This system is designed for normal / accelerated aging, lumen maintenance measuring, lifetime evaluation and temperature characteristic testing for LED luminaires. The extrapolation of lifetime by programmable models is also available to estimate the lifetime of LED luminaires. It fully meets the America “ Energy Star” standard IES LM-82, LM-84 and other related standard.

• The design of the six temperature zone makes it possible for test in different temperatures simultaneously, greatly reducing the test time and improving test efficiency;
• It can monitor the light, color, electricity, temperature and other parameters of each light source in real time with high test accuracy.
• The buring position of the LED lamp can be base up or down according to the actual demand.
