Bright idea: LEDs poised to replace light bulbs

PORTLAND, Ore. — A recent advance in light-emitting diodes may 
illuminate the path to replacing light bulbs with LEDs within the next 
five years, according to researchers.

Fred Schubert, a professor at Rensselaer Polytechnic Institute (Troy, 
N.Y.), claims to have invented a 99-percent efficient reflector that 
promises to speed the replacement of light bulbs with LEDs.

"Until now, all lighting systems, especially incandescent bulbs, 
generated more heat than light. But our 99-percent efficient reflectors 
for LEDs makes them the first candidate for light-bulb replacement that 
generates more light than heat," said Schubert.
