Last year I bought 20 fluorescent fixtures for use in the garage and shop. They were the economical workshop fixture available at Home Depot for $9. They use a SunPark SL15 electronic ballast. I have had several of the ballasts fail. The problem always seems to be two resistors, a .22 ohm and a 2.2 ohm. I was wondering if anyone else has bought any of these fixtures and had the same problem and done any experimenting on the ballasts to see if they can be resurrected. A new ballast is $6.50 so not really economical to replace in an $9 fixture, but if it's just two resistors, I would happily replace them.
