I even hung some #31 cores on the lamps themselves (which helped a little) and on the Romex feeding the fixture.
I don't have a good handle on RFI from fluorescents, but there are (at least) two mechanisms. One is radiation from the lamps themselves, and that can be reduced by shielding (a screen that makes a good connection to a mechanical reflector/enclosure, if there is one. The other is trash generated by the ballast ("modern ones, I believe, have the same issues as switching power supplies, and the trash is radiated by the AC wiring.
The RFI reflector might be a good resource for more. 73, Jim K9YC _________________ Topband Reflector Archives - http://www.contesting.com/_topband
