I have been trying to find a way to light my work bench for
a few minutes, when I have service calls and need light. A
dome light from a camper works fine, but draws a lot of 12
volt. Too much to run on two carbon zinc lantern batteries.
Runs for a while on alkaline lantern batteries, but
expensive. Used to run it off a battery booster pack, but
the internal cell went dead.

Fluorescent lights don't work when it's cold.

Either I need more amps, or a LED set up of some kind. I
havn't found the right answer, yet.

Might have to rig it into the starting battery, in the front
of the van.

Something will come to mind, I'm sure.


Fluorescents work after warm up, and some are made to work faster in the
cold.

I would probably wire up some Cree warm white LEDs. The ones with 3 LEDs
have over 500 lumens each, and those are about $ 17. A series of the
cheaper $7 ones are good to spread out light. One working at 3 watts, with
heat sink is very bright at short distance, and you buy different angle
lens depending on app.
That's over 100 lumens.

Oh my, Coleman lantern. That harsh glaring bluish light. I hate any led
like that.
The Cree warm whites will please you.

I use led supply.
