Efficient incandescent bulb cannibalizes its own waste heat
A team of researchers from MIT announced Monday that they have developed a novel method to make conventional incandescent lights far more energy efficient. Incandescents, the ones with the white hot filament in the middle, are notorious energy hogs because they generate massive amounts of waste heat in addition to light.
Philips wins DOE's $10 million L Prize for 60W incandescent killer
Put your pig-tail light bulb aversions aside, because Philips has just won the DOE's $10 million L Prize Competition for the creation of a decidedly non-curlicue 60W equivalent LED lighting solution. The company was named the first winner in the 60W replacement bulb category at a Washington DC event, yesterday. It's taken three years to find a winner that could meet the high standards set forth by the DOE, specifically "ensuring that performance, quality, lifetime, cost, and availability meet expectations for widespread adoption and mass manufacturing." Requirements further stipulated that the 60W incandescent killer use less than 10 watts of power, and provide energy savings of 83 percent. If Americans replaced all of their 60W incandescents with Philips' little winner, the DOE estimates savings of $3.9 billion in a single year. The bulb is expected to hit shelves as soon as early 2012. Full PR after the break.
Velve OLED lighting panels cover a broader spectrum (video)
The University of Michigan may boast the best blue, but Mitsubishi subsidiary Verbatim is showing off OLED lighting of a different color; several of them, actually. Demonstrated this week at the Fuori Salone show in Milan, these 14 x 14 cm Velve-branded lighting panels are amongst the first color tunable OLED light panels, giving off what Verbatim calls "colourful lighting with a luxurious feel; as smooth and as rich as velvet." Velve. Velvet. See what they did there? Sample Kits will be available in Japan later this month for ¥90,000 ($1,063), and Verbatim hopes to see the technology put to use in consumer products by the end of the year. Suddenly white light OLEDs look positively old hat -- here's hoping the price comes down before we burn through our incandescent stockpile.
Cree shows off 'no-compromise' LED replacement for 60-watt incandescent bulbs
Compact fluorescent (or CFL) bulbs may currently be the dominant alternative to traditional incandescent light bulbs, but there's still a strong contingent betting on LEDs as the true long term replacement. One of the major players in that camp is Cree, which recently teamed up with TESS and Dean Kamen's FIRST organization to have kids distribute LED light bulbs like Girl Scout cookies (seriously), and is now showing off what is says is the "first no-compromise replacement for a 60-watt incandescent bulb." That bulb is dimmable, and emits a "beautiful, warm, incandescent-like color of 2700 K," while delivering more than 800 lumens and consuming less than 10 watts (meeting the Energy Star requirements for a 60-watt standard LED replacement bulb). Unfortunately, there's one big catch -- the bulb is still just a prototype, and Cree says it hasn't yet decided how it will bring it to market, or how much it might cost. Head on past the break for a quick video demonstration.
IKEA becomes the first major retailer to stop selling incandescent light bulbs
Remember The Energy Independence and Security Act of 2007 which mandated that all US retailers must stop selling incandescent bulbs by 2012? If you don't, you're apparently not alone, since according to a lighting survey conducted for IKEA back in 2010, 61% of Americans weren't aware of the legislation either. Luckily for those not in the know, IKEA was kind enough to remind the world of the upcoming change by proudly announcing that they've stopped selling the power-sucking bulbs a whole year early -- making them the first retailer in the US to comply with the bill. To help customers deal with the switch the furniture giant will sell visitors compact fluorescent and halogen bulbs -- in addition to LED lamps. That's seems like smart business considering the same lighting survey says 67% of Americans care about using energy saving lights, while 81% say using more efficient lights is a good environmental practice. So much for incandescent bulbs making a comeback eh?
GE closes last US factory making incandescent light bulbs
There may still be plenty of competition among potential successors to the incandescent light bulb, but there's little question that the traditional light bulb is on the way out -- a fact now further backed up by GE's closing of the last major factory making the bulbs in the US. GE had apparently considered a $40 million investment to retrofit the plant -- located in Winchester, Virginia, and employing some 200 workers -- to manufacture compact fluorescent light bulbs, but it says that bulbs made at the plant would have cost 50 percent more than ones from China, which is where the vast majority of CFLs are made. Of course, that shift hardly happened overnight -- be sure to hit up the Washington Post article linked below for a brief history of what led to this point, and a closer look at the plant itself.
Tea kettle concept almost boils your water with an incandescent light bulb
Incandescent light bulbs are definitely not in fashion these days (the last time we stepped inside Ikea we were greeted with their announcement that the company plans to stop selling them) because of their total lack of efficiency. Don't tell that to this concept for a tea kettle, however, which uses the wasted energy of the bulb (nearly 98 percent) to make water for your tea. Now, it doesn't actually bring it to a boil -- just to 194 degrees Fahrenheit -- but many tea enthusiasts will tell you that your water should be just off the boil anyhow. So there.
Nokero debuts rugged, rainproof N100 solar light bulb for developing worlds
Oh, sure -- the world has plenty of those ritzy LED light bulbs to choose from, but how's about using the ultimate light source to create... even more light! That's exactly what Nokero is setting out to accomplish with its N100, which is being christened the "world's first" solar light bulb. Designed specifically for use in developing nations where continual electricity is a mere pipe dream, this bulb is housed in an ultra-rugged, rainproof enclosure that can provide around four hours of light when fully charged; if you leave it in the sun all day, it'll harness enough juice to provide illumination for around two hours. The unit itself is constructed from impact resistant plastic and includes a foursome of solar panels, five LEDs and a replaceable, nickel metal hydride battery that's said to last two years. The company informed us that these will run you around $15 if purchased one at a time, though the goal is to sell 'em in bulk for around $6 apiece and have them delivered to rural parts of India, Africa and possibly District 9. Go on and get schooled by heading past the break and clicking play. %Gallery-94767%
LED traffic lights don't melt snow, do cause accidents
A number of cold weather American states are reporting their dismay at finding out that LED traffic lights are so energy efficient that they do not produce enough excess heat to dissipate any snow that covers them. It turns out, perhaps in an homage to bad engineering everywhere, that the inefficiency of incandescent light bulbs was previously relied upon to keep traffic signals unimpeded. The new LEDs do not achieve the same effect, which has resulted in a few accidents and even a death being blamed on obstructed traffic lights. Feel free to apply palm to face now. It's not all gloomy, though, as the majority of people are said to treat a dysfunctional traffic light as a stop sign (how clever of them), and a tech fix is being worked on as we speak.
OSRAM Orbeos OLED lights are small, flat, right behind you
The days of OLED wallpaper are still some years away, but you can finally start thinking about replacing those tired light fixtures with something a little more two-dimensional. After testing the waters with its Early Future lamp and then boosting efficiency of its product, OSRAM is announcing availability of Orbeos OLED panels for general consumption. The discs are 80mm wide, only 2.1mm thick, and emit light at a temperature of 2,800K, meaning they're much closer to an average incandescent than those awful CFLs. They're not as efficient, though, managing just 25 lumens per watt compared to your average CFL's 60 - 72. Still, they're about twice as thrifty as traditional bulb tech and can be configured in a variety of interesting ways (shown after the break), but since the company isn't saying just how much any of those configurations will cost we have to figure it's still going to be awhile before you're mounting these under your cabinets.
Study says LEDs are about as efficient as compact fluorescents, all things considered
As we've seen with the slight resurgence of new and improved incandescent light bulbs, the amount of energy used to actually light up the bulb isn't necessarily the whole measure of energy efficiency. There's also the small matter of producing the bulb, shipping it around the world, and eventually disposing of it. With that in mind, the Siemens Corporate Technology Centre for Eco Innovations conducted a study that compared regular compact fluorescents to LED lamps -- using one 25,000-hour LED lamp as a constant, compared to 2.5 10,000-hour compact fluorescents (and 25 1,000-hour incandescents). While it's still holding back on some of the finer details, the group did apparently find that LEDs are no more or no less energy efficient than compact fluorescents when the entire lifecycle of the bulb is taken into account, although it is quick to point out that LEDs should eventually win out as they become more efficient to produce.
Incandescent bulbs making a comeback, GE still launching new LED lights
On the eve of Christmas 2007, quite a few obituaries for incandescent light bulbs were penned. News was slow, time was short and Congress had just outlined a new energy plan that would essentially force these energy-wasting bulbs out by 2012. Now, however, legions of scientists are racing the clock to develop new incandescents that will still meet the upcoming guidelines, with a Deposition Sciences technology paving the way for a post-2012 model from Philips. Without drowning you in technobabble, let's just say that said tech has seen 50 percent efficiency gains in the lab, which is more than enough to please even the most outspoken tree hugger in Washington. In related news, GE has issued two more LED light bulbs: the 7-watt Energy Smart LED PAR20 and 10-watt LED PAR30. Both of 'em are aimed more at commercial customers than at actual homes, but you'll be hard pressed to find a better option for lighting up your makeshift basketball court.Read - Incandescent bulbs stage comebackRead - GE Energy Smart bulbs
Incandescent light bulbs be to shelved by 2012 in US
Better late than never, right? Regardless of your feelings on said mantra, the United States of America has finally passed a law barring stores from selling incandescent light bulbs after 2012. 'Course, the EU and Australia have already decided to ditch the inefficient devices in the not-too-distant future, but a new energy bill signed into law this week throws the US into the aforementioned group. Better grab a pack of the current bulbs while you still can -- soon you'll be holding a sliver of history.[Image courtesy of HD]
GE develops high efficiency incandescent bulbs
Incandescent is getting a pretty bad name in today's going-green society, but GE wants to salvage the tech with innovation before it's scrapped for the ages in laws that ban its use at home and abroad. GE's new high efficiency incandescent (HEI) lamp doubles the efficiency of today's 15 lumens-per-Watt incandescent bulbs achieving something closer to fluorescents -- which GE claims has the potential of saving supposedly hundreds of millions of tons of carbon dioxide annually, if adopted universally, of course. We doubt it's any coincidence that this announcement was made so shortly after the Australia's law and California's bill against incandescent bulbs, but the message is clear: save power, or Croc Dundee and the Governator will hunt you down and bad things will happen.[Via Slashdot]
