My tank has a center brace so 3 wouldn't work, it was 2 or 4 and I wasn't sure I'd like them. If you have 2 braces 3 would work well and probably be a good choice. You will have more options with 360s. I strongly recommend their controller if you don't have another way to control them.
I have two braces on my tank, so three lights are probably the way to go.
