150 w metal halide on an oceanic 37 ???

[mmd]

i have the opportunity to buy a used aqua medic ocean light pendant 150 watts
-
i would put it over my oceanic 37 (24" long by 18" wide).
i would use either 14k or 20k bulbs
-
im currently using 4 t5's
-
i know its a bit low but i will not go higher than 150 watts as im keeping my tank low tech, i figured since my corals for the most part are in the center i would be ok
-
heres a pic of current set up w/t5
-
any comments, any pics of a similar layout ?
