According to the requirements of IESNA LM-80-2008, GB/T 24824, LB/T 001, the system is used to aged sorting, reliable, and accelerated lifetime test for LED modules and LED luminaires. The system can monitor and record the photometric parameters, electrical parameters and shell temperature in real time, to test the thermal performance and lumen maintenance ratio.

LATS-90 system consists of temperature stabilized chambers, power supply of testing LEDs, junction temperature detecting system, light measuring instruments,can record The light degeneration of each testing LED at specified powered current under ageing temperature. The lifetime of tested LEDs under operating temperature can be expected through light decay extrapolating and the lifetime accelerating model.
