New Cree XLamp® LED Performance Breakthrough Delivers Both High Efficacy & High Color Rendering

DURHAM, N.C., November 1, 2010 — Cree, Inc. (Nasdaq: CREE), a market leader in LED lighting, announces the addition of 80, 85 and 90 color rendering index (CRI) options to its XLamp® XP-G and XP-E warm-white LEDs. Many lighting applications, such as retail, medical and architectural, require high color accuracy to properly render object colors.

With previous-generation high-CRI white LEDs, increasing color quality meant decreasing efficacy. Thanks to the new high-CRI XP-G and XP-E, luminaire and fixture designers can have both.

“High CRI is a must for certain applications that require a high quality of the light—but at the same time, we cannot forget about the system efficacy,” said Massimo Santinon, brand manager i-Led, Linea Light s.r.l. “The new XLamp XP-E and XP-G with high CRI are the perfect combination we were waiting for that will allow us to address new markets.”

“Lighting applications require specific performance characteristics, and Cree’s XLamp LED family delivers products optimized for these individual applications,” said Paul Thieken, Cree director of marketing, LED components. “Our high-CRI XLamp LEDs can deliver light quality comparable to halogen with better efficacy than fluorescents. And Cree’s lighting-class LEDs are proven to be one of the world’s most-efficient light sources, which can enable more-economical designs and applications.”

The new high-CRI XP-G is available with luminous flux of up to 107 lumens at 350 mA in warm white (3000 K), providing efficacy of 102 lumens per watt. Using this new XP-G, LED lamp designers can create systems that are 70 percent more efficient than a traditional halogen PAR38 lamp and deliver similar high color rendering.

High-CRI XP-G and XP-E LEDs are similar to standard XP-G and XP-E LEDs, respectively, and may work in existing systems without any redesign. Just as with the standard XP-G and XP-E, the new LEDs have LM-80 data approved by ENERGY STAR®, are UL-recognized components under UL 8750 (E326295), and feature excellent thermal-management properties.

High-CRI XP-G and XP-E LEDs are available now in sample and production quantities with standard lead times. To locate a distributor, please visit www.cree.com/buyxlamp.

新的LED显色性应该有进步了，不错

对于XP-E 3000K的暖白Q4已经算不错了，自然白也才Q55C，对于XP-G Q4确实级别有点低了，不过显色指数90已经很厉害了

没看懂

你以为都象国内厂商炯炯又神地吹自己已经CRI达到95,暖白效率120LM/W

不错了白光LED是光色越黄光效就越低的

光辉神 发表于 2010-11-1 23:31

有XPG的Q4卖了？楼猪PM个？

muscel 发表于 2010-11-1 23:39

可以了

暖白的亮度不能和正白比。

muscel 发表于 2010-11-1 23:40

暖白是比较特殊的

喜欢的会很喜欢，不喜欢的会很不喜欢。

不是越亮就越好 产品得有对应使用方向

KAMIYU 发表于 2010-11-2 00:28

3K太黄了，4K上下最好，亮度也够。

散货或DIY商还是卖R5 3C。现在只关心XML，其他都无视，玩腻了。
