Converting Reef to FOWLR

[Gizmo]

I've moved my coral's into my 70g 48" Tank with the clown fish. I moved my PFO 1200w Fixture onto that tank, only firing 2 of the 400w lights. Its lots of light and it looks like it will do well. BUT now my 260 is without light temporarily. What kind of light could you guys recommend for this tank? I was thinking 2 36" T5 6bulb Sunlight Supply Tek fixtures with Giesemann Bulbs (half actinic+ half aquablue+) Would that be enough light? Too much? Tank is 2.5' deep.

Thanks!
