NOTES
Lumen Maintenance Projections
Based on internal long-term reliability testing, Cree projects royal blue, blue, green and white XLamp XP-E LEDs to
maintain an average of 70% lumen maintenance after 50,000 hours, provided the LED junction temperature is main-
tained at or below 135°C and the LED is operated with a constant current of up to 700 mA.
Cree currently recommends a maximum drive current of 700 mA for XLamp XP-E white in designs seeking the ENERGY
STAR* 35,000 hour lifetime rating (≥ 94.1% luminous flux @ 6000 hours) or 25,000 hour lifetime rating (≥ 91.8% lu-
minous flux @ 6000 hours).
Please read the XLamp Long-Term Lumen Maintenance 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.
Moisture Sensitivity
In testing, Cree has found XLamp XP-C & XP-E LEDs to have unlimited floor life in conditions ≤30ºC / 85% relative hu-
midity (RH). Moisture testing included a 168 hour soak at 85ºC / 85% RH followed by 3 reflow cycles, with visual and
electrical inspections at each stage.
RoHS Compliance
The levels of environmentally sensitive, persistent biologically toxic (PBT), persistent organic pollutants (POP), or other-
wise restricted materials in this product are below the maximum concentration values (also referred to as the threshold
limits) permitted for such substances, or are used in an exempted application, in accordance with EU Directive 2002/95/
EC on the restriction of the use of certain hazardous substances in electrical and electronic equipment (RoHS), as
amended through April 21, 2006.
Vision Advisory Claim
Users should be cautioned not to stare at the light of this LED product. The bright light can damage the eye.
