Lighting Facts Labels
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).
Lumen Ambient Temperature (LAT) Multipliers
Ambient Lumen Multiplier
0°C 32°F 1.03
10°C 50°F 1.01
20°C 68°F 1.00
25°C 77°F 1.00
30°C 86°F 0.99
40°C 104°F 0.98
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.
