You could consider a soup/soda can light 4x18650 SRK clone and replace the reflector and led with multiple quad or triple led boards with carclo optics. Some SRK lights have tripod thread mount, but they are harder to find.

thing is, it will be easyer to mod an actual rechargable warking light.
should be easyer to install charging port aswell, + i wont have to replace any reflectors,
working light should be all flud anyway.

all i need id a cheap waterproof mule so i can swap the internals.
like install a proper lithium charger modul inside, add some extra batteryes and maybe add some external USB port to charge phons.

For a real mule and WITHOUT tint shift, you should get Nichia Optisolis 3030 LEDs.
Very high CRI too, which is always nice.
I would recommend 4000K or warmer tinted.
You’ll just have to find a way to build them into that plastic Utorch.
You can solder them 4 at a time on XM-L LED boards and they can handle up to 1 Watt per LED.
I would recommend running them on 0.5 Watt or a bit more per LED, but i’m always a little conservative with the maximum current.

That Utorch has clear lenses, which may give you some prismatic tint shifting on the outer perimeter of the wide beam.
But you can frost them with sand paper or stick some diffuser film on them.

i need a mule recommendation, not what to put inside… thanks tho
