DURHAM, N.C. - Cree, Inc. (Nasdaq: CREE), a leader in LED lighting components, today announced that its award-winning XLamp XR-E LEDs are qualified for use in high-power applications of up to one amp (A). The XR-E LED produces luminous flux of up to 210 lumens at 1 A, with typical luminous flux of 176 lumens.

“The Cree XLamp XR-E LED is established as the industry’s best-performing power LED in production. To make the XR-E LED even better, it is now qualified for extended performance in higher-power applications, such a portable lighting, where maximum light output is required,” notes Norbert Hiller, Cree vice president and general manager for XLamp LEDs. “This qualification also applies to the millions of XR-E LEDs already in the field, so customers can be confident using their existing XR-E LEDs at the higher power levels.”
