ECN Forum Forums Technical Discussion Electrical Theory and Applications Radio Interference and T8 Fluorescents Fixtures

I just ran into that problem last Summer. I installed some
T8 fluorescent fixtures in a kitchen. There was radio interference. I bought the fixtures at a local electrical supply house and assumed they would be OK to use. I pulled those fixtures and bought a couple more at Home Depot. These one's specified they were for residential use. Same problem!!
I called the ballast manufacturer for information. They said the ballast number has an "R" in it if it is for residential use. I checked them and sure enough there was an R in the number. He said some of the ballasts are defective. They sent me 2 new one's free of charge. Problem solved!
