Projected LED Lumen Maintenance
Data references the extrapolated performance projections in a 40°C ambient, based
on 10,000 hours of LED testing (tested per IESNA LM-80-08 and projected per IESNA
TM-21-11).
To calculate LLF, use the lumen maintenance factor that corresponds to the desired number
of operating hours below. For other lumen maintenance values, contact factory.
