Yep i have done a lot with high powered LEDs and for long life you need 2 things constant current and good cooling ( heat sink).Nice job on the torch...
I agree with what you say about welding but i am just self taught and had some really bad welds 30 years ago but they never failed. The welding this chap has done is plenty strong enough but still good advice from you.
That is excellent, looks the part
This is what i was thinking, good project just needs a 18v panel. Nice job.
