Cree Delivers the First 160-Lumen White Power LED

XLamp LEDs now as efficient as fluorescent sources

Monday October 9, 2006

DURHAM, N.C., Oct. 9 /PRNewswire-FirstCall/ -- Cree, Inc. (Nasdaq: CREE - News), a leader in LED solid-state lighting components, today announced new benchmarks for power LED brightness and efficacy with the release of the newest white Cree XLamp® 7090 power LED. This new XLamp LED, available in volume quantities, produces luminous flux of up to 95 lumens or 85 lumens per watt at 350 mA, and up to 160 lumens at 700 mA.

Typical luminous flux for the new Cree XLamp 7090 LED is 80 lumens at 350 mA, yielding 70 lumens per watt. The new XLamp LED was designed to enable general lighting applications, such as street lighting, retail high bay lighting and parking garage low bay lighting, as well as to vastly improve the light quality in consumer applications such as flashlights. LED technology has been sufficiently bright for many general illumination applications for some time. The new XLamp 7090 LED, however, offers the efficiency and reliability needed to make LEDs cost-effective for more of these applications. The new XLamp 7090 LED is the first power LED based on the company's EZBright(TM)1000 LED chip, which provides the industry's highest efficacy at 350 mA.

"Cree LEDs are achieving efficacy levels formerly delivered only by the most efficient traditional lighting sources, including fluorescent bulbs. We have established a new class of LED performance," notes Mike Dunn, Cree general manager and vice president, lighting and backlighting LEDs. "Our goal at Cree remains to aggressively increase the brightness and efficacy of our LEDs to ensure that LEDs become a cost-effective, energy-saving alternative for all lighting applications."

"The Department of Energy is pleased to have been a contributing partner in the Cree research and development efforts that have achieved a new level of performance for power LEDs," notes Alexander Karsner, Department of Energy Assistant Secretary for Energy Efficiency and Renewable Energy. "Now, more than ever, our nation needs energy-saving technology that is top-quality and cost-effective. The Department will continue to work with Cree and other lighting-industry partners to turn advanced energy-saving technology into commercially available and successful products that save energy for consumers."

The Cree LED research and development efforts were enabled in part through funding from the Department of Energy's Building Technologies Program, within the Office of Energy Efficiency and Renewable Energy, and also in part through funding from the Department of Commerce's National Institute of Standards and Technology's Advanced Technology Program. Cree is also a charter member of the Department of Energy's Solid-State Lighting Partnership with the Next Generation Lighting Industry Alliance, an organization of lighting manufacturers that provides input to enhance the manufacturing and commercialization focus of the Department's solid-state lighting portfolio.
