3xU2

What flashlight host can this be placed into? The PCB appears to be 34mm in diameter.

there are others, but i'd say this is about as good of a mod as you'll find

I did a mag mod with one of these when they first came out. Since then I've cut the host back to a 1D size, and use it quite often at work.

I've never seen that mod. That looks really cool.

@dthrckt

That looks like a good 3xU2 host candidate.

My current project involves swapping out the driver on my Beamtech BT4000. I'm not doing it. I lack the skills. Sending this out on Monday. I'll update BLF on this project.

lack the skills? you could just try anyway, and 'brick' stuff until you have them, that's what I did. Actually...to be honest, I'm still doing that lol

I'll look forward to BT4000 results - so far that looks like a great mod host.

And I did a custom bike light with it :)
