NOTES
Measurements
The luminous ux, radiant power, chromaticity and CRI measurements in this document are binning specications
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
specications for the products. Calculated values are provided for informational purposes only and are not intended as
specications.
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 specic 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 XM-L HVW 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.
UL Recognized Component
Level 4 enclosure consideration. The LED package or a portion thereof has been investigated as a re and electrical
enclosure per ANSI/UL 8750.
Vision Advisory
WARNING: Do not look at an exposed lamp in operation. Eye injury can result. For more information about LEDs and
eye safety, please refer to the LED Eye Safety application note.
