CREE® announces major LED advances at Strategies in Light

Filed under:

BURLINGAME, CA — Feb. 8, 2005 — Cree, Inc. (Nasdaq: CREE), a market leader in LED solid-state lighting components, today announced at the Strategies in Light industry conference development results that are likely to speed the adoption of LED technology into major lighting applications. The results were:

  • 100 lumens per watt and 50 percent wall-plug efficiency from standard 5 mm LEDs.
  • Maximum luminous flux of 60 lumens from its 7090 series white XLamp™ power LEDs operating at 350 mA.

“We are demonstrating significant levels of brightness and efficiencies from both standard and power LEDs. White LEDs are on a critical path toward significantly reducing energy costs for lighting throughout the world. Although there is significant development work to be done, I believe the LED industry is advancing toward replacing the light bulb at a more rapid pace than just a few years ago,” stated Chris James, Cree Lighting® marketing manager.

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 commercial products with performance ratings comparable to the development results discussed in the release; the potential lack of customer acceptance even if such products are developed; the possibility we may be unable to manufacture such 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 for such products; 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 27, 2004 and subsequent filings.
