I just want to clarify that you are considering using ALL VHO. Since some of the comments so far are refering to using VHO but those references are to using VHO as supplemental lighting.

I ran all VHO on a 120 tall tank before, 28" tall, and I could not keep SPS or clams.

I think VHO as supplemental lighting is fine but not as primary lighting unless it's soft coral only.

When I ran VHO I was also annoyed by how much space they took up...some pretty thick bulbs.
