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.
