Cree claims most energy-efficient neutral- and warm-white lighting-class LEDs

Cree Inc of Durham, NC, USA has announced the commercial availability of its XLamp XP-G LED in warm- and neutral-white correlated color temperatures (2600–5000K CCT). The new XP-G LEDs extend Cree’s highest 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 a drive current of 350mA, and up to 285lm and 84lm/W when driven at 1.0A (four times the output of the highest available XLamp XR-E warm-white LED at equal efficacy).

The neutral-white (4000K) XLamp XP-G provides up to 139lm and 132lm/W at 350mA, and up to 463lm driven at 1.5A (four times the output of the XLamp XR-E cool-white LED at equal efficacy).

Cree says that its XP-G LEDs’ high efficacy at high current can reduce the number of LEDs required, as well as the size and cost of LED fixtures. “The extremely high efficacy levels are enabling us to offer our Aimed Optics luminaires in a neutral color while maintaining the same pace-setting mounting-height-to-pole-spacing ratio and fitted target efficiency that we previously achieved with cool-white color temperatures,” comments Bob Fugerer, president of LED lighting firm Sunovia Energy Technologies Inc of Sarasota, FL, USA.

“These new XP-G LEDs can enable LED lighting products that not only meet but exceed the current ENERGY STAR luminaire and lamp requirements,” says Paul Thieken, Cree’s director of marketing, LED Components.

Neutral-white and warm-white XP-G LEDs are commercially available in the industry’s smallest ANSI-based chromaticity bins.
