If you're just replacing an existing light fixture with a flouresent, it should be fine. The only major difference with the low voltage system is that the lights are controlled by relays in a box somewhere. Think of it like this:
All of the "light switches" (relays) are crammed together in a central box somewhere. The low-volt switches on the walls are like remote controls that "flip" the light switches for you. So on the actual light fixture side of things, there isn't much difference in the wiring compared to a regular line-voltage switching setup.
