I would put 8 of them on that tank if you want good light coverage end to end front to back.I have a Red Sea 350 that’s 4ft long and about 20” wide. Is 2x 16hd prime enough for softies and LPS? Is 3 over kill ?

I had one on a 16g cube and was limited to what I could keep on the sides. They are really good for a 12x12 area though.
Thanks I might just go with 3I have a 4’ tank that originally had 2 prime 16 hd lights. They did ok but once I added a 3rd I could tell a big difference. I eventually bought a par meter and was only managing a max of about 250 at the top of my rocks using mostly blues with just 14% of whites. I just upgraded last week to a reefbreeders 48 photon v2+. Couldn’t be happier with the spread and better par. I’m going to use the primes over a smaller tank with softies and inverts. They are good lights but you need several if you end up with more demanding corals
