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 적분 구 of right size. The Aging and Light Attenuation Test system is applied to LEDs, LED module, LED bulb or other LED luminaries.
