Lighting question

[kuatto]

This has probley been covered before,but is there a big differance between VHO and power compacts?The new tank will be set up as a reef but with just small fish and softies such as gsp,shrooms,etc.Once it has matured and become stable,I'll upgrade to mh and a few differant corals.
I was going to transfer everything from the 55,but don't want to disturbe the somewhat stable enviroment.
