Radion Xr30w or Xr15w

[danielvaldivia9]

I have a 55 gallon mixed reef tank and currently using a normal t5 fixture. I have been running it now for about two years but now I want to upgrade to led's.

For my tank should I do one Xr30w or two Xr15w? Or what other lights do you guys recommend?

Depending on the amount you want to spend. I use XR15's with t5 supplement. IMO XR30's would get more coverage but may be a bit over kill.
