Electronic Fluorescent ballast
I have several 4' flourescents in my basement workshop, all running of the same switch. Some are the newer electronic ballast, and some are the old transformer type ballasts. Both types call for the same bulb, but the electronic ballast seems to burn out the bulbs in a year. The bulbs in the old transformer type last 10 years or more. (One has bulbs that are 20 years old)! I've already spent more on replacement bulbs than the cost of the fixtures.
Does anyone know why this would be?
