Cree Inc. has released the XLamp XP-G LED in warm- and neutral-white color temperatures (2600K to 5000K CCT). The new XP-G LEDs extend the company's level of light output and efficacy across the white color spectrum, driving general lighting applications such as LED replacement lamps, outdoor area and commercial luminaires.

The warm white (3000K) XLamp XP-G provides up to 114 lumens and 109 lumens per watt at 350mA. Driven at 1A, the XP-G warm-white produces up to 285 lumens at 84 lumens per watt, which is 4x the light output than the highest available XLamp XR-E warm-white LED at equal efficacy.

The neutral-white (4000K) XLamp XP-G provides up to 139 lumens and 132 lumens per watt at 350mA.

Driven at 1.5A, the XP-G neutral-white produces up to 463 lumens, which is 4x the light output of the XLamp XR-E cool-white LED at equal efficacy.

"These new XP-G LEDs can enable LED lighting products that not only meet but exceed the current ENERGY STAR luminaire and lamp requirements. Cree is accelerating the LED lighting revolution by pushing through performance milestones," said Paul Thieken, Cree, director of marketing, LED components.

XP-G LEDs deliver high efficacy at high current, potentially reducing the required number of LEDs, as well as the size and cost of LED fixtures. Neutral-white and warm-white XP-G LEDs are commercially available now in the industry's smallest ANSI-based chromaticity bins.
