Requirements
Light source life requirements: all
luminaires
The LeD package(s) / LeD module(s) / LeD array(s), including those incorporated into LeD light engines or
GU24 based integrated LeD lamps, shall meet the following L70 lumen maintenance life values (refer to Lumen
maintenance requirements in the next section):
• 25,000 hours for residential grade indoor luminaires
• 35,000 hours for residential grade outdoor luminaires
• 35,000 hours for commercial grade luminaires
Lumen maintenance life projection claims in excess of the above requirements shall be substantiated with a
Tm-21 lumen maintenance life projection report.
