Cree has Lighting-Class LEDs for Designing ENERGY STAR-Compliant LED Fixtures
Cree has the most lighting-class LEDs meeting the stringent U.S. Department of Energy (DOE) ENERGY STAR performance criteria, offering fixture manufacturers a significant benefit when designing with XLamp XR-E, XP-E or MC-E white LEDs.
The The DOE accepts Cree’s IES LM-80 test data for the Cree XLamp XR-E, XP-E and MC-E LEDs. This LM-80 test data can be submitted by luminaire manufacturers (along with the appropriate LM-79 optical and electrical data) to the DOE for ENERGY STAR approval of both 25,000-hour residential and 35,000-hour commercial lighting products.
“Cree has the broadest family of lighting-class LEDs accepted by the DOE for use in ENERGY STAR products,” said Paul Thieken, Cree director of marketing, LED components. “Our customers can avoid expensive and prolonged fixture testing by designing-in XLamp XR-E, XP-E or MC-E LEDs. Cree XLamp LEDs were also the first to be binned to ANSI C78.377A chromaticity back in 2007 and feature excellent white-point stability—further simplifying the design of LED fixtures to meet ENERGY STAR requirements.”
Further information on Cree’s LM-80 testing methodology can be found in the recently published Lumen Maintenance Application Note, available at www.cree.com/LM80. In addition, Cree’s lighting-class XLamp XP LEDs became UL-recognized on August 4, 2009 (registration file OOQA2.E326295). Due to the glass lens, Cree’s XLamp XR family and MC-E LEDs, are considered enclosures by UL and do not require registration.
