These are new 4' 2lamp fixtures with electronic ballasts and new T-8 lamps.
All fixtures are wired with new wiring and all are properly grounded. One customers fixtures are solidly mounted to the bottom of the floor joists in the basement. Another customers fixtures are hung from jack chain. In one instance the radio is on the same circuit.The other instance the radio is on a different circuit. The RFI (static) is on both AM and FM and it is full range on the freq selector. I do have questions out to the fixture rep. I have to go back and disassemble the fixture for ballast info.
They say it isn't supposed to happen, but I now have 4 installations ( after talking with other customers) with RFI. It will be interesting to see what the ballast people have to say.
