Cree boosts XLamp XP-G LED efficiency to 140lm/W in production
LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has boosted its XLamp LED family with new levels of performance for its XLamp XP-G LEDs.
The cool-white XLamp XP-G provides brightness of up to 148 lumens and luminous efficiency of 141 lumens per watt, while the outdoor-white (4000K) delivers up to 139 lumens and 132 lumens per watt, and the warm-white (3000K) offers up to 122 lumens and 116 lumens per watt, all at a drive current of 350mA. The firm says that the XP-G can help lighting manufacturers to reduce system cost and complexity as well as making existing designs brighter and more efficient.
Cree says that, by leveraging the XP-G LED form factor, the increases in brightness and efficacy can shorten the LED fixture design cycle and improve customer time to market, with drop-in-ready performance enhancements. XP-G LEDs also have the longest projected lifetime data published, it is claimed.
Cree says that its XLamp XP-G LEDs are optimized for directional lighting, used in applications from street and area lighting to PAR replacement lamps to high-output flashlights. The firm says that it is also the first LED supplier to publish 10,000 hours of lifetime data, allowing users to project TM-21 reported lifetimes greater than 60,000 hours (or nearly seven years).
