Got bored and thought I could improve this light
Took it apart and swapped in a nangj 101 single mode 1400ma driver. Shield I had it apart gave it the gorxh treatment. I can not say that it came out any brighter though....looks more fun.
If its not as bright as you expected it may be a crook earth or switch. You can bypass the switch to see if it makes any difference. I hope you dont mind but here is your picture.
The pic was not working with me last night. I will check that and see
The donor driver I used seemed to have only 2 of the 4 7135’s working. Swapped it out with another and it is pulling 1.3 amps i believe the light has an XP-E
