I was curious if anyone was using metal halide bulbs, or high pressure sodium lights in their large enclosures. I have 8x8x4 enclosure with natural light, and two 48" repti sun 5.0 bulbs. I also have two mercury vapor bulbs at 75 watts each. I do not use both vapor bulbs all the time. I don't have a cham in it right now but I will in a few months. I was considering buying one grow light for the cage.
they even make UVB ones.
