DURHAM, N.C., Sept. 7, 2007 (PRIME NEWSWIRE) -- 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(r) 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."

This press release contains forward-looking statements involving risks and uncertainties, both known and unknown, that may cause actual results to differ materially from those indicated. Actual results may differ materially due to a number of factors, such as the risk we may be unable to develop and release commercial products with performance ratings comparable to the development results described above; the risk we may be unable to manufacture products with sufficiently low cost to offer them at competitive prices or with acceptable margins; the rapid development of new technology and competing products that may impair demand or render our products obsolete; the potential lack of customer acceptance for the products even if they are developed; and other factors discussed in Cree's filings with the Securities and Exchange Commission, including its report on Form 10-K for the year ended June 24, 2007, and subsequent filings.
