Cree’s launches XLamp XP-G2 LEDs, boosting efficiency by 20% in XP footprint
LED chip, lamp and lighting fixture maker Cree Inc of Durham, NC, USA has launched the XLamp XP-G2 LED to deliver luminaire manufacturers up to 20% more lumens per watt and 2.5 times the lumens-per-dollar over the original XP-G LED. Cree says that the brighter, more efficient XP-G2 LED provides a boost in performance and enables manufacturers to use fewer LEDs to get the same brightness at lower cost or to increase brightness levels using the same LED count and power.
Characterized and binned at 85°C, the XP-G2 LED leverages the same footprint (3.45mm x 3.45mm) and is compatible optically with the original XP-G, providing drop-in-ready performance enhancements to shorten the LED fixture design cycle and improve customer time to market. The XP-G2 can enable a broad range of high-lumen applications, from indoor and outdoor to portable and lamp retrofits, says Cree.
“We have many designs using Cree's XLamp XP-G LED,” says William Weiss, partner and director of technology at LED lighting product maker MSi Solid State Lighting of Deerfield Beach, FL. “The new XP-G2 allows us to take full advantage of the benefits of Cree’s latest technology without any significant design changes, improving time-to-market,” he adds.
Built on Cree’s SC³ Technology Platform, the XP-G2 LEDs combine high light output, reliability and efficacy to deliver up to 151 lumens per watt at 350mA, 85°C or 165 lumens per watt at 350mA, 25°C in cool white (both at a color temperature of 6000K). In warm white (3000K), the XP-G2 LED delivers up to 133 lumens per watt at 350mA, 85°C or 145 lumens per watt at 350mA, 25°C. The SC³ Technology Platform leverages Cree's silicon carbide (SiC) technology, features advancements in LED chip architecture and phosphor, and showcases a new package.
Luminaire makers seeking ENERGY STAR qualification will have access to specification and performance data, including LM-80 reports, which can speed time to market, says Cree. XP-G2 LEDs are a ‘successor’ product to the original XP-G LED for LM-80 data - accelerating qualification of luminaires using just 3000 hours of LM-80 data, instead of the normal 6000 hours. The XP-G2 LED is also UL-recognized and features a level 4 rating.
