that would bring you to 560 true watts in a 4x4. Tsw 2000 and auto cobs is 410. Your call there. autos need less and these lights getting brighter. Just going forward if I was to upgrade from 2x4 to 4x4 with Mars gear I'd run 500 minimum in the tent. Just my opinion..Tsw 3000 AND the 2 autocobs that I already have?
