Cree Inc., the LED maker of Durham, North Carolina USA, announced the commercial availability of the XLamp XP-G LED. Cree says that the XP-G LED can produce up to 367 lumens when driven at 1A. This translates to a typical efficacy of 111 lumens per watt. The company points out that it is 46 percent brighter and 64 percent more efficient than the highest-performance XR-E LED, with an 80 percent smaller footprint. Furthermore, the company says that it offers even higher efficacy of 132 lm/W at a lower current of 350mA. Cree indicated that this high efficacy level at both high and lower current can reduce the number of required LEDs, thereby reducing the cost and size of the LED fixture.
“This establishes a new level of performance for LEDs,” said Paul Thieken, Cree director of marketing, LED components. “We now deliver lighting-class efficacy at 1A drive current. In addition, we have begun offering limited samples of an S2 flux bin, providing up to 400 lumens at 1A. We target availability of XP-G neutral and warm white LED samples by end of calendar 2009.”
The cool white XP-G LED is available with up to 139 lumens minimum at 350 mA, and it comes in ANSI-compliant cool white bins (5000K – 8300K CCT).
