Lighting Help!

[Elementality]

I've been doing quite a bit of reading and heard both positives / negatives for both T5 fixtures and LED fixtures. I'm in the midst of setting up a 75G Reef Tank (48"x18"x20") with Eurobracing (center brace) and was curious as to the best choice in lighting. Price point? Less than $1500.

I'm debating between the following:

Concerns for the above: Will the center brace of my tank alter the coverage enough to make the above not worth the money?

Concerns for the above: Will two units provide enough coverage for me tank?

They both equate to roughly the same price, however there are pro's and con's for each of them. Does anyone have any experience with the above lighting fixtures? Would two AI Sol Super Blue's provide enough coverage for my tank?

Any insight would be greatly appreciated!

Thanks,
