Ok, so I'm about to order new bulbs for my outer orbit fixture and can't decide what I want to do. Currently, the fixture has 2x 150w Metal Halide's, 20k, which are new bulbs right before I bought it. I love the color of them, very very white, slight tint of blue. It also has 4 48" t5's with individual reflectors. Right now they are 4 460nm actinics, but I was thinking about only running 1, possibly 2 actinics, as I know actinic bulbs put out very little par. ...
