Need guidance.Sbt90.2 Build help. Need host and driver

Flashlight Modding and DIY Parts

I need some recommendations on a driver and host for a sbt90.2 build.

I would prefer something larger than the Nightwatch NI40L, I also would like to keep it single cell but am open to a 2S build aswell

It would be nice to run the auduril UI.

Thanks in advance

2S would need a buck driver since sbt90 is a 3v emitter. You’d be better off with 2P arrangement if you want multiple cells.

Ant 3V driver will run the sbt90, but for high performance Lexel makes nice drivers, so does Mountain electronics. Definitely want one with thermal management. For a host, anything that’s got good heatsinking. You’ll want a fairly large host for it. I don’t know if Nightwatch makes a host for it?

Well, you don’t need to build it yourself, all your wishes are available by the light built by Hank in the K1

I may just do one cell, seems easier.

Where can i check out the lexel drivers?

what about Dr. jones driver?

How hard is it to find a host with a electronic switch or to convert it to one?

Another choice is the Astrolux FT03S. It meets all your criteria. Larger than NI40, Anduril, single 26650/21700/18650

Wait, what?

All your criteria are suddenly changed?
Did you even look at the K1 (SBT90.2 Anduril, single 21700 cell, integrated USB-C charging?)

I wouldnt go for Astrolux, its inferior to the K1.

I like it !! Nice suggestion. :wink:

Sorry I may not have been very clear I waited to build a flashlight using the sbt90.2 as the Led and was looking for a driver and host.

Edit: Yes I have looked at the K1 and currently that is the only lights of Hanks that I don’t own. I’m sure eventually I will own one because it looks badass, but I’m just after a build being that i already have the led.

There are not going to be a lot of choices that make sense unless you already own the light. It has to have a (very) good heat path and suitable reflector.

Tossing both those points aside (cause it probably has a meager brass pill) put one in the brand new Convoy Z1 and tell us how it works out.

The thing is, you’ll need a decent host for a good price otherwise you’ll end up being more xpensive as buying new.

This led generate a lot of heat, so you need big, massive host to get the most from this led.
Otherwise you’ll finish with under driven, poor performing light.
