Cree Achieves 1,000 Lumens from a Single LED

Cree, Inc. (Nasdaq: CREE), a leader in LED lighting components, today announced it has demonstrated light output of more than 1,000 lumens – an amount equivalent to the output level of a standard household light bulb – from a single R&D LED. Cree’s achievement demonstrates continued leadership in the development of LEDs that can make traditional light bulbs obsolete.

A single-die LED, driven at four amps, produced 1,050 lumens in cool white and 760 lumens in a warm-white version. Efficacy of the cool-white LED was 72 lumens per watt and 52 lumens per watt from the warm-white device. Both LED versions operated at substantially higher efficacy levels than those of today’s conventional light bulbs. Historically, Cree’s R&D demonstrations generally have been commercialized within 12 to 24 months.

“Cree’s XLamp® LEDs are the best-performing commercially available LEDs, but we won’t be satisfied until light bulbs are obsolete,” comments John Edmond, Cree co-founder and director of advanced optoelectronics. “We’ve worked 20 years to achieve lighting-class LED performance, and we still have plenty of ways to advance the technology further.”
