Changing the driver to TR-J12 should be quite straightforward. Some people say that they needed to sand the new driver a bit for it to fit, but others say it's direct fit. YMMV, I guess.. ;)
Strange thing happened yesterday, after having the flashlight two minutes with the maximum power…. suddenly she did a reset and I got the light at minimum and started to work right again , everything works fine now. :bigsmile:
Well I think I will buy the bord, just for safety.
