I’m looking for 2 used but fully functional metal halide fixtures, 175w or 250w. Reflectors and Ballasts, bulbs are optional. I’ll pay cash or possibly trade hardware, fish, coral. thanks, John
I have a ballast that does 150w, 175w, and 250w. I found running my 250w bulbs was too much for the corals so I reduced it to 175w. My question is, will this harm the bulb that is supposed to be run at 250w but only getting 175w? It does change the color spectrum to a blue hue, which I like. Thanks.
