Verification Method

The test method is designed to address the lumen maintenance of LED luminaires at a specific ambient temperature. The lumen maintenance is defined as the time when light output of half the product population has fallen below 70% of average initial light output for any reason. Projected lumen maintenance is based on LM-80 data of the LED module, driver reliability data in specification sheet and endurance testing.
