I think T12’s are going to be outlawed soon according to the newsletter I got from my elec CO OP. I started using T8’s (32w) years ago (0F start, seem to last much longer and the light output seems to be as good as the old T12s). But back to the question…T12 replacement ballasts will cost more than the fixture! And just something I heard…electronic ballast failure is often related to poor grounding of the fixture.
