FET help

Hi guys i’m building a sst-90 flashlight using 4c cells probably DD i’m having trouble finding a decent switch capable of handling the 13+ amps ( i’m mounting the led directly to a big lump of copper :slight_smile: )
I’ve read that a FET is the way to go to allow me to use any (even the mag) switch to control the light, the problem is i have no idea what i’m looking for. I know how they work and how to wire it in but haven’t a clue what kind i need !!

any help would be much appreciated.

Not to change you idea or anything but instead of the fet would it not be easier to use 3 3A boards in a master slave configuration like Old Lumens did in his sst-90 shower head build.

I always thought regulated was better than DD to maintain a constant level of brightness.

True and i have done this with a tripple xml-u2 set up but i want more than 9 amps, ideally i would want a driver that could run the led at 9a and then be able to do direct drive ( turbo mode)

I like that idea. It would be cool if you could incorporate it into the switch. click for on, push partially from any position to get turbo.

It can me done but the guy who makes the light in question won’t sale the drivers u have to buy one of his lights :frowning:
