I have 2, Aqua Medic Ocean Light, 150 watt metal halide fixtures. I'm selling them for $70 each, or both for $120. They are used but in perfect working condition. Each come with their own ballast and lamp housing. The lamp uses double ended HQI Metal Halide Bulbs. Bulbs are included but are more than1 year old and should be replaced before use in a reef aquarium. Current spectrum may be adequate for growing indoor plants, but don't take my word for it. I'm a biologist, not an engineer...

I am also open to trade for a cube aquarium
