125G in need of light upgrade...

[sc0rp_xiii]

I inherited this canopy when buying the 125G used:

It has a single 36" 6k 50/50 Coralife over a 72" tank with a separate blue LED strip for "moonlight." I have been looking at T5 lighting as I will be going with a FOWLR and maybe upgrading later to a few corals after the tank matures and I have more experience with it. The question I have is what scenario would be better:
1) a 72" fixture with 4x96W, Dual Daylight
6700K/10,000K and Dual Actinic
420nm/460nm with 6 lunar = 384 watts
2) (2) 36" fixtures with 4x39W, Dual Daylight
10,000k and Dual Actinic
460nm with 3 lunar = 156 watts each for a total of 312 watts
Any and all comments or suggestions are welcome to help me spend my $$$

I would go with this one
1) a 72" fixture with 4x96W, Dual Daylight
6700K/10,000K and Dual Actinic
420nm/460nm with 6 lunar = 384 watts
IMO. Match the fixture to the tank.

I understand what you are saying but will parts/bulbs/consumables be any cheaper or more readily available for the 36" fixtures?
