NOTES
Measurements
The luminous ux, radiant power, chromaticity and CRI measurements in this document are binning specications
only and solely represent product measurements as of the date of shipment. These measurements will change over
time based on a number of factors that are not within Cree’s control and are not intended or provided as operational
specicationsfortheproducts.Calculatedvaluesareprovidedforinformationalpurposesonlyandarenotintendedas
specications.
Lumen Maintenance
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specicLM-80datasetsavailableforthisLED,refertothepublicLM-80
results document.
Please read the Long-Term Lumen Maintenance application note for more details on Cree’s lumen maintenance testing
and forecasting. Please read the Thermal Management application note for details on how thermal design, ambient
temperature, and drive current affect the LED junction temperature.
Moisture Sensitivity
Cree recommends keeping XLamp LEDs in the provided, resealable moisture-barrier packaging (MBP) until immediately
prior to soldering. Unopened MBPs that contain XLamp LEDs do not need special storage for moisture sensitivity.
OncetheMBPisopened,XLampXQ-BLEDsmaybestoredasMSL1perJEDECJ-STD-033,meaningtheyhaveunlimited
oorlifeinconditionsof≤30ºC/85%relativehumidity(RH).Regardlessofstoragecondition,Creerecommendssealing
any unsoldered LEDs in the original MBP.
