I've used the green Kino Flo tubes, I felt like I got more green spill on my subject with them & went back to daylight tubes - though I don't have any empirical evidence to back that up. But, in any case, I didn't see a big difference in the quality of the chroma key background with green or daylight tubes, so it probably doesn't matter if the lights are green or not.
Having said that, those green Flolight kits look really nice, and the price isn't bad either.
