Here's 2 cents from a newbi in 6x6 but old timer in work boats and fishing gear for my fishing boat I use led lights from superbrightleds.com they have a assortment of high output led lights that are low wattage we use the rgb lights for the general lighting on the deck for working at night. The reason is so we don't need 4 batteries to run the electronics and lights Hope this is some help.
