They're pretty good actually, I have a couple of the two lampers in the kitchen in use for around 4 years now. They replaced some NPF Universal ballasts which underdrove F40T12s.
Yeah, I've seen Lithiona vapor-tight fixtures come with these before...
Joseph, (did I spell your name correctly this time?) did you use these as replacement ballasts or did you replace the entire fixtures? How old were the Universals?
