Different Voltage Test

AC Power source and voltage transformer helps our team run full operation tests under varying voltages and ensures that LED products perform at best even in excess voltage. The LED testing instrument also helps in running dimming test which is important to ascertain optimal LED performance.

Photometric Parameter Test

Integrating sphere helps in running wide range of tests including electrical performance test, photometric parameter test, and color parameter test. All the above tests play a important role in ensuring quality LED lights by taking into consideration forward voltage, reverse leakage current, power factor, colour rendering index, radiation flux, etc.

Goniophotometer for IES

Running photometric parameter test and electric performance test are important to set high LED lighting standards for testing. Both tests help us get light distribution, luminous efficiency, light beam angle, etc.
