New High-Efficiency Cree XLamp LED Can Reduce Initial Fixture Cost for Lighting Manufacturers
Dec 19, 2010 Cree has announced the commercial availability of XLamp XP-E High Efficiency White (HEW) LEDs. The new high-efficiency components extend the light output and efficacy of the XLamp XP-E LED family, enabling fixture designs that can use up to 50 percent fewer LEDs.
XP-E HEW LEDs are optimized to lower initial costs for diffuse lighting applications, such as LED replacement lamps and downlights. XLamp XP-E High Efficiency White LEDs are the first high-power LEDs featuring Cree’s new Direct Attach LED technology. Direct Attach technology is Cree’s unique, next-generation LED chip technology that delivers higher flux, lower forward voltage, and lower thermal resistance.
XLamp XP-E High Efficiency White LEDs deliver up to 148 lumens in cool white (6500K) and 114 lumens in warm white (3000K) at 350 mA. In addition to light output and efficacy improvements, XP-E HEW LEDs feature a reduced thermal resistance of 6 °C/W. XP-E HEW LEDs are available in the same white variations as XP-E LEDs, including Standard White, Outdoor White and 80-CRI White.
XLamp XP-E High Efficiency White LEDs are available now in sample and production quantities with standard lead times. IES LM-80 data for measuring lumen maintenance of LED light sources, for XP-E HEW LEDs, is targeted for availability in February 2011.
