New light bulb regulations light up the New Year

New regulations are phasing out less energy efficient incandescent light bulbs with new more energy efficient light bulbs.

Starting January 1st, the incandescent light bulbs will phased out for new greener technology.

The first to be blacked out is the 100-watt bulbs, in 2013 the 75-watt bulbs, and in 2014 the 60-watt bulbs. The changes to light bulb regulations were part of the Energy Independence and Security Act of 2007 and was signed into law on December 19, 2007 by George W. Bush.

The law requires new environmental standards when it comes to light bulbs. According to the Washington Post, the law does not remove incandescent light bulbs off of store shelves - they just need to comply to new energy efficient standards. In addition to the newer higher-efficiency incandescent bulbs, compact fluorescent or light emitting diode (LED) bulbs will be the new greener replacements.

Ring Out The Old and Ring In The New: LEDs Light Up Times Square

Beginning in 2012, the Energy Independence and Security Act goes into effect. EISA establishes efficiency standards that state that bulbs need to use 25% less energy than traditional light bulbs. Many choices are currently available, with the newest being the LED. Philips Lighting is marking their 12th year serving as the official lighting partner to the Times Square New Year’s Eve Ball.

The ball will be lit with 32,256 Philips LUXEON LEDs that consume 80% less energy than traditional incandescent bulbs. That same technology is used in the Philips AmbientLED line of consumer light bulbs. The 12.5 W AmbientLED is the world’s first commercially available LED to replace the 60 W incandescent bulb and be Energy Star qualified.

“We are proud that our award-winning Philips LEDs will again light the spectacular Times Square Ball,” said Ed Crawford, CEO of Lamps, Lighting Systems and Controls for Philips Lighting. “But we are equally proud that our line of Philips AmbientLED bulbs continues to expand, enabling consumers to use energy-efficient, cost-friendly, long-lasting and aesthetically-pleasing lighting throughout their homes.”

To get a better view of the Times Square Ball, Philips is hosting an online video web chat with Ed Crawford from the viewing platform of 1 Times Square on December 30th from 1:30-2:15 EST. Topics that will be discussed include:

• How will EISA impact energy consumption in the individual home?
• What is the future and benefits of LED technology?
• What are the consumer benefits of switching to more energy efficient lighting solutions?
• What are the uses and benefits of LED technology on the Times Square Ball?
• What are the differences between traditional light bulbs, halogens, CFLs and LEDs?

2012: Year Of The LED Light Bulb?

If everyone in the U.S. transitioned to energy efficient lighting in their homes,according to Phillips, consumers would avoid 87.5 million metric tons of carbon dioxide emissions and generate energy savings of $15.8 billion – a fact the company would like you to remember as you’re watching the LED Light-laden ball drop in Times Square.

New Year’s 2012 will mark the 12th consecutive year that Philips Lighting has served as the official lighting partner to the Times Square New Year’s Eve Ball. And while efficient light bulls have become a political issue in Washington, D.C., for Philips they’re a selling point. The company is highlighting the fact that the same technology used in the Times Square ball can also be found in the Philips AmbientLED line of LED Light Bulbs. These bulbs include the Philips 12.5-watt AmbientLED A19, the world’s first commercially available LED to replace the 60-watt incandescent bulb and the only to be Energy Star qualified.

Like the 32,256 Philips Luxeon LEDs that light the glittering Times Square ball, Phillips AmbientLEDs bulbs consume up to 80 percent less energy than traditional incandescent bulbs. (Though you may not want to keep yours lit up all year round, the way the LEDs on the ball at Times Square are.)

Though pricier ($40-$50 a pop) LED bulbs have been slow to take off in 2011, Phillips cites the fact that it has recently dropped the prices on this line of light bulbs and fact that instant rebates available from utility companies in many parts of the country as compelling reasons to make the switch in 2012.

Energy-Efficient Philips LEDs Light the Times Square New Year's Eve Ball

Innovative technology also used in ever-expanding line of Philips AmbientLED bulbs for consumer use
Free online video web chat with Ed Crawford, CEO of Philips Lamps, Lighting Systems and Controls on December 30th from 1:30PM - 2:15PM ET from the viewing platform of 1 Times Square - home of the Times Square Ball

NEW YORK, Dec. 20, 2011 /PRNewswire/ --

When the glittering Times Square New Year's Eve Ball descends to mark the beginning of 2012, it will also usher in one of the most important eras in lighting since Thomas Edison unveiled his incandescent electric light.


On January 1, 2012, new U.S. energy and lighting standards under the Energy Independence and Security Act (EISA) go into effect, and Philips Lighting – whose light-emitting diode bulbs (LEDs) light the Times Square Ball – is ready. Consumers may purchase a wide range of Philips LED bulbs for home use, online and at thousands of retail outlets.

New Year's 2012 marks the 12th consecutive year that Philips Lighting has served as the official Lighting Partner to the world-famous Times Square New Year's Eve Ball. The same technology used in the Ball is also used in the Philips AmbientLED line of consumer light bulbs, which includes such innovations as the Philips 12.5-watt AmbientLED A19, the world's first commercially available LED to replace the 60-watt incandescent bulb and the only to be Energy Star qualified.

"We are proud that our award-winning Philips LEDs will again light the spectacular Times Square Ball," said Ed Crawford, CEO of Lamps, Lighting Systems and Controls for Philips Lighting. "But we are equally proud that our line of Philips AmbientLED bulbs continues to expand, enabling consumers to use energy-efficient, cost-friendly, long-lasting and aesthetically-pleasing lighting throughout their homes."

Like the 32,256 Philips LUXEON LEDs that light the glittering Times Square Ball, the commercially-available Philips AmbientLEDs bulbs consume up to 80 percent less energy than traditional incandescent bulbs. That's why the Times Square Ball stays lit year round, and why consumers can reap significant electricity savings by making the switch to Philips LEDs. For example, if everyone in the U.S. transitioned to energy-efficient lighting in their homes, consumers would eliminate 87.5 million metric tons of carbon dioxide and generate energy savings of $15.8 billion.

With recent price reductions and the availability in many markets of instant utility company rebates, the price of Philips AmbientLEDs is lower than ever – further adding to its already significant economic impact.

Incandescent lightbulbs win congressional reprieve at 11th hour

Congress didn’t just agree to keep the government’s lights on through the rest of the fiscal year. It is also ensuring it has the option of doing so with high-energy-consuming incandescent 100-watt lightbulbs.

Under a law that President Bush signed in 2007, the Department of Energy on Jan. 1, 2012, was supposed to begin enforcing a ban on the incandescent bulbs that Thomas Edison perfected 132 years ago.

But the House and Senate’s massive spending bill to yet again avert a federal government shutdown includes a rider that will prevent the lightbulb rules from taking effect until at least October. Proponents of the lightbulb legislation promote it as an easy and logical way to improve the nation’s energy efficiency, but, to others, the law smacks of textbook government overreach.

Aficionados of the pear-shaped lights are stocking up on them at Home Depot — which reports lightbulb sales are up 10 to 20 percent over a year ago — and elsewhere before they fade away.

In Texas, the legislature passed a bill permitting the manufacture and sale of the traditional bulbs within its borders even though there is not a single lightbulb factory in the state.

Over the summer, a bill to repeal the energy-efficiency standards died in the House. Reps. Diana DeGette, Jared Polis and Ed Perlmutter, all Colorado Democrats, opposed it. Reps. Scott Tipton, Doug Lamborn, Cory Gardner and Mike Coffman, all Colorado Republicans, favored it.

Now there is a reprieve for the incandescent bulbs, but it may be too little, too late.

Even if Republicans are successful in further pushing back the efficiency standards that the incandescent bulbs don’t meet, with a focus on compact fluorescent, halogen and light-emitting diode versions. With many of the world’s other leading nations also phasing out the old energy-guzzling bulbs, companies are investing in newer technologies.

Democrats, along with lightbulb manufacturers such as General Electric Co. and environmentalists, are urging for new rules to take effect sooner than later, citing energy and cost savings.

“If America is to have a rational energy policy, we need to make progress in efficiency,” Sen. Jeff Bingaman, D-N.M., said in a prepared statement. “Blocking funds to enforce minimum standards works against our nation getting the full benefits of energy efficiency.”

Incandescent Light Bulbs to Stay Around Longer

A spending bill will block the federal government from phasing out 100-watt incandescent light bulbs in favor of more energy-efficient bulbs. The ban was to go into effect on Jan. 1.

The bill would fund the government by Sept. 30 of next year, but would not get rid of the incandescent bulb.

“There are just some issues that just grab the public’s attention. This is one of them,” Rep. Greg Walden, a Republican from Oregon, told Politco. “It’s going to be dealt with in this legislation once and for all.”

Republican Rep. Joe Barton of Texas said the GOP “strongly support” keeping language in the bill stating that incandescent bulbs stay for a little while longer, according to the political news website.

However, Democratic Sen. Bingaman from New Mexico decried the GOP-led move to keep the bulbs around longer, stating that “blocking funds to enforce minimum standards works against our nation getting the full benefits of energy efficiency,” according to Bloomberg News.

Choose the right light bulb:

Experts Say LED Holiday Lights Last Longer, Save Energy

LED lights can save you some money this holiday season, and they'll likely last for decades. NY1's Consumer Watch reporter Asa Aarons filed the following report.

LED or light-emitting diode lights illuminate more coolly than traditional bulbs. You can also string more together.

But what about the cost?

Many retailers report that this season, LED sales are close to those of regular incandescent lights, and the high LED price has come down to make them competitive.

At the New York State Energy Research and Development Authority (NYSERDA), they've been doing cost analysis between newer LEDs and traditional bulbs.

“They use about 70 percent less energy than a normal incandescent light and last 10 times longer. So they’re much more durable, they use less energy,” says Cameron Bard of the NYSERDA.

According the U.S. Department of Energy, 10 sets of 100 LED bulbs would only cost 60 cents a month to operate, compared to up to $26 dollars for traditional lights.

LEDs have an estimated life of 20,000 hours—about 40 holiday seasons.

LED lights are safe and contain nothing harmful. The same cannot be said for their compact fluorescent cousins. CFLs contain a substance that could potentially put a damper on Christmas or any other holiday.

“It does contain a small amount of mercury, so you want to be careful. That means if you’re gonna dispose of it, you wanna always take it to a hazardous recycling center. If it does break, you want to seal it up and take it to one of those centers right away,” says Bard.

Millions of the fluorescent bulbs are doing a nice job illuminating low-traffic areas like closets and basements. Holiday bulbs are often moved and jostled, so you should be the judge. Whichever light type you go with, NYSERDA recommends a timer to switch them on and off each day. They say it’s not overkill.

“What we’ve continually found is that when people need to rely on behaviors, they oftentimes forget. This eliminates human error,” says Bard.

Philips to continue incandescent bulb phase-out

Royal Philips Electronics has announced that it will continue its independent efforts to phase-out incandescent light bulbs in the GCC.

After Philips’ 100-watt and higher phase-out of energy inefficient light bulbs in September 2010, the company decided to discontinue and replace the 75-watt incandescent lamps as of January 2012, with energy-efficient alternatives like compact fluorescent lamps (CFLs), energy-saving halogens and LED bulbs.

Philips invented the energy saving light bulb in 1980, and continued to develop energy efficient lighting solutions as a proof-point of their efforts and commitment to sustainability and the environment, a statement from the company said.

Lighting accounts for 19 percent or one third of the world’s electricity consumption, where 90 percent of the energy used through an incandescent light bulb is wasted as heat, according to the International Energy Agency (IEA).

However, 80 percent savings can be made by simply converting from traditional conventional lamps to energy saving ones, it said.

In the GCC alone, switching all residential lighting to energy efficient solutions will reduce a tremendous amount of CO2 emissions yearly.

With this switch, consumers will not only preserve the environment but also be able to save on their electricity bills without compromising on the quality of light, instead, creating the perfect ambiance at home.

“Homes are currently dominated by incandescent bulbs, and approximately two third of the world’s lighting solutions in use are based on old, less energy efficient technologies”, says Paolo Cervini, general manager of Philips Lighting, Middle East & Turkey. “Making a switch to energy efficient lighting solutions is simple and easy, with a remarkable effect.”

“Philips is aware that significant savings can be made in terms of energy consumption, carbon emission and costs by switching to energy efficient solutions, therefore, we continue our unilateral phase-out of incandescent lamps and simultaneously educate the public through different initiatives on the benefits of the switch,” he added.

Compact fluorescent energy savers are up to five times more efficient than incandescent lamps, as they need around five times less energy to generate the same amount of light, the statement said.

Philips CFLs lasts an average of eight times longer than incandescent lamps, needing less frequent replacements. The Philips Genie 14W which can be used as an alternative to the incandescent 75-watt light bulb is an ultra-efficient lamp which saves up to 80 percent energy and has a lifetime of 8,000 hours. – TradeArabia News Service

Vending Machine a Bright Idea for Light Bulb Recycling

UK based Revend Recycling has launched a reverse vending recycling machine to collect and recycle domestic light bulbs and batteries.

The company claimed that the reVend reverse vending recycling machine is the first domestic such machine in the world targeting domestic light bulbs, and has been jointly designed and developed with Norwegian recycling vending machine specialist, Repant.

Accordint to Revend, the machine has features and optional add-on unit for the collection and recycling of domestic batteries, which contain valuable and scarce natural mineral resources.

Repant will manufacture /assemble the recycling machines based on its COSMOS reverse vending recycling machine technology, while Revend will sell & market unique reverse vending recycling machines throughout Europe, USA & worldwide.

According to Revend the product includes the in-built technology safely recycles light bulbs containing mercury and other hazardous materials, while user automatically receives a reward incentive voucher which can be used for product discounts and sales incentives.

In addition, staff at the machine's locations will not need to touch the potentially harmful recycled light bulbs when removing from the recycling bin.

The company said that the machine is also able to compile of auditable statistics on bulb types by manufacturer and volumes recycled.

According to Revend, recycling rates in the domestic lighting industry are in sharp focus internationally, as significant waste tonnage amounts remain untreated and unprocessed and used light bulbs frequently end up in landfill sites at considerable environmental and financial cost.

Revend said that it has recently concluded a supply agreement with IKEA of Sweden, a leading international retailer, and will install a significant number of machines in several IKEA stores throughout Europe, including the UK, Germany, & Denmark.

New Rules for Light Bulbs Mean Lower Electric Bills

Chalk it up to progress, pollution control and energy security. In January, as more provisions of the Energy Independence and Security Act of 2007 kick in, Thomas Edison's brilliant invention, the incandescent light bulb, will have to shape up or ship out. The old-style bulb is targeted for obsolescence because it converts just 10% of the electricity it uses into light and radiates the rest as heat.

SEE ALSO: Tools and Tricks to Slay Your Home's Energy Vampires

Under the law, incandescents are not banned, nor are compact fluorescent (CFL) bulbs mandated as replacements. Manufacturers and wholesalers do have to meet new standards that are forcing them to improve the efficiency of incandescent bulb or replace them with newer technologies.

The law phases in over the next two years, and the 100-watt bulb is the first victim. (California implemented the law a year ago.) The Department of Energy says that the average household that replaces 15 traditional incandescent bulbs will save $50 annually on its energy bill -- and the newer bulbs last longer.

You have three main alternatives:

Halogen incandescents ($4 to $8 per bulb) offer energy savings of 25% and an expected life of up to three times longer than traditional incandescents -- plus a brightness level and light color comparable to that of traditional bulbs. Annual savings if you replace 15 60-watt incandescent bulbs: $19.50.

CFLs ($1.75 to $2, even after a spike in CFL prices after China restricted the supply of rare earth metals used in the bulbs) offer energy savings of 75% and last ten times longer than old-fashioned bulbs. Annual savings: $54.

Light-emitting diodes , or LEDs ($10 to $26), provide an average energy savings of 75% to 80% and last up to 25 times longer. Annual savings: $57. LEDs are pricey, but costs will drop as more products come to market.

Light bulb ban creates public health risks

On Jan. 1, less than one month from now, the government-mandated ban on the sale of tried-and-true 100 watt incandescent light bulb will go into effect. As a result, consumers will have no choice but to buy alternative light bulbs such as compact fluorescent lamps (CFLs). Therefore, it is time to take stock of the significant health hazard posed by the presence of mercury in those bulbs.

Recognizing the harmful effects arising from exposure to the mercury in CFLs, the Environmental Protection Agency has published a set of guidelines on handling broken CFLs. These guidelines call for residents of a house to immediately open a window in the contaminated room (if there is one), shut off any central, forced-air heating and air-conditioning systems serving the contaminated room, and then leave the room and preferably the building without walking through the breakage area.

Those left behind to clean up the contaminated area are advised to scoop up the broken pieces of the lamp and to place them in a sealed plastic bag, to wipe the contaminated area clean with damp paper towels or the like, to place the used paper towels in a glass jar or plastic bag and to then seal the jar or plastic bag. Clothing or bedding that may have been contaminated by the broken lamp should not be washed, but instead thrown away, presumably in a sealed plastic bag.

These guidelines may be austere, but for good reason. Exposure to the mercury vapors in a broken CFL can cause cancer and damage to vital internal organs such as the liver and lungs. Inhalation of the mercury vapors also can lead to blindness in young children.

In publishing these guidelines for handling broken CFLs, the EPA has chosen not to tell the public about the health hazards arising from exposure to the mercury vapors. The guidelines also neglect to advise those responsible for cleaning up broken bulbs about taking measures to minimize the harmful effects inevitably arising from exposure to the mercury fumes. Perhaps the harmful effects cannot be avoided, short of donning a protective Hazmat suit. The federal government also has chosen not to require CFL manufacturers to place a warning on packages about the health hazards associated with the mercury. (A skull-and-crossbones might be in order in view of the severe health risks mentioned above.)

Instead, CFL packages on store shelves merely state that the lamps contain mercury, leaving it to the consumer to ferret out the associated health risks.

When all is said and done, it seems that our federal government and those environmental zealots favoring the use of CFLs have gone out of their way to avoid informing the public about the severe health hazards associated with them. They seem to think that greater good will come from the reduced energy arising from the use of CFLs and the corresponding reduction of emissions from burning fossil fuels needed to supply the needed electricity.

Energy-efficient alternatives to the 100-watt light bulb

At the beginning of this year, California became the first state to begin phasing out regular incandescent 100-watt light bulbs. The rest of the nation will follow suit this January, and the old 100-watt bulbs will no longer be imported or produced.

Even though the newer replacement bulbs cost more, over time, they could save you a bundle. The incandescent 100-watt light bulbs are cheap, but they're energy wasters.

Consumer Reports tested replacement options - CFLs and halogens, as well as a combination halogen-CFL bulb from GE. That bulb had trouble in the rapid-cycle test, where the light is turned on and off every two minutes.

"With the six we tested, the CFL part burned out after only about around 3,000 cycles - that's much faster than any other bulb," said Consumer Reports' Celia Kuperszmid Lehrman.

Consumer Reports also evaluated seven regular CFLs. They promise to last 10,000 to 12,000 hours. And they say they produce 1,600 lumens, the equivalent of a 100-watt incandescent.

Testers used special equipment to measure a bulb's brightness after it'd been burning 3,000 hours.

"With all the CFLs we tested, the brightness dropped down to between 1,280 lumens and about 1,400 lumens," said Lehrman.

But when reading, panelists didn't necessarily prefer the brighter light.

Among 100-watt equivalent CFLs, Consumer Reports says your best choices are the ECObulb Plus from Feit Electric for around $2.

And for even less, try the Utilitech Soft White from Lowe's and the EcoSmart Soft White from Home Depot.

"Halogen bulbs don't last anywhere near as long and they won't save you very much money, but they did keep their full brightness in our tests," said Lehrman.

Consumer Reports recommends the 100-watt equivalent Philips Halogena Energy Saver for $5.50.

A plus: halogens can be dimmed, unlike many CFLs, and they reach full brightness immediately.

Consumer Reports calculates that CFLs can save you $100 or more over the lifetime of the bulb. Halogens will only save you about $3.

Flat Light Bulbs

Light bulbs
are…well bulbous. They take up way too much room, are a pain to store due to their shape, etc. Those newer corkscrew deals are no better. It’s an old design for an old world. That’s why Joonhuyn Kim’s concept makes sense. (Pics)Flat bulbs take up less space and make them easier to stack, store and transport. My only concern is that the odd shape would somehow make the light all weird on the wall. Great idea even if it is a bit late to the lighting arena.

LEDs and the Future of Light

Ask and Expert

Will LEDs eventually replace CFLs and incandescent bulbs?

Though the upfront costs are currently high, the future of LED light bulbs is bright. Gary Allen of GE Lighting notes the trend of falling costs per lumen—and what that means for the accessibility of the LED bulb.


What initially interested you about LEDs?

I’ve been doing R&D, Innovation, and New Product Introduction (NPI) in Lighting for 26 years—24 of those with GE. My sole focus has been helping to provide lighting solutions that push the envelope toward the ideal light source. Efficacy, color quality, life of the light source, cost, controllability, and infinitesimally small; LEDs are approaching most of those criteria probably 10x faster than any previous light source technology had progressed.

So for me, the opportunity to design new lighting products by leveraging these breakthrough capabilities of LEDs, in combination with the energetic and creative talent that we have within our Innovation and New Product teams at GE Lighting, is a career-long dream come true.


What makes LED lights particularly great as grow lights for plants?

Probably the two most desirable attributes in today’s plant-growing applications are the control of the spectral content of the light and high efficiency (low heat load and low operating cost).

Presently, most plant growing is done with blue and red light, but a recently emerging field in horticulture is the discovery that the ideal spectral content, and the ideal timing of both brightness and colors through the day and the seasons, is different for various types of plants. So, whereas most plant growing now uses blue and deep red LEDs, the future ideal horticultural light sources might have any number of tunable wavelengths adjustable to the specific plants being grown. No legacy light source can provide the combination of high efficiency, tunable spectral content, and controllability of LEDs.


With all the advantages of LEDs, will there continue to be a market for compact fluorescent light bulbs?

LEDs have many advantages over CFLs, but today’s higher cost of LEDs mean that for many consumers CFL is presently the best choice. CFLs are a phenomenally good investment for consumers right now based on electricity savings. The true cost of the 100W incandescent light bulb isn’t the $0.50 price of the bulb. The true cost also includes the electricity used over the 1000-hour life of the bulb, which averages about $12 for US consumers. So, each 100W incandescent bulb costs $12.50, not $0.50.

A typical CFL bulb lasts as long as eight incandescent bulbs. If the consumer buys eight incandescent bulbs instead of one CFL, the real cost of those eight incandescents is $100! CFL buyers understand that. They’re saving about $70 of that $100 for every 26W CFL that they buy. Putting one or two CFLs into your shopping cart might pay for everything else in the cart!

LED lamps that provide as much light as a 100W incandescent bulb are becoming available over the next year or so. They will use about 20-25 watts and will last 25x longer than the incandescent, but they might cost $50 or more. So, the payback time will be about five years versus the three to six months for the CFL.

Interestingly, gas-hybrid cars have about a five-year payback, too. Nonetheless, our intense focus among LED lamp manufacturers is to bring those prices down as quickly as possible. In five years, the cost of LED light bulbs should not be a concern for most consumers. They’ll get a nearly perfect light bulb at an affordable price, and each one will save them $100 or more.


Haitz’s Law says that every decade LEDs will become cheaper by a factor of ten. Do you think this will continue to be true?

Those incredible rates of progress for LEDs have been constant—hardly wavering—since the first visible LED was invented at GE’s Global Research Center by Nick Holonyak in 1962.

That means that over five decades, the cost per lumen has come down by 105. That means that a $1 LED today would have cost $100,000 50 years ago. Those of us who remember those days can attest that LEDs then were used only in expensive, esoteric applications, e.g. in space and in science. That cost trend suggests that today’s $1 LED will cost 10 cents in 10 years. That is a generally accepted projection in the industry, and we’ll probably get there. That forthcoming reduction in cost will make LEDs affordable in almost all applications, and they will probably be the dominant light source in most applications by 2020.


How long do you think it will be before LEDs replace incandescent light bulbs entirely?

The automobile still has not entirely replaced the horse and buggy, people still burn candles for light, and I hope that incandescent lamps are never entirely replaced. Apart from poor efficiency, they are a beautifully elegant product, and some consumers will always love them for special occasions. But, the industry projections suggest that in five years, INC lamp sales will be only about one percent of all lamp sales for general lighting applications. Edison’s iconic invention will have had a 135-year-plus run. I think he would have been extremely pleased.
