What kind of current is running through it, on what cells?

This one shouldn’t matter too much what cells are used because it’s acting as a buck driver to reduce the current down. But I’m not sure because other people have said it puts out more than the 4.8 amps that it states. The numbers on output say it is more. I don’t have any way of testing to check the actual amps. Of course I also put 20 gauge wire and mod the tailcap springs. The nice thing about this driver is that it’s really tough and because it’s set up to drive 3 emitters with 2 or 3 batteries it’s not being overworked at all in this light. Also with the nice sized pill and great thermal path it’s not going to stress anything and can be run on high for as long as you like, unlike some mods that should really only be run for a few minutes on high. A few guys have modded this driver to put even more amps but as far as I know they all end up killing emitters when they do, at least that is what has been reported to me. I think this is about maxed out for what this light can do and still get a light that can be safely run for extended times.

I have usually seen 4,3-4,5A mentioned on the forum from several people who have measured several of these drivers. I measured around 4,3-4,4A on mine. Resistance mods will not improve emitter current since its regulated.

It is true that modding the driver to 6-7A is not a healthy thing for a single LED since this driver seems to kill emitters at those currents. But the LIGHT can handle it. And an XM-l2 can handle it with the right driver.

If you want a safer setup, use two cells in parallel and a modified Qlite or something. It will still do 5A+ peak with decent cells. 4A+ for a good amount of time, but with low voltage protection, more mode options, better efficiency on high, etc..

When that is said. For 50$ shipped within the US, its a very nice thrower for the money. Im sure the owner will be very happy with it! Its a nice mod. :)
