Cree maintains a tolerance of ±7% on flux and power measurements, ±0.005 on chromaticity (CCx, CCy) measurements and a
tolerance of ±2 on CRI measurements.
Minimum CRI for standard color temperatures 0E8, 27F, 27H, 0E7, 30F, 30H, 0E6, 35F, 35H is 80.
Minimum CRI for standard color temperatures 0E5, 40F, 40H, 0E3, 50F, 50H is 70.
Typical CRI for standard color temperatures 0E5, 40F, 40H, 0E3, 50F, 50H is 75.
Flux values @ 25 °C are calculated and for reference only.

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 specific 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/XRE_
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.
