Lighting the World

Nature

Scientists have created commerically-viable organic LEDs which can illuminate a room. These OLEDs are far more efficient than incandescent bulbs and cheaper to produce than fluorescent lights. Current LEDs have the problem that, other than their limited light producing capabilities, the blue dye in them degrades relatively quickly, causing the light to turn yellow. The new dye being use lasts around 10,000 hours. Compare that to the lifespans of incandescent bulbs, 1,000 hours, and fluorescent lights, 20,000 hours. Actually, I'm rather surprised by the huge disparity in lifespan between incandescents and fluorescents. I never thought it was that much.
