How many GHL mitras for my cube?

[nickguay]

Hi, I have a 93 gallon marineland cube and I currently have a kessil A350W over it and it's not quite enough lighting for it. I'm thinking about GHL Mitras and would I be happy with just one unit over my cube or would two be needed? It's 24 inches high and 30x30 in terms of footprint

If two are neeeded, two Ecotech Radions would cost me quite a bit less than 2 mitras is what I'm also considering...

Advices would be greatly appreciated

Thank you
