Cree Inc. reports the commercial availability of what the company claims as the industry's brightest and most efficient lighting-class LED. The XP-G LED can produce up to 367lm when driven at 1A, at a typical efficacy of 111lm/W. This makes it 46 per cent brighter and 64 per cent more efficient than the highest-performance XR-E LED. Plus it has an 80 per cent smaller footprint.

"Cree's XLamp XP-G cool white LEDs set a new standard for LED performance," said David Chow, president, 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."

This level of performance can potentially reduce the required number of LEDs, 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 amount of solar cells or batteries needed.

"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 400lm at 1A. We target availability of XP-G neutral and warm white LED samples by end of calendar 2009."

XP-G LEDs extend the leadership of Cree's lighting-class LED family, giving lighting designers a wide range of price and performance options that all share a common package footprint. The cool white XP-G LED is available now with order codes up to 139lm minimum at 350mA and ANSI-compliant cool white bins (5,000K-8,300K CCT).
