Progress on LED lighting
LED lighting has the potential of drastically reducing electricity consumption (most lighting on cell phones is already done via LED) while reducing several classes of electrical accidents. Lighting consumes over 25% of US electricity, most of it via incandescent bulbs. A typical 60w incandescent will produce about 700 lumens. A compact florescent of about 15w will also produce 700 lumens but they are expensive and fragile. It seems if it will be possible to get 700 lumens out of a 3w LED. The company announcement below discusses a product that would have some niche applications. Full disclosure - I own stock in this company.DURHAM, N.C., July 25 -- Cree, Inc., a market leader in LED solid-state lighting components, today announced that its new white 3-watt XLamp(TM) 7090 high power LED, with maximum luminous flux of more than 90 lumens, has been selected to power Cyberlux Corporation's powerful new RelyOn(TM) portable work and emergency light.
