How to measure the LED life time is a big question for the manufactory. LS822 aging and optical attenuation tester is developed according to LM-80. LS822 can record the Flux VS Time data and export Excel format. The professional LED design & research engineer can calculate the life after the data analysis.
Flux VS Time testing is required to work with the integrating sphere of right size. The Aging and Light Attenuation Test system is applied to LEDs, LED module, LED bulb or other LED luminaries.
