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
specicationsfortheproducts.Calculatedvaluesareprovidedforinformationalpurposesonlyandarenotintendedas
specications.
Lumen Maintenance
Cree now uses standardized IES LM-80-08 and TM-21-11 methods for collecting long-term data and extrapolating LED
lumenmaintenance.ForinformationonthespecicLM-80datasetsavailableforthisLED,refertothepublicLM-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.
