    Thank you Michael. I will check that route out as well. I like "no muss no fuss"

    Have a look at this one here: http://www.mouser.com/Search/Refine....rd=588-rlsr50e

    It's the top one that's in stock. It will handle 120 watts which is what 24 amps converts to at 4 watts per bulb @ 5VDC for 300 of the critters.

    The resistance is slightly high though. Your resistance given the above is .20 ohms. The resistance of the rheostat is .5 ohms. It might not make too much of a difference. If so, tweak the voltage on the supply up a quarter to half a volt. You'll have a bit of loss anyway in the wiring.

    I measured the current draw for my overhead today, and it draw 13 ampere and the aft overhead draw 2,5 ampere. So I probably dont even need to modify my pwm cards to use this solution.

    Good news for me

    Would something like a 12/24V rotary DC dimmer switch as used on yachts be any good?

    Finished the wiring for my DC motor controller today, and the dimming works just fine

    Need to more testing before I can shout success. But if success, then I will write a detailed tutorial for this setup when time permits. Need to do some more testing over time. And not just a 15 minute run

    Little video of testing here
