notes
lumen maintenance Projections
Cree now uses standardized IES LM?80?08 and TM?21?11 methods for collecting long?term data and extrapolating LED
lumen maintenance. For information on the specifc LM?80 data sets available for this LED, refer to the public LM?80
results document at www.cree.com/xlamp_app_notes/LM80_results.
please read the XLamp Long?Term Lumen Maintenance application note at www.cree.com/xlamp_app_notes/lumen_
maintenance for more details on Cree’s lumen maintenance testing and forecasting. Please read the XLamp Thermal
Management application note at www.cree.com/xlamp_app_notes/thermal_management for details on how thermal
design, ambient temperature, and drive current affect the LeD junction temperature.
moisture sensitivity
In testing, Cree has found XLamp Xp?C and Xp?E LEDs to have unlimited foor life in conditions ≤
30
oC/85% relative
humidity (RH). Moisture testing included a 168?hour soak at 85
oC/85% RH followed by 3 refow cycles, with visual and
electrical inspections at each stage.
Cree recommends keeping XLamp LeDs in their sealed moisture-barrier packaging until immediately prior to use. Cree
also recommends returning any unused LeDs to the resealable moisture-barrier bag and closing the bag immediately
after use.
