Yuck. Sounds like a great way to pay Perfecto some $$$. <rant> Why is it that the
american market gets lighting after the rest of the world if at all?  </rant>

Anyway, I think I'll stick with T8s, but I'd like to get some recommendations for my 55
gallon for medium to high light plants.

1) Should I use 3 or 4 bulbs? (I was thinking of using 4 bulbs with two ballasts, each
on a separate timer).
2) Can anyone recommend some bulbs they've had good luck with that would be great for
plants and have a light balance that would be pleasing to the eye? I realize that some
combination might be my best bet.
3) Would any ballast with a power factor > 1 or 1.1 be fine?

Much thanks.
