Cree announces record 350 mA brightness and efficacy

Feb. 16, 2006
Date Announced: 16 Feb 2006 Cree, Inc. (NASDAQ: CREE), a leader in LED solid-state lighting components, today announced general availability of the industry’s highest efficacy white power LEDs at 350 mA.Cree’s white XLamp® 7090 power LED package achieves a typical efficacy of 47 lumens per watt at a drive current of 350 mA, and 57 lumens of typical light output. Cree also announced the availability of XLamp 7090 in warm white (2700-4500K) to address the emerging market for residential lighting applications."To replace the light bulb cost effectively with solid-state technology, LED manufacturers have to maximize the efficacy (lumens/watt) of their high-power LEDs. Energy savings is the most important metric as we build the business case for the residential lighting fixtures of today,” notes Manuel Lynch, Permlight Products president and CEO. “Cree has done a terrific job of providing us with highly efficient power LEDs allowing us to replace incandescent and compact fluorescent technologies in new homes throughout California. We are currently selling under-counter, step and pathway light fixtures based on the white XLamp 7090 power LED.”“This advancement is another step toward making LED lighting a reality in the general illumination market,“ notes Mark McClear, Cree director of marketing for lighting LEDs. “We have once again raised the bar for 350 mA operation, which is the benchmark for most solid-state lighting applications.”The XLamp 7090 power LED also features:* Reduced thermal resistance to 8°C/watt.* Electrically neutral thermal paths, allowing use of economical printed circuit boards.* Reflow solderability.For additional information on Cree LEDs, please call 919-313-5300 or visit Cree’s brightest XLamp 7090 LEDs will be featured in warm and cool white at Light + Building in Frankfurt, Germany, April 23-27, and at Lightfair International, May 30-June 1, in Las Vegas.About Cree, Inc.Cree is a market-leading innovator and manufacturer of semiconductors and devices that enhance the value of solid-state lighting, power and communications products by significantly increasing their energy performance and efficiency.
