Two more questions to ask when comparing ballasts:
1. Will it trip my gfi? Most newer all-electronic ballasts will. So you
lose the protection of your gfi.
2. Will it cause a lot of rfi? Most ballasts will. It is pretty hard
to suppress without building an all metal hood (possibly with a plastic or
wood overlay).
These are the two problems I alluded to in my "dream" hood.
