I would say it depends.
If you had a 10x54w T5 you could hang them high enough to give you enough spread.
It also depends what kind of tank you want. Jam packed with SPS, a mixed reef, softies ect.
I run 6x54w over my 5 foot tank. I have no problems with a clam on the bottom or sps, and I also have shaded areas on the sides for other corals. Personally I like a bit of uneven light vs the perfectly lit tanks we often see, but again it depends what your goals are.
