New single-chip LEDs XLamp XM-L 2 with 186 lumens per watt by Cree
The new XM-L 2 LED from Cree achieves a luminous efficacy of up to 186 lumens per watt at an operating current of 350 mA and is available for purchase from over MSC. This corresponds to a level of performance that has been achieved up to three years only under laboratory conditions. The new generation of LEDs based on the SC ³ Technology platform, offering at the same price of the XM-L twice as many lumens and 20 percent more lumens per watt. Thus, LED lighting manufacturers provide less expensive and lighter systems.
The new XM-L2 LEDs are designed for very-high-lumen applications such as indoor, high-bay and outdoor lighting. The high-performance XM-L2 LEDs are compatible with existing XM-L LED designs and leverage the 5 mm x 5 mm XM footprint – allowing customers to easily incorporate the XM-L2 LEDs into existing XM LED designs to shorten the fixture design cycle and improve time-to-market.
The XM-L2 LED offers the unique combination of very high efficacy and high drive currents, delivering an unprecedented 1198 lumens at 116 lumens-per-watt efficacy at 3 A. The XM-L2 is the eighth product built on Cree’s SC³ Technology platform. The innovative platform leverages Cree’s advanced silicon-carbide technology, features advancements in LED chip architecture and phosphor and boasts a new package design to deliver the most-advanced LED components in the industry.
Characterized at 85°C, the XM-L2 LED is available in 2700-K to 6200-K color temperatures and offers minimum CRI options of 80, 85 and 90. Additionally, since the XM-L2 LED is a successor product to XM-L LEDs, the application of ENERGY STAR® qualification requires only 3000 hours of XM-L2 LED LM-80 data, instead of the normal 6000 hours. The XM-L2 LED is also UL-recognized and features a level-4 rating.
