Also thinking of getting these lights on a 120g 24x24x48 with plastic center brace - planning to put 4 in a canopy (oak) - will order a custom canopy - issue is, how high to have the canopy - standard is around 9", but could increase that. Currently have 2 x 400 Ushio 6500k and 4 x 4" actinic VHO, so I think I probably need 4 modules. Any comments/recommendations appreciated. This is a reef with predominantly acro.
