Did I overdo it?

just modified the original driver of my TR-J18. I now got 2A to the LED’s and 15A on the tailcap
It got extremely bright! it totally outshines my SRK’s (was a bit dimmer originally)
and it defomed the spring mounted on the driver in a few secs :~ guess the switch is the next to go

Yeah now you need to beef up the parts that handle current, haha.

THough I think maybe going down a little might be good for longevity

I recommend to add a piece of wire to the spring or instead of it…

For sure add some wire to the springs. It sounds awesome. If mine was driven that hard, I would have kept it.

Yep, just add some desoldering braid to all of the springs.

Hey, can anyone of you tell or take a look out of your tr-j18’s that is it possible to rewire the leds? I’m planning to also mod it’s lighthead to be a part of my diving light. Only that I would rewire the leds to be in series and drive it with this driver

Should give huge amounts of light even under water.

Different light of course, but I just worked thru many of the same issues here: https://budgetlightforum.com/t/-/15387
