Driver help

Hi,
Wondering if anyone knows where I can purchase one of these drivers. It’s a 32mm double board for 3 led’s and runs off 2 18650’s or 26650’s. High, medium and low is not a reduction in power to all three led’s but just turning each led off in turn.
I have contacted sites the sell this light ( TMART & DX) who dont respond to my request to see if they can sell me just the driver.
I have tried to search for the number on the board but again have come up with nothing.
If I can’t find the exact replacement, any ideas on a straight driver swap would be good.

What light is that driver used in?

What is wrong with the old one?

How hard do you want to drive the LEDs?

Sorry, been busy at work.

The light is a 3 led Tangspower. The Fenix TK45 Clone.

I only have one led working. Tested all LED’s on their own and they work fine. Tailcap also works, so must be the driver.

The LED’s, I think run at 2amps each.

How big is the driver compartment

Its quite large. I havent got the exact measurements but there is an internal ring built into the head so whatever driver I use will still need to be flat.

The 3T6 driver is able to drive 3 parallel LEDs with 4.5A stock and resistormodded with 6A. All that from two cells.
But it is not flat and not so straight at all…

Thanks. Yes I have a 3t6 and realised it wont fit. I also thought about a Dry driver but its too big.

The drivers for the light I have seem to be so difficult to come by. They still sell the light, so unless they are all old stock, which is possible as they dont seem to be that popular, surely I should be able to get a driver somewhere :_(
