sure. now, you have your choice of LED
, or metal halide.
if i was going to use halides, i would get 3 of these. they are the best you can get in terms of reflectivity-
Lumen Bright 3 SE Mogul Base PENDANT by CoralVue* - AquaCave
and then 3 ballasts. i'd probably go with sunlight supply galaxy electronic ballasts. i would have said icecap for ballasts, but they just went out of business, and that can't be good for the warranty.
i don't know a whole lot about. i do know that you should have dimming capabilities, and the fixtures you choose should be backed up by actual PAR numbers, not just that they are "real bright", or make the corals "pop".
