[ENDED] Group Buy: 46mm BLF SRK 7135 V2 - 32x 7135 Drivers - No Drama!

Is this the same driver in the SRK you sell, or an option for including in it?
I’d like this in that, count me as yes for one driver.

I usually modify the existing driver on the M6, but this will also fit once you file down the tabs (all lights will need these filed) and work to give you a regulated ~4A per LED and low moonlight.

Will this fit in the Ultrafire UF-T90?

Looks like the answer is no. Unknown00101 measured the driver you are asking about in the OP of this thread: Review: Quad XML2 Flooder [Similar design as a UF-T90], E-Switch in Handle (4x XML2, 1 - 4x 18650)

EDIT1: I forgot, that’s a ‘clone’ so it’s possible that a different clone/original/whatever might have a different diameter driver. I’d be a little surprised.

EDIT2: As an alternative it might be worth considering the 9-amp driver shown off by Old-Lumens in this thread: Maglite Twins - Build thread. Beam Shots are up The stock driver would need to remain in place as a contact board. I think that the 24x7135 driver might be able to be installed directly against the back of the LED shelf if care was taken with the wiring. New wiring holes might be required. In any case the heat from those 7135s must go somewhere.

About that measurement, that is the PCB which is soldered to a brass ring. The brass ring could be tossed aside and the driver itself be used as the primary contact between the retaining ring and the head. I haven't done the measurements yet, but I suspect it wouldn't be too difficult to accomplish.

I'm also not sure if the UF-T90 is set up this same way in the driver area. Been a while since I researched that one.

Ok. Thanks for the info. I didn’t think of a slave board

Ah, I’ve looked more closely at your pictures now. :zipper_mouth_face: I see now that the brass ring is adding quite a bit to the diameter of the driver. If I understand the pictures correctly the retaining ring is a separate piece - so even without the brass ring in place the driver could be tightly secured. Does that sound correct?

Yep, well mostly. The retaining ring is separate, but going based off the pics (been a long while since I had it apart), the threads may run out before the retaining ring can snug down onto the larger diameter PCB by itself. Might have to get a little creative here.

The quad xml2 handle is actually the light I mentioned earlier 'quad' that I was contemplating putting this fantastic driver in.

Put me down for 1, thanks

Thanks

Alright so is this what I want to beef up my thrunite tn32UT with 4 cells in series? Or is this more than just unsoldering and resoldering?

No. This will not work for that light. That light uses and needs a buck driver. Also, that light is 3S with a specialized carrier.

Please put me down for one.

So would this driver be an upgrade compared to what you put on the M6, or is it about the same?

(Edit - love the “No Drama” idea!)

I would say that this is very comparable to what I do to the M6 Mod.1: lower moonlight, about 4A per LED, and no disco modes. I think this is easier to install than what I do with the Mod.1.

Thanks, that’s helpful!

I’m in for 1
Thanx

I would like (2) Richard. Thanks!
