Cree claims 111lm/W XP-G is brightest and most efficient lighting-class LED

Cree Inc of Durham, NC, USA has announced the commercial availability of the Xlamp XP-G LED, which it claims is the brightest and most efficient lighting-class LED. The XP-G LED can produce up to 367 lumens when driven at a current of 1A, at a typical luminous efficacy of 111 lumens per Watt; making it 46% brighter and 64% more efficient than Cree’s highest-performance XR-E LED, but with an 80% smaller footprint.

“Cree’s XLamp XP-G cool-white LEDs set a new standard for LED performance,” says David Chow, president of 4Sevens LLC. “For our flashlights, the XLamp XP-G LED was a clear choice because of its high lumen output, unmatched efficacy and compact package size,” he adds.

Cree says that this level of performance can potentially reduce the number of LEDs required, as well as the size and cost of LED fixtures. High efficacy at lower current (up to 132lm/W typical at 350mA) can lower the total power requirement for a portable or solar lighting application, which can reduce the number of solar cells or batteries needed.

“We now deliver lighting-class efficacy at 1A drive current,” says Paul Thieken, Cree’s director of marketing, LED components. “In addition, we have begun offering limited samples of an S2 flux bin, providing up to 400 lumens at 1A,” he adds. Cree targets availability of XP-G neutral- and warm-white LED samples by the end of 2009.

The cool-white XP-G LED is available now with order codes up to 139 lumens minimum at 350mA and ANSI-compliant cool-white bins (correlated color temperatures of 5000-8300K).
