Lighting question

[gradoj]

I would like something like:

the aqualight pro series canopy without paying the high price. If I were to purchase the bare ballasts and lights can a person buy an empty canopy that everything could be mounted in?

Would I save much money?

Any companies sell empty canopies that would accommodate all of this?

Any comments or threads talking about people doing this would be appreciated. TIA.
