I'm using 100w Bright White and 100w Warm White (has yellow tint). One works/sees better in murky water.
Using a deer feeder 12v 7a/hr battery with a 600w step-up booster, boosting the voltage from 12v to 36v to operate the 100w leds, which is the max voltage. Also, a regular 12v boat/car battery will work just the same and you'll be able to work the lights all night w/o dimming.
If you use a step-up, whatever the wattage, make sure it has an adjustable current (amp) regulator and adjust it lower than the maximum current of the led rating (usually 3amps).

the 30 watt leds are 30v-36v and 1000ma so i got converters ordered from led supply.com since i run 36v trolling motor it should work out good.

where did you find the 12volt 100 watt chips? i really don't want to order them from china

They are not 12v 100w leds. They are 100w 30-36v 3amp (3000ma) max. And yes, they're from china, but they work as described and you cannot look directly in it when it's lit up. I guess you could, but I wouldn't recommend it, you'll see spots for about 3 minutes from just a split second look.

I do have some 12v 10w (1amp) leds. Suckers are super bright too.

I got them off ebay and took about 10 days to get here. Others took 14 days. I never buy "all" my leds from the same seller, that way I'm more apt to get them opposed to being lost in mail or at customs.

You'll need electronics safe 2-part water clear, high temp epoxy with a UV inhibitor (blocker).
I suggest a 600w step-up booster. Plenty enough to boost a 12v battery to 36v. It also has a current adjustment to set the current/amperage to match the led. You'll need a 100w LED cob or chip, I have the flat square cob led's. Thermal paste, aluminum heat sink (cheapest is from an old computer tower).
The epoxy will yellow in time due to heat, age and uv rays. I suggest you research the best one for your individual needs. If you want it to stay clear longer, it will depend on the quality of the epoxy you use.
I got all my parts from ebay except the epoxy. Again, research your needed epoxy as described in the 1st sentence. All epoxies are not the same.
