One of the most dominate players in LED lighting, CREE has announced the XP-G LED that will soon be the industry’s “brightest and highest-efficiency lighting-class LED”. The cool white XP-G LED hits 132 lumen per watt when driven at 350mA, for total output of 139 lumens. For PAR demanding reefers, when driven at 1A (~3w) the XP-G hits 345 lumens. Cree states this is 37% brighter and over 50% more efficient than the widely used XR-E LED.

业界出名的LED生产厂家CREE最近宣布XP-G型号LED将会是本领域的一个特破，“更光，更高效的发光体LED”，这个新蕊达到132lumen流 量每瓦，工作在350ma毫安下，总输出139流明. 对于需要高光的珊瑚是一种福音，当在1A(~3W)达到345流明左右，比现在广泛使用的XR-E形号的LED光37%,省电50%

What is interesting is the XP-G’s footprint. It is 80% smaller than the XR-E! At 3.5mm x 3.5mm and 2.0mm tall. It is even smaller than the Luxeon Rebel. That said, the size of the actual chip has been increased, which can skew stats and comparisons to other LEDs like the XR-E.

更有趣的是，XP-G的体积只有XR-E的80%, 约3.5mm x 3.5mm x 2.0mm高，它甚至比Luxeon Rebel (飞利普生产的LED)还要小,此前曾宣称比XR-E要小的竞争性产品.

Cree showed off the XP-G last month at Lightfair International 2009 in New York City, where they used XP-Gs in an LR6 prototype downlighting fixture. The prototype uses a mix of yellow and red LEDs, consuming just 6.5w of electricity while emitting 665 lumens (102 lm/W) with a power factor greater than 0.9. The color temperature is 3,500K (92 CRI) making it a no-go for reefs, but the XP-G shows promise for both household and aquarium specific lighting.

CREE在上一个月的在纽约的“世界光电子展会”展示了XP-G,他们将XP-G置于LR6 prototype 顶棚射灯中,这个模形用了黄色和红色的LED,约6.5W产生665流明，(102流明/瓦),约0.9左右功率，色温为3500K,当然啦，这个色温并不适合两天，但CREE已经承诺将会为家用和水族用提供XP-G形号的LED

Chief technologist for CREE LED Lighting Gerry Nagley said, “By using the latest Cree LEDs, the XLamp® XP-G, we were able to achieve this great efficiency…We continue to push the envelope with LED technology—because consumers deserve high-quality light without toxic mercury or wasted energy.” Ouch, nice jab at the CFLs. The XP-G LED is expected to be available in the third quarter of this year.

CREE LED 首席技术总监Gerry Nagley说到”使用最新技术的LED XLamp® XP-G,,我们可以得到更高效的光源，并且绝对环保(没有水银)，同时更节省能源. XP-G将会在本年第三季度面市
