For the par light, it takes 15 days in this strict testing, for the moving head light, it takes 40 days. This process can ensure the stable quality of the products,in every mass production, we also will choose 10% of the products and make sure they can pass this extreme aging testing!

We are always strict in aging testing, there are 5 times testing before leaving factory! For the par light, it takes 4 hours each time for final testing before sending into warehouse, for the moving head light, it takes 8 hours each time. Function in each channel of the light is checked carefully , if there is something wrong, it will be forwarded to the technical department and fixed, then be tested again to ensure the problem is solved.
