Lighting suggestions 36" X 15 x 15

[freezetyle]

I recently got a nuvo fusion 30l (36") and have been struggling with lighting choices. The tank currently has a single kessil a360 which obviously leaves a lot of dark areas in the tank. So I have been throwing around the idea of selling that and getting the following options.
1) 3 kessil a80-
Pros: I already have a controller, silent (big plus), nice shimmer, price
Cons: under powered? Need to build canopy as I want to contain pretty much all light spill due to wife complaints
2) 2 ai prime
Pro: controllable, high powered
Cons:noise, still need to build a canopy, might still get shading
3)ati 36"sunpower non dimmable
Pros: no canopy, can use t5/led bulbs, even coverage
Cons:too powerful for15" depth?

Any Suggestions?
