nice looking fixture, but why spend that much money for 150w mh bulbs in a tank that could/should use 250w? Not knowing what animals you want to keep, it's difficult to say for sure, but a 20" tall tank would not get intense lighting 1/2 way down and deeper with 150w mh's. Limitations on your animal possibilities when spending that much on a light fixture isn't optimizing the purchase...........imo.
