LED for a standard 90 gallon

[Restless10101]

Hey everyone.

Had a quick question on LED's and was hoping to get some help. I have a standard 90 gallon, 48 x 18 and 24 inches deep, and was thinking of switching to LED. Currently I am running a 6 bulb T5 Tek light, and I am happy with the results. But it's just about time to change the bulbs, and before I spend the money on new bulbs, I thought I would explore my options.

I am leaning towards Kessil, mainly because they have a freshwater option that I really like. If I need to buy a controller for my freshwater system, I might as well buy Kessil lights for my reef tank as well. Save me buying an extra controller.

Anyways the main question I have is, will 2 of the a160w be enough for my aquarium? Or do I need 2 a360w? Or is there a way to get 1 a360w to cover the entire 48 x 18 area?

Thanks for the help
