NOTES
Moisture Sensitivity
In testing, Cree has found XLamp XM-L LEDs to have unlimited oor life in conditions ≤30ºC / 85% relative humidity
(RH). Moisture testing included a 168-hour soak at 85ºC / 85% RH followed by 3 reow cycles, with visual and electrical
inspections at each stage.
Vision Advisory Claim
WARNING. Do not look at exposed lamp in operation. Eye injury can result. For more information about LEDs and eye
safety, please refer to the Cree LED Eye Safety application note.
Lumen Maintenance Projections
For XLamp XM-L EZW (6V) Cree currently recommends a maximum drive current of 1000 mA in designs seeking the
ENERGY STAR* 35,000 hour lifetime rating (≥ 94.1% luminous ux @ 6000 hours) or 25,000-hour lifetime rating (≥
91.8% luminous ux @ 6000 hours). For XLamp XM-L EZW (12V) Cree currently recommends a maximum drive current
of 500 mA in designs seeking the ENERGY STAR* 35,000 hour lifetime rating (≥ 94.1% luminous ux @ 6000 hours) or
25,000-hour lifetime rating (≥ 91.8% luminous ux @ 6000 hours). Please consult the XLamp Long-Term Lumen Main-
tenance application note for more details on Cree’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.
