I found at my workplace (a hospital) trashy QRM/N from newly installed
flourescent lights had to be eminating from the switching power
supplies....they were very bad ! (preventing some equipment even operating
in our OR's !!!)
We had to go back to traditional ballasts. On a Spectrum Analyzer, the junk
was from DC to DAYLIGHT as they say.

This weekend I discovered noise from a set of 8 foot long fixtures.
What's the usual source, ballast controller, the bulb itself or ?. And
the best plan of attack (other than turning out the lights).
