Specification

Lumen values are from photometric tests performed in accordance with IESNA LM-79-08. Data is considered to be representative
of the configurations shown, within the tolerances allowed by Lighting Facts. Actual performance may differ as a result of end-
user environment and application.

Lumen Output
Use these factors to determine relative lumen output for average ambient temperatures
from 0-40°C (32-104°F).

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.
