I got mine from http://www.superbrightleds.com/moreinfo/dome-lights/led-round-dome-light-led-fixture-3w/1544/3514/ $10 a piece and 6 of them in my 3 place enclosed was plenty. I wired in a heater and battery system as well. It's very nice to be able to use the lights and heat when not hooked to the trailer.
Also I have wood walls, painted white with a gray painted floor. It REALLY brightened it up inside.
