I have a commercial customer who has a gym with F96T12 2 lamp fixtures in it. We replaced all the lamps with F96 T 12 DX Alto lamps ( commonly called daylight) and the old magnetic ballasts started going out. We replaced them with the new electronic ballasts and they are burning out. We checked our voltage and had 110v-113v. Will the electronic ballasts not operate on the lower voltage like the magnetic ballasts or do I need to look for another problem?
