I am planning to test some LEDs I bought from China. However, I only realized just now that the XHP70’s in the flashlight are commonly 6v version instead of 12v. It’s been a PITA to even find a 12v driver board, let alone finding the right size.
I’d prefer a 16mm format since most of my spare lights are using 16mm board.
Would be great if anyone here want to sell, or know where to get one.
You could use three Li ion batteries in series to direct drive the led. You need a contact board, leads & soldered spring where the battery positive connects. Depending on the length of the battery tube, you can use 18350s, 18500s, 18650s, 26350s, 26500s, 26650s. It'll be a hot light so high drain batteries may not be the best choice.
