What size tank can I light with 4 XR-15s?

[biokeeper]

Looking to keep a mixed reef and I would like the option of keeping a decent amount of sps in the future. What would be the largest size tank that 4 XR-15s could meet these needs?

60*18 would do well. No more than 20-22" deep

You must already have the lights and are getting a tank to match?

Brs had a video about them, seemed to indicate they could light a 120. Maybe give that a look.

Yep.

Thanks. I thought I saw one and finally found it. It was 4 XR-15s over a 120g (48x24x24) so it looks like that will be what I go with!

I use two hydra 32s for my 120 48x24
I thought the radions were stronger so I figured you could light up a 6 footer with 4 of them.

4x2 120 gallon is a great tank. There are also some tank manufacturers that have 5x2 150s. At 5 foot, each light would cover 15" each, which is pretty reasonable. I wouldn't light more than that with 4 XR15s.

With 2 foot back to front, you might not keep Acros happy all the way to the back and front glass, but most people aren't doing that anyway.

That being said, I would get the tank that has the dimensions you want, and if you have to buy an extra light...so be it.
