To test and record the optical and electrical maintenance for a single LED or LED module, the LEDLM-80PL System for Testing LED Lumen Aging and Maintenance created in accordance with IES-LM-80 and TM-21. The software is based on the Arrhenius model and TM-21 to calculate the LED life. A GDJW/GW Series High-Temperature Chamber and a DC12010 DC Power Source are required for the LEDLM-80PL to function. The IES LM-84 and TM-28-compliant LEDLM-84PL LED Lumen Maintenance and Aging Life Test System is used to test and record the optical and electrical maintenance for LED luminaires.
