Need 27mm 2S, 6V output driver.

In years past, I would have just built one of the many drivers out there. But, I am having major eye problems and can barely swap and LED or install new wires. I really need a couple 27mm 2S, 6V out drivers for XHP-70 lights, they are Trustfire T62’s. I might be able to stack a driver on a backer, but not sure. I want to eliminate the the stock blinky modes and get just a little more out of the light.

So, anyone know of a decent 27mm driver for sale?

Thanks Matt

And I’d like a good option in 30mm. MtnE has a L6 fet-only driver but it’s impossible to get any sort of low modes or real regulation out of it.
