Decided to build a flashlight-Need a little help from the pro's

LED Flashlights – General Info
1

I would like to take a crack at building my own flashlight. I'm tired of buying cheap crap and throwing it away, and I can't afford to buy a quality one like I need. I would like a high brightness light so I have landed on the XHP70.2-N4-5K. I would like to install it in a UF-1405 Zoomie Flashlight Host because it loads 2x 26650 batteries. So I have never built a flashlight before and I was never a whiz at electronics so I don't know what driver or batteries I should get. I bought one of those cheap, 90,000-lumen flashlights, and after tiring of charging batteries all the time I decided to buy a couple of (what I assume are) high-quality batteries. They came from a vape shop. They're made by a company called Hohm Grown. The label says they're 4,244mAh and 41.1A (30.3A CDR). The second I turned on the flashlight it fried the emitter. I posted about it on BLF and it was suggested that the problem was the driver (on the flashlight I'm assuming).

So in conclusion, would this be a decent thrower/walk the dog in the country/fix a trailer on the side of the road flashlight? What driver and batteries should I get? I'll be buying it all from MTN Electronics.

Thanks,

Mike

I started building my own lights for that reason. Those zoomies are generally better than the cheap ones. Ithink that host takes a 16mm mcpcb 17mm driver. For xhp70.2 you need a boost driver for 1 cell or you could direct drive the 6v on 2S with a zenner modded driver but that would generate a lot of heat and zoomies don’t have the greatest heatsinking. I recommend something like a bost driver with a 6v emitter. Use good thermal paste.
