How many XR30W fixtures

[dgwkpe]

I'm looking at getting 2 used xr30w LEDs (Gen1) with TIR lenses. I have 2 tanks that I could use them on and wanting some advice.

1st tank: 150 gallon (6' x 1.5' x 2.5') Reef tank, mostly lps, a few sps (not too concerned about sps). Will 2 of these be adequate to light this tank? currently has 2-32" led lights with no issues, but the xr30w are only 12".

2nd tank: 265 gallon (7' x 2' x 2.5') Fish Only tank. I will have a few shrooms, but mostly just a predator tank. Will 2 of these LED's put out enough light without too many shadows? I can hang them high if needed (how high would be enough?) Currently building this tank.

Thanks in advance for any advice.

no and no
not the gen ones anyways, even 2 gen 3 pros with wide angle lenses would be pushing it on the 6' tank at 2.5' depth, my recommendations would be a minimum of 3 gen 3's with the standard tir's on the 6', or 3 with wide angle lenses on the 7' FOWLR, 3 gen 1's with wide angles would probably work on the FOWLR tank beings you just need to illuminate it
