Review on 💡 Sylvania QTP2X32T8 UNV ISN SC B Fluorescent Tube by Cori Nance

Ballasts work fine but be aware of potential installation issues when replacing old larger ballasts. My 20 old T12 large magnetic ballasts were installed with two fixed screws aligned diagonally across the ballast. The holes on the narrower T8 ballasts are never far enough apart and I have to modify them with a file. It would be nice if the smaller ballasts had slots instead of holes on one end for easier fitting into older fixtures.
