Projected LED Lumen Maintenance
Data references the extrapolated performance projections for the TWP LED ALO (default
setting) platform in a 25°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.
