Hello BLF.
I am have been wanting to build an LED spottie for a while and have finally gotten myself started.
I have read up a fair amount on the BLFGT - GT70 and enderman’s searchlight builds, I’m nowhere near that level but I’m having fun anyway.
I have been learning / reading and purchasing components as I go along, which has led me to ending up with some less than ideal solutions (ie: my 6v 10a step down). I am learning though. slowly.
my plan is to run the light on clamps to a car battery while hunting. about 13v.
The LED I have on hand is a 6v MT-G2.
mountain electronics do not have a driver that will supply over 6A.
I think im going to have to end up building my own driver.
anyone know of an off the shelf solution for 7 or 8 amps and up to 7 or 8 volts from 13v?
I’ll keep doing what I can and trying to learn on the fly.
Here’s what I have going at the moment:
EDIT:

$13 cpu heat sink and fan
and a bunch of little things like wire heat shrink, a switch and a fuse etc…. probably cost about $200 all up.
for tests i’m running off a 3s lipo, normally it will be plugged in to the cigarette lighter port in the car.
I was originally looking at buying one of these:
but i think my light is at least close in performance, probably brighter, maybe less throw.
All up im pretty stoked with the way it turned out.
