When I reworked a radio station in the early '60's we installed the 
ballasts' in the hallway and we also installed the radio interference 
filters on them.  It was difficult to listen to our AM station with all the 
fluorescent light noise.  The filters sure cleaned up the radio reception.

After that I always spec'd Radio Interference filters in the fixtures in 
offices also.
