Well if you get the Blue+ bulbs they have fairly high output and can be used as stand alone bulbs, I run 2 blue+ and two UVL super actinic, and they're on by themselves longer than the metal halides and I'm getting great colors and growth it seems... of course there are 100s of other factors that could have happened as well.
Start thinking about how long you want your halides on... do you want to go the route of "most the day its bright" or "the sun is only really bright for a little bit" that should help you decide on the T5s
