Nanotech Could Make Incandescent Light Bulbs As Efficient As LEDs (sciencemag.org)

Posted by samzenpus on from the making-it-better dept.

sciencehabit writes: Thomas Edison would be pleased. Researchers have come up with a way to dramatically improve the efficiency of his signature invention, the incandescent light bulb. The approach uses nanoengineered mirrors to recycle much of the heat produced by the filament and convert it into additional visible light. The new-age incandescents are still far from a commercial product, but their efficiency is already nearly as good as commercial LED bulbs, while still maintaining a warm old-fashioned glow.

    LED bulbs are superior to everything else, prove me wrong. (you can't)

    I put an LED bulb in my Lava Lamp. Now the goo just sits there on the bottom.

    Phillips. I still have a Phillips CFL from 15 years ago (with three arch tubes) that hasn't died yet.

    They would probably like to buy it from you so they can figure out what went wrong with it not dying, so they can prevent it happening again...
