The Cree XM-L Star LED is the industry?s highest performance, single-die white lighting-class LED. XLamp XM-L is 20% more efficient than XLamp XP-G at the same current, and can deliver 1000 lumens with 100 lumens per Watt efficacy. The XLamp XM-L Star LED offers Cree?s industry-leading features: wide viewing angle, symmetrical package, unlimited floor life and electrically neutral thermal path. The XM-L is re-flowed onto the LUXdrive Pixus Star board, which provides an easy to use XM-L LED that is electrically isolated.
XLamp XM-L LEDs can enable LED light into new applications that require tens of thousands of lumens, such as high bay and high-output area lighting. XM-L is also the ideal choice for lighting applications where high light output and maximum efficacy are required, such as LED light bulbs, outdoor lighting, portable lighting, indoor lighting and solar-powered lighting.

Average Lumen Maintenance Characteristics Cree currently recommends a maximum drive current of 1500 mA for XLamp XM-L white in designs seeking the ENERGY STAR* 35,000 hour lifetime rating (â¥ 94.1% luminous flux @ 6000 hours) or 25,000-hour lifetime rating (â¥ 91.8% luminous flux @ 6000 hours).
Please read the XLamp Long-Term Lumen Maintenance application note for more details on Creeâ™s lumen maintenance testing and forecasting. Please read the XLamp Thermal Management application note for details on how thermal design, ambient temperature, and drive current affect the LED junction temperature.
* These lifetime ratings are based on the current ENERGY STAR Solid State Lighting Luminaires V1.1 (December 12, 2008) and ENERGY STAR Integral LED Lamps V1.0 (December 3, 2009) lumen maintenance criteria.
