Do you know clearly how to test h7 bulb? if not, I would like to explain to you as below.

In my factory, I need to put h7 bulb into a big integrating sphere. The intergrating sphere connects computer and spectrometer.

Please note h7 bulb test are all in 13.2v that’s not in 12v.

When setting 13.2 in computer, all data of h7 bulb will be tested automaticly.

All of our h7 bulb will be tested at least 5 times before leaving factory.

In order to make you clearly how to test h7 bulb, I will show you our testing machines as bleow.
