Where do you guys buy your X-ML drivers ?

LED Flashlights – General Info
1

I’m looking for a couple of good X-ML drivers to run the LED at 3-3.5 amps

One has to be a Buck driver (for use with 2x 18650) with 22mm diameter and the other has to be a Boost driver (single 18650) with 17mm diameter.

I would like something which is cheap but reliable.

So far I have found these

Are these companies good to deal with or would you recommend an alternative ?

Many thanks for your help, I’m still new to flashlights so still a bit green.

Thank you

The one from KD is also just a buck driver but works very well for single cell flashlights. KD is great to deal with, DX can be annoying. For infos on drivers, you might want to take a look here:

great list with a lot of info on most drivers.

Fasttech has this driver:

...listed as 2-3x Lithium 5-mode 3A @ 21mm, may be close enough for your use?

I've ordered this one, 20.5/21mm but haven't received it yet...

For the single 18650, I typically would use a Nanjg 105c but that would typically top out at 2.8 Amps. If you're good, you could solder an extra 7135 chip on there, but that's something I haven't tried yet. FastTech has a couple of varieties of the Nanjg drivers on their site as well:

Thanks guys

Keltex, would you say this one is any good ? does it matter that it’s not constant current ?

That's the one I have on order but I haven't received it yet. Once I get it in, I'm hoping to get it installed in my UniqueFire V2 clone and see how it compares to my DX no-mode-memory-annoying-strobe-model driver.

Ahh hehe okay thanks :smiley:
