  • New development could lead to more effective lightbulbs

    US researchers say they have developed a technique that can significantly improve the efficiency of the traditional incandescent lightbulb. These older bulbs have been phased out in many countries because they waste huge amounts of energy as heat. But scientists at MIT have found a way of recycling the waste energy and focussing it back on the filament where it is re-emitted as visible light. The development has been reported in the journal Nature Nanotechnology. Little has changed in the technology of the incandescent lightbulb since they were commercially developed by Thomas Edison in the US in the 1880s. Incandescent...

    The way we perceive color is greatly influenced by our cultural understanding. We all grew up learning that Fire is Hot and Ice is Cold. Therefor red and orange are warm colors while blue and cyan are cool colors.This association in our mind is so strong that filmmakers can actually invoke a sense of temperature just by the color palette they use in their films.Take for example Spike Lee’s 1989 film “Do the Right Thing”The film beautifully photographed by Ernest Dickerson, is awash in yellows, oranges and reds invoking the heat of a long, hot day in the Bed Stuy...

    The Obama administrations War on Carbon rages, but the good news is the incandescent light bulb still lives. For the third year in a row, the federal ban on the popular incandescent light bulb the choice of most Americans was postponed by Republican House intervention that defunded EPA enforcement of the law. None of the funds made available in this Act may be used . . . to implement or enforce the standards with respect to incandescent reflector lamps, reads section 322 of the $1.1 trillion budget signed by the president in January.

    Say goodbye to the regular light bulb this New Year. For more than a century, the traditional incandescent bulb was the symbol of American innovation. Starting Jan. 1, the famous bulb is illegal to manufacture in the U.S., and it has become a fitting symbol for the collusion of big business and big government. The 2007 Energy Bill, a stew of regulations and subsidies, set mandatory efficiency standards for most light bulbs. Any bulbs that couldn't produce a given brightness at the specified energy input would be illegal. That meant the 25-cent bulbs most Americans used in nearly every socket...

    No rules yet for recycling mercury-containing alternatives A federal ban on inefficient light bulbs goes into effect Jan. 1, 2014, almost seven years after it was announced with fanfare by a then-rookie Conservative government. But the tough regulations are being watered down, and there are no federal rules yet on recycling a class of bulbs that meet the new standard but contain toxic mercury.
  • Edison Bulb Ban Means Lights Out On Freedom: Importing 40 & 60 Watt incandescents illegal in 2014

    Bulb Ban: As of Wednesday, the manufacture and import of 60- and 40-watt incandescent light bulbs will be illegal one more setback in the fight against government interference into the daily lives of the American people. First they came for our light bulbs. Before the onset of ObamaCare and its mandate to buy health insurance as a condition of citizenship, there was the Energy Independence and Security Act of 2007 (EISA), one of the first things Democrats took up on retaking the House of Representatives in the 2006 elections. A well-intentioned President George W. Bush signed the incandescent bulb...

    Its lights out for the light bulb. On Jan. 1 it will become illegal to manufacture or import traditional 60-watt and 40-watt incandescent bulbs, thanks to a 2007 bill that set strict minimum efficiency standards and effectively outlawed the ordinary bulb. And like a politician on Election Day, Home Depot is urging consumers to buy early and often. Get them while you still can, the nations largest bulb retailer urges on its website. Stock up on incandescent light bulbs before they are completely discontinued.

    Light bulbs are changing. Federal rules taking effect Jan. 1 ban the manufacture of incandescent bulbs using 40 watts of power or more, the third phase of energy efficiency legislation passed in 2007. The intent of the law is to push consumers toward more energy-efficient lighting technology than the incandescent light bulb which has helped beat back the night for more than a century, but expends most of its energy producing heat rather than light. Compact fluorescent lamps those spiraling tubes that some consumers may associate with harsh light and delayed start-up cost more than incandescents but...

    PNNL ^ | 18, 2013 | Staff
    A PNNL staff member removed a burned-out compact piggy tail light bulb in his home and replaced it with a new one. When he turned on the switch, only a portion of the new bulb lit up. Assuming it was defective, he turned off the switch to remove it. Grasping the bulb, he felt a pain as if he had been cut by glass, and found a small, burn. Removing the bulb, he noticed the plastic base (see pix) was blackened at the point where it connected to the mercury tube.

    Starting next year, it's lights out for certain types of light bulbs in the United States. You'll no longer be able to buy an incandescent light bulb starting January 1, 2014. Under the Energy Efficiency and Security Act of 2007, signed into law by then- President George W. Bush, light bulbs must become more efficient in terms of energy used for generated light. That means incandescent lights are phased out. And you'll reduced to choose between a compact fluorescent (CFL) or light emitting diode (LED) bulb. For example, instead of burning 60 watts when you turn on the lights, you...

    Regulation: We dont often find ourselves agreeing with what most lawmakers say, but this week was an exception when a congressman explained why he wanted to prevent a federal ban on traditional light bulbs. "If the new energy-efficient light bulbs save money, and if theyre better for the environment, we should trust our constituents to make the choice on their own to move toward these bulbs," Rep. Michael Burgess, R-Texas, said. "Let the market decide." Imagine that! Trust consumers. Let the market decide. A common-sense idea that expresses basic economic principles. But such simple wisdom...

    There are many reasons why people get insufficient sleep in our 24/7 society, from early starts at work or school, or long commutes, to caffeine-rich food and drink. But the precipitating factor is an often unappreciated, technological breakthrough: the electric light. Without it, few people would use caffeine to stay awake at night. And light affects our circadian rhythms more powerfully than any drug. Just as the ear has two functions (hearing and balance), so too does the eye. First, rods and cones enable sight; and second, intrinsically photosensitive retinal ganglion cells (ipRGCs) containing the photopigment... --snip-- The US Institute...
  • GE 90 watt miser incandescent bulbs in stores

    GE has new 90 watt Watt-Miser bulbs on sale now due to the 100 watt incandescent bulb ban. You can find them at Wal-Mart. They are rated at 1450 lumens. But if you don't mind paying more, GE also has 72-watt halogen bulbs (rated as "100-watt equivalent") which put out 1490 lumens, so with those you get slightly better brightness with less energy being used.

    Scientists at the Wake Forest University have created a new type of light bulb that promises to be just as efficient as LED equivalents, but without any of the drawbacks. The new field-induced polymer electroluminescent bulbs FIPEL for short produce light when an electric current is passed through the nano-engineered plastic layers. The team says that the new type of bulbs are malleable, allowing them to take any shape like compact fluorescent lamps. They also wont shatter like traditional bulbs, nor will they generate the same hum or flicker. The inventor of FIPEL, Dr David Carroll, believes that...

In a voice vote, the House approved an amendment to the Energy and Water spending bill for 2013 that would prevent the Department of Energy from spending money to enforce a 2007 law that sets bulb efficiency standards. The law bans the sale of 100 watt incandescent bulbs and will ban the sale of 75 watt traditional bulbs in July 2013.This year, like last year, the amendment was sponsored by Rep.

Rep. Michael Burgess (R-Texas) will offer an amendment to Energy Department spending legislation that would block funding for implementation of the standards, the lawmaker's office told The Hill. The standards have come under fire from conservatives in recent years. Republicans won the inclusion of a similar provision in an omnibus spending compromise that House and Senate lawmakers agreed to in December. The provision blocked funding for implementation of the...
