Nice! I was tempted to do a 60" 8 bulb t5 fixture for my next tank build, but like you I love my halides so I may stick with them and do the same set up as yours.
Got them on all my tanks.. Amazing product, no regrets. Improve your reef, use reef brite strips. There are that good!
I'm curious if those are the "all blue" or the "blue white" XHO model?
