B432IUNVHP-A UNIVERSAL Electronic Fluorescent (FL) 120V-277V 3-4 Lamp F32T8, F32T8ES, F32T8ES-25W, F28T8, F25T8, F17T8, F25T12, F40T8 Instant Start Ballast

Perfect! Installed works like a charm. Ordered 3 have 2 extra when needed.

It is good and low price. Work perfect.

Ballast performs well. Installation made difficult by short leads. Had to splice lines to reach the lamp holders. Inadequate for a 4 lamp ballast.

Works perfectly. No complaints on this

Was what I expected
