that the light contains all of the wavelengths from infrared light to ultraviolet, meaning it is the full-spectrum of visible and non-visible light. Full-spectrum light is particularly sought after in greenhouses because it mimics sun light and is excellent for plant growth.

It is helpful to realize that color temperature was first established using incandescent bulbs as its standard of measurement. Therefore, there can be some difficulty in matching fluorescent and other types of light bulbs to standard color temperatures. The color temperatures of light bulbs that are not incandescent sometimes follow correlated color temperature (CCT) rather than color temperature. Don’t be confused, the only difference between the two scales is that CCT is an approximation of regular color temperature: so if you were to compare an incandescent bulb of a certain color temperature and a fluorescent bulb of the same color temperature they may not be identical. CCT is not very widely used, this is especially the case as bulbs like CFLs are more refined and more closely resemble the light of incandescent bulbs. People are sometimes confused about the difference between color temperature and the color rendering index (CRI) as well. CRI denotes the ability of a light source to represent colors as they appear in natural light. The higher the CRI (max 100), the closer the light source is rendering color naturally. What can be somewhat counter intuitive is that a light source can have a color temperature in the daylight range but have an imperfect CRI score, meaning that it doesn’t portray color naturally.

Color temperature is important in creating ambiance whether it is in your, restaurant, retail space, or even on your stage. BulbAmerica stocks light bulbs with a vast range of color temperatures; from the orange lights of low pressure sodium bulbs to the bright whites of LEDs we have them all. Check us out today!

Dimmable CFLs: Are they Really a Bright Idea?

As CFLs storm the lighting world, one sustained criticism of them has been that they cannot dim like incandescent bulbs. This was true when magnetic ballasts were the sole ballast technology for CFLs, but as electronic ballasts have become the standard, dimmable CFLs are now on the market, though not in as large numbers as non-dimmable CFLs. In this article I will take a look at the pros and cons of dimmable CFLs versus dimmable incandescent bulbs and help you decide whether they are worth your money. But first, I think it would be helpful to understand exactly how a dimmer works with an incandescent bulb, and why it is problematic when applied to a CFL. The concept of dimmer is simple, it simply reduces the voltage to the bulb and the bulb’s brightness increases or decreases accordingly. In an incandescent bulb this method of dimming works well because the reduction in voltage simply reduces the amount heat given off and therefore reduces the amount of light as well. This doesn’t work in CFLs because CFLs generate light by exciting a gas, which then yields light. If you cut the amount voltage the CFL receives it will more often than not simply go out because there is not sufficient current to excite the gas.

Today dimmable CFLs are offered by GE, Sun Lite, and Ushio among other manufacturers. Though dimmable CFLs are certainly an innovation, there are certain limitations to these bulbs. First, dimmable CFLs do not usually dim below 10%-20% brightness because the bulb cannot sustain light at that point. Another complaint surrounds the fact dimmable CFLs, and all CFLs for that matter, can take up to a minute to reach full brightness. This means that you cannot dim the bulb until it has reached full luminosity. Lastly and most importantly, there are limitations regarding the type of dimmer you can use with your CFL. As a rule of thumb never use photo cells or timers with any CFL unless you can do so as indicated on the bulb’s packaging. Dimmers are built to work within a certain power range. Dimmers that are designed for primarily incandescent bulbs, and especially older dimmers, will be engineered to work with wattages above 40w, this is too great for dimmable CFLs and could be problematic. More recent dimmers, particularly those released in the 1990s, have a wider wattage range and are therefore most likely compatible with your dimmable CFL. The point is that if possible, you try to find out what type of dimmer you have and what its range is before you dim your dimmable CFL. One final point is that as incandescent bulbs are dimmed their color temperature typically gets warmer and more ambient; this is not really the case with CFLs. The benefits to dimmable CFLs, however, are that they are more efficient and longer lasting and better for the environment. It is also likely that as the incandescent bulb phase-out approaches dimmable CFL technology will only improve, and rapidly. Dimmable CFLs will save you significant amounts of energy and you will not have to change your light bulb as often as if you use incandescent bulbs.

BulbAmerica has a wide selection of dimmable CFLs and regular CFLs in addition to other energy saving lighting products. We also have many, many dimmers. Check out what we have to offer!

Let it Snow with Snow Machines from BulbAmerica

Snow machines are a fantastic lighting effect that rapidly transforms any stage or space into a winter wonderland. There is a blizzard of snow machines to choose from so hopefully this article will help you navigate the options. My favorite snow machines are offered by American DJ and Elation. In particular I like American DJ’s Snow Flurry Snow Machine and Elation’s Silent Snow Effect Machine. American’s DJ’s 2,000 cu. ft./min Snow Flurry has a 2.2L tank capacity to keep you pumping snow for a long time. The Snow Flurry stays cool with its ECO thermal control system so the machine does not overheat; this also ensures the Snow Flurry’s durability. The Snow Flurry also features intelligent pump protection (IPP) so when the machine gets low on fluid, it does not continue to run and damage the machine. The Snow Flurry can be controlled easily with either an included remote control and has adjustable volume level to control the volume of snow produced.

Elation’s Silent Snow is an excellent snow machine option that is great for clubs, theatres, and movie sets. It can produce any amount of snow fall from a light flurry to a steady snow fall. One feature that sets the Silent Snow from American DJ’s snow machine is that the Silent Snow can be controlled via a DMX controller, thus allowing you to integrate it directly into your lighting system. If you do not want to use the Silent Snow with a DMX controller, the Silent Snow comes with a remote control that features a knob that allows you to adjust snow volume as well as an on/off rocker switch. The Silent Snow features the same great construction and performance that all Elation products have, so you know that it is a trustworthy piece of equipment.

BulbAmerica has a great selection of snow machines that will provide your show with a wondrous snow effect. Check out what we have and let it snow!

Israeli Opera Puts Up Nabucco at Masada

In the August issue of Lighting and Sound America Louise Strickland wrote a great article on a production of Giuseppe Verdi’s opera, Nabucco, put on at the foot of Masada Mountain in Israel by the Israeli State Opera. After reading it, I couldn’t resist writing an article about what I thought were its most exciting parts. The whole production was truly amazing and was a definite challenge, but the lighting, in particular, was ground breaking for outdoor theatre lighting. The Israeli Opera’s production of Nabucco was staged on the edge of the Dead Sea, at the lowest point in the world. This remote desert location provided lighting designers with the initial problem of transporting equipment there. Once camels had been deemed the partial solution, design of the show commenced. Lighting designers turned to a whole gamut lighting fixtures. Nabucco was illuminated by 84 moving head spots, 24 moving head washes, 300 PAR cans, and more than 200 ellipsoidals. All of the fixtures that directly illuminated the stage from the trussing had to be particularly powerful and able to throw light a considerable distance because of the height of the trusses from the stage.

The show was dramatically backgrounded by 60 5,000w and 7,000w xenon lamp search lights, to add to the desert ambiance. These search lights were connected to the controllers by either wireless DMX relays or extremely long cables. The show was brought together by a complicated controlling system that involved writing the show on two controllers but only using one to actually perform the cues, etc. This created a safety net in case one of the controllers broke down during the show, there would be another to take its place. This is just a synopsis of the show’s setup, so if you want a more complete breakdown of the show see Strickland’s article.

Though most lighting designer will never put up a light system on the scale that this performance of Nabucco was, on and most certainly not in the Israeli desert, there are some lessons to be learned, especially for the amateur lighting designer. The first is that always remember truss height when choosing fixtures. Secondly, the only way to get a really balanced lighting effect that has excellent coverage is with a mix of different types of fixtures. So, always remain open minded and don’t get too loyal to one technology over another.

CFL Retrofits Hit a Home Run in Home Lighting

Compact fluorescent light (CFLs) bulb technology has now reached a point of significant maturity. Every bulb in the home, from the bulb for the basic lamp in the family room to the vanity lighting around the mirror in the bathroom, that was once the exclusive turf of the standard incandescent now has a CFL retrofit that will save you energy, money, and may even save the environment too. In this article, I will go through the most common household lighting situations and explain the appropriate CFL retrofits in each of them. Lamps are among the most common fixtures in the household so they are a good place to start. Generally there are two shapes of lamps that are most common, the harp lamp and the clamp lamp shade lamp. A lamp with a harp shade features typically features a screw in base and a piece of metal, the harp, which outlines the bulb and secures the shade. I would recommend replacing your incandescent with a twist CFL with a bright light or day light color temperature to get a natural and well diffused light. For lamps with a clamp lamp shade you’ll want to choose an A-shape CFL so the shade can easily clamp with out a problem.

For the bathroom, CFLs are very handy. Vanity strips, the set of light bulbs that often frame mirrors in bathrooms, most often use incandescent globes. There are wide variety of globe CFLs with medium screwbases that can easily replace incandescent globes. A soft white light is generally preferable in this application because the light will naturally be reflected by the bathroom mirror and other reflective bathroom surfaces. Recessed lighting is also common in bathrooms and there are plenty of CFLs to retrofit your incandescent recessed lighting. I would recommend bulge reflector (BR) bulbs for this application. The different sizes that BR CFLs come in guarantee a good fit in your recessed can. Again, soft white light is a good choice in this application but light temperature closer to day light is also sufficient. Throughout the home there are usually numerous mounted ceiling and wall fixtures in the form of track lights, ceiling fixtures, and sconces. For track lighting I would again choose bulge reflectors for a good indoor flood. BR20s through BR40s will be ideal depending on your track lighting fixture; color temperature choice is also flexible in this application and really depends on your taste. For ceiling fixtures I would recommend A-shape or twist bulbs because many ceiling fixtures are originally outfitted with screw in A-shape incandescent bulb and you will want a good fitting bulb. Like track lighting, there is no right color temperature answer in this application, particularly because many ceiling fixtures feature some sort of glass or plastic diffuser that will change the appearance of your light some what. If you can, I would recommend you play around with your color temperature a bit. Ceiling fans also fall within the ceiling fixture category. Your choice of ceiling fan style will change depending upon the fan’s fixture. Usually any bulb from a twist (if an enclosed fixture) or a candelabra or globe (if exposed bulb fixture) will do. Color temperature is flexible with ceiling fans, I happen to like soft white in this application so that is what I could go with to provide an even mellow light. Lastly wall sconces will most likely require a twist or candelabra CFL depending on whether the sconce is enclosed or features an exposed bulb.

Outdoor home lighting can also benefit from CFLs. Use PAR 38 CFLs with a cooler color temperature for outdoor floods and twist, A-shape, or candelabra CFLs for any lantern lighting you may have, any color temperature will do here! Remember that not all CFLs can dim, and many of those that can, cannot dim 100%. BulbAmerica has great deals on all the CFLs mentioned in this article and the best brands too, check us out!

Bubble Trouble: Great Bubble Machines from American DJ and Elation

The bubble machine is one of the most fun and easy to use effects around. Bubble machines can turn a stage or a dance floor into a whimsical and exciting environment with the flip of the switch. In this article I will review two of my favorite bubble machines, American DJ’s Bubble Blast and Elation Professional’s Professional Bubble Machine. The Bubble Blast is a high performance bubble machine conveniently placed on wheels for easy transport. The Bubble Blast produces 100s of bubbles per minute with its primary and secondary fan system which lifts the bubbles into the air and disperses them. The Bubble Blast is as easy to use as it gets. Simply fill the tray with bubble juice and flip the switch on the back of the machine and watch the bulbs fly. The Bubble Blast has a low current draw and solid construction to make it easy on the electric bill and durable, so you won’t have to worry about it being damaged in transit. The Bubble Blast also comes with an option remote control that can control the power, the duration of bubble blasting, and other features.

Elation’s Professional Bubble Machine is another formidable bubble machine option. Unlike the Bubble Blast, Elation’s bubble machine has a yoke on it that allows you to mount it on a truss like you would any other lighting fixture. Elation’s Professional Bubble Machine is powerful; it is able to widely disperse its bubble with its four separate bubble wheels and a trio of fans at the back of the unit. Another feature that sets Elation’s bubble machine apart is that it is also capable of being integrated into a lighting system via its DMX connectivity. This unit also includes a remote control that can serve as a timer and shut the Bubble Machine down when you believe enough bubbles have been created.

BulbAmerica has got the bubble machine for you. Come check us out today!

Moving Heads or Simply Head Aches? On Moving Heads and HOW Lighting

In the summer issue of Worship AVL: Asia, Mark Johnson wrote a nice article on moving heads and house of worship lighting which got me thinking about the topic as well. There are certainly a lot of moving heads to choose today, and if you are designing the lighting for HOW lighting, you’ve got to wonder how these luminaires fit into this specific lighting situation. Moving heads generally provide specific types of light. Spot and wash lights are the most common light beams provided by moving heads and are useful for HOW lighting. A spot beam is a hard edged, narrow beam while a wash provides a soft edged and more diffuse beam. For general lighting and color you may choose a wash moving head while for more specific dramatic moments you may want to accent them using darting beams or something of that sort. These two different light sources do not necessarily mean you need to get different moving heads for each. Some manufacturers, such as Elation, offer hybrid beam moving head such as Elation Design Beam heads, which allow you to adjust your beam type. The choice between a wash and a spot moving head is often more straight forward than choosing between incandescent, LED, and HID moving heads.

LEDs are a compelling option for HOWs because they are incredibly efficient, require little maintenance, and are durable. LEDs however, do suffer some drawbacks. LEDs can produce excellent saturated deeper colors, but struggle to produce sufficiently bright and saturated light for colors approaching white. An additional problem surrounding LEDs has to do with the way they appear when they are lit. When an LED fixture is on its bulbs are not uniformly colored, rather the bulbs are colored individually and mixed to produce the desired color. For LED wash fixtures in particular, this can be an annoying or distracting sight if the luminaire is facing the audience, and thus detract from the service. It is in these capacities that LED moving heads fall short and incandescent and HID are attractive options. Incandescent moving heads are a great option, especially if you are looking for bright white light. Like all incandescent lamps, however, incandescent moving heads suffer from being inefficient. HIDs match the light quality of incandescent bulbs and have much improved efficiency. A HID lamp compared with an incandescent lamp of identical wattage will be brighter and have better luminous efficacy. HID lamps, however, cannot be dimmed because of the manner in which the bulb lights and the extended period of time it takes to achieve full luminosity. HID moving heads therefore use a shutter or douser to dim. This can prove wasteful because HIDs must therefore be on all the time while LEDs and incandescent lamps can be raised and lowered, thus somewhat compromising the efficiency of HID moving lamps.

Don’t forget that many moving heads are decked out with effects like gobos and prism effects that you may or may not want for your HOW service. Remember that either way, whether you want or not you want the built in effects, you are paying for them when you buy a moving head. Lastly, and importantly, moving heads require more DMX channels devoted to them than conventional luminaires. If you don’t have a controller built specifically for intelligent lights, you will find yourself running out of channels very quickly. Therefore remember that installing moving heads may also mean installing a new controller too if you don’t already have one.

BulbAmerica can take care of all your moving head needs and answer any more questions you may have. Check out what moving heads and controllers we have to offer you. And don’t forget to contact us with any questions you may have, we are here to help!

Make Your Event One of a Kind With Apollo's Gobos

Gobos are an integral part of any lighting effect system. Without gobos one would be limited to color and light shows, but with gobos a lighting designer can sculpt the available color and light into patterns and shapes that can capture the ambiance and mood of whatever the situation. As gobos become more common in not only scanners and DJ lighting effects but moving head units and outdoor projectors, the gobo itself has become that much more important. Apollo's outstanding steel and glass gobos are the best in the business and will make your show an unforgettable one.

Apollo offers low resolution and extremely high resolution glass and steel gobos. Apollo’s glass gobos are made from the finest quality borosilicate glass. Glass gobos are capable of producing much higher resolution and detailed images than steel gobos because they do not require bridging, a technique used to connect the separate lines of a design and thus maintain the integrity of the gobo image. Colored designs are also available with glass gobos, thus contributing an additional degree of excitement to your lighting that is not possible with steel gobos. Steel gobos, however are still highly valuable. Apollo’s steel gobos are made from 8mm stainless steel with high nickel and chromium content to ensure durability.
Though Apollo glass gobos are able to withstand high temperatures, steel gobos are generally more durable than glass gobos and are better suited for use in fixtures that generate large quantities of heat such as ellipsoidals and followspots.

Apollo has some very special gobos, in particular their super resolution gobos and multi-color gobos. Apollo’s super resolution gobos depict images in vivid detail, allowing each facet of the image or pattern to be prominent and lively. Multi-colored gobos, which are made from multiple glass dichroic filters fused upon one another, are also an outstanding gobo. Apollo’s multi-colored gobos come in combinations of nearly every design imaginable while still maintaining the integrity of the image being presented.

I could go on and list the possible colors and patterns available but it would simply take too long. Suffice it to say that BulbAmerica stocks 1,758 different gobo patterns and images, so we probably have exactly the gobo you need plus much, much more. Check out what we have to offer, you won’t be disappointed!

LEDs Proves a Viable Lighting Option for Industrial Applications

LED lighting technology is revolutionizing nearly all facets of lighting. There are some who believe LED technology to be overblown and not useful in some applications. One of these applications is in the industrial lighting arena where HIDs and halogens have long reigned. Some people do not believe LEDs can produce substantial diffuse light to adequately illuminate huge spaces like warehouses and that coverage in those areas would likely be spotty. Kompak, a Dutch industrial firm, has recently proved these naysayers wrong by outfitting their entire industrial plant, warehouse, and offices with LED fixtures exclusively. Kompak's warehouse alone spanned approximately 11,500ft and featured nearly 46ft tall ceilings. Their entire warehosue was thoroughly lit by LEDs in large fixtures and cleverly along the pre-existing sprinkler pipes in the ceiling.

Kompak’s energy savings were truly remarkable. Their LED lighting, coupled with motion detectors, allowed the company to save 20,000KWh in electricity. Admittedly Kompak’s LED lighting system was very advanced and featured many custom LED installations not available to the casual consumer. Kompak’s adoption of LEDs however should signal to everyone, however, that lighting virtually any space is possible with LEDs, and that LEDs save astounding amounts of electricity in the short run, and even more astounding amounts of energy and money in the long run. Today LEDs are available in nearly every style that an incandescent bulb is. From candelabra, to globe, to A-shape, and many others, LEDs are becoming an increasingly viable option for light bulbs retrofits for not only incandescent bulbs and halogens, and potentially even CFLs. It is true that LEDs must be made less expensive and technologically refined before they can be widely embraced, however one can clearly see the beginnings of the LED revolution.

Stay on the cutting edge with BulbAmerica’s wide selection of LED bulbs. LEDs are an inexhaustibly bright idea, so check out the LEDs we have to offer for nearly every light application conceivable, you won’t be disappointed!

Elation Beam Design Moving Heads: Moving and Turning Heads Like None Other

As moving head light fixtures become more popular and more ubiquitous, it is harder and harder to choose the one worth your money and that is right for your needs. In this article I will discuss Elation Professional’s Design Beam series of moving heads and what I believe makes them unique and warrants an extra look. So, let’s get started. One feature that sets the Elation Design Beam series is their versatility. The Elation Design Beam 300 and Design Beam 1200 Compact can serve as spot, wash, and beam projectors with their respective 7.5˚ and 6.7˚ beam angles and by opening and closing the head’s frost filter, which changes the hardness of the beam’s edge. This versatility allows you to change the role of your moving heads as well as the look of your lighting effect on the fly. The Design Beam moving heads silently pan 630˚or 540˚ (user selected) and tilt 265˚, allowing for lively performances. The Design Beam and 300 and 1200 Compact also share nearly identical gobo performance with the ability for dynamic gobo prism and rotation effects. The Design Beam 300 and 1200 compact, however, have some distinguishing features that are essential to highlight.

The Design Beam 300 is distinguished from the 1200 Compact foremost by their different lamps. Both moving heads feature Philips MSR HID lamps. The 300 features a 300w MSR that puts out an impressive 33,150lux at 30ft. The 1200 Compact features a 1,200w MSR which produces an extremely bright 107,500lux at 25ft. One of the key differences between the 300 and 1200 compact is obviously their power and luminosity. In selecting between the two you want to consider how much power you have available, how high your trusses will be from the stage, and how much other light is being produced by other fixtures in your system. Another important difference between the two moving heads regards their color capabilities. The Design Beam 300 and 1200 Compact both feature CMY color changing, but the 1200 Compact also offers variable color temperature orange (CTO), in order to correct colors and make their rendering precise.

Elation’s Design Beam 300 and 1200 Compact are high quality and powerful moving heads. What sets the Design Beam heads from other moving heads is their unique frost filter that allows you a great deal of flexibility in deciding how you will use them. In short the Design Beam 300 and 1200 are an outstanding choice for performance spaces of all sizes. BulbAmerica has both moving heads in stock right now, so check it out today!

Pinspots: A Guide for the Perplexed

Pinspots are a common luminaire used in lighting systems big and small. Pinspots can be used for many things, including serving as a spot light and illuminating a disco ball. There is often a bit of latitude in what people call a pinspot, but it is most often associated with a PAR36 can with a 4515lamp that features a very tightly focused beam, usually with a 6˚ to 12˚ beam angle. With the proliferation of LED and moving head technologies, there are pinspots with more features as well as traditional pinspots. Basic pin spots, like Optima’s PAR36 pinspot, features a basic metal can and a 4515 30w halogen lamp. Traditional pin spots accept color gels to give you more versatility in your lighting.

LED pinspots, currently offered by American DJ and Chauvet to name only two, have a much lower energy draw than halogen pin spots and have very long life span. ADJ’s 3w Pinspot LED features a 12˚ beam angle and has a built in rechargeable battery, making the Pinspot Led ideal for portable use. Though you will need to recharge the power supply if you plan on using its battery, you may likely never have to change the LED lamp due its amazing 50,000hr life hour rating. Chauvet also offers a basic and extremely compact 3w pinspot LED with a 9˚ beam angle perfect for the mobile venue or venue with a small lighting system. Chauvet as also upped the pinspot ante by debuting one of the first moving head pin spots, the Pinspot360 5-channel DMX. The Pinspot 360 comes with many of the features a regular moving head does, namely the 540˚ pan/330˚ tilt, built in movement macros accessible via DMX control, and a strobe effect. These features are in addition to the Pinspot 360’s 6˚ (or optional 9˚) beam angle and impressive 15,000lm (6˚ angle @ 1 meter). The Pinspot 360 is obviously ideal if you want a more advanced effect and have a pre-existing system with a controller that can handle intelligent lighting.

With the advent of LEDs and moving heads many fixtures that were at one point simple are now packed with features. This is certainly not to say that basic halogen fixtures are out of date, in fact many lighting designers prefer their simplicity and tried and true luminous power (not to mention that they are most often less expensive than their more advanced counterparts). Regardless of your preference, if you are looking for a pinspot we have got what you need, so be sure make BulbAmerica your pinspot stop and check out what we have to offer.

Griven's Outdoor Color Changers Illuminate Motocross Madness in Mexico

Griven’s outdoor lighting has been used in outdoor applications all across the world. From lighting up the Eiffel Tower to providing fixtures for India’s largest light and water show (see the article on our blog for the full story), Griven has been there and done it all. Recently in Mexico, Griven added one more outdoor lighting notch to their belt by providing outdoor color changers for a motocross trick duel in Mexico City sponsored by Red Bull energy drinks. This stop on the X-Fighters World Tour, as it is called, featured daredevils on dirt bikes going off huge jumps and pulling amazing stunts continuously. The event’s designers knew that they needed lighting to sustain the crowd’s excitement, so they turned to Griven’s outdoor color changers for help. The event featured over 20 MK3 2,500s to illuminate the arena and also facilitate the video broadcasting the event with exceptional color. The event also featured Griven’s Kolor Globe 4000 search lights outside of the stadium to make the event visible from miles away.

The durability and weatherproofing of the Griven color changers and search lights was demonstrated during the event when it began to pour rain. The motocross riders kept riding and the Griven lights kept pace without any degradation of their light quality. The X-Fighters World Tour’s stop in Mexico once again gave Griven occasion to demonstrate its amazing color changers and search lights. BulbAmerica stocks the complete line of Griven’s searchlights and color changers, check them out right now!

Griven's Gobo Projectors Sends Your Logo on the Go

For outdoor projectors and color changers, there is simply no match for Griven. Griven’s gobo projectors, like their outdoor color changers, search lights, and promotional projectors are unmatched in their quality, power, and durability. The Goboclip, Gobostorm, and Gobostorm Plus gobo projectors will project your logo with unmatched brilliance will give your business the attention it deserves. Griven’s Goboclip MK3, Gobostorm, and Gobostorm Plus represent the cream of the gobo projector crop, in this article I will go through some of the key features that make Griven’s gobo projectors great.

The Goboclip comes ready to brave the elements with an IP rating of 65 and a compact and light weight aluminum with a scratch resistant grey coating that allows the Goboclip to remain inconspicuous. The 200w Goboclip uses either a 150w CDM-SA/T 150 metal halide lamp or a 150w HSD 150 metal halide lamp. There are two main differences between these two lamps, the CDM-SA/T150 has an output of 12,900lm and a color temperature 4,200K while the HSD lamp has a slightly lower light output at 12,000lm but has a cooler color temperature at 7,000K. The Goboclip zoom and focus can be adjusted manually, thus allowing you to change the beam angle from anywhere between 19° and 30°. The Goboclip can be controlled in a stand alone mode by using the electronic display at the back of the projector, or it can be used with a DMX controller. The Goboclip is designed so you can be as flexible as you want not only with regard to adjustable beam angle and method of control, but also regarding changing your glass or metal gobos. With the removal of two screws, the entire front of the projector lifts up, allowing you to easily swap in and out gobos and dichroic filters to get your projection perfect.

The 750w Gobostorm is the bigger sibling of the Goboclip. The Gobostorm uses either an MSD or MSR 575w metal halide lamp to ensure that the image being projected can been clearly and at substantial distances. The MSD 575 features a light output of 42,000lm and a color temperature of 6,000K compared to the MSR 575’s 49,000lm output and 7,200K color temperature. The MSD however, has a signficatnly longer life hour rating at 3,000hrs compared to the MSR’s 1,000 life hour rating. The Gobostorm features even more optical variability than the Goboclip with a manually adjustable beam angle of between 10° and 20° via the zoom and focus adjustment. The Gobostorm features the same IP65 rating and die cast aluminum exterior, but also an advanced convection cool system to keep the projector working its best. The Gobostorm shares with the Goboclip its control options as well as convenient and easy access for changing its dichroic filters and gobos. In addition to all of the features of the Gobostorm, the Gobostorm plus has a series on board effects including a mechanical dimmer, a strobe, and special effects (three prisms, five prisms, distortion and frost filters).

The Goboclip and Gobostorm series are among the best outdoor gobo projectors available. Their versatility and durability make them an unbeatable tool for outdoor promotions. BulbAmerica has all of Griven gobo projectors plus more! Check it out.
