What lighting should I get for my 40g cube??

[The_Underwater_Gardener]

Hello all, I need advice on what lighting I should get for my tank I just started. It’s 21.5x21.5x21.5”. Would one AI Prime HD be okay? I’ve heard different things from different LFS. I was told that if I got one it would have to be on max all the time, would the fan be loud if that was the case? My budget would allow me to get two AI primes HD or one Ecotech xr15 Pro. What would be better? Could I get away with one AI prime HD?

I like the idea of 2 ai prime hds especially if you wanted to grow branching sps or acros. Otherwise the xr15 would be awesome on a LPS dominant tank. Dont think im saying the xr15 cant grow sps. One unit creates so much shadowing for branching sps, they just wouldn't grow the best without two units.
