CNET: Lighting The Future With LEDS
CNET reports on the increasing use of LEDS as replacements for incandescent bulbs in mainstream lighting applications. 'Right now, consumers and businesses can buy a light-emitting diode, or LED, that provides about the same level of illumination as an energy-hogging conventional 60-watt lightbulb, Steven DenBaars, a professor of material science at the University of California Santa Barbara, said at the SEMI NanoForum, taking place here this week. A principal advantage of the LED: It lasts about 100,000 hours, far longer than the conventional filament bulb.Unfortunately, the LEDs that can perform this task cost about $60, he said. (Prices vary on the Internet.) But prices have been declining by 50 percent a year, so two years from now the same LED should cost around $20'
