The radio which was tuned to an FM station, had a lot of white noise and could not hear the station very well. I turned off the lights and the noise disappeared.  So be aware of this situation.  So much for meeting FCC emission specifications.

You might have to add a computer power supply line noise filter and a
coarse grounded screen (like 1/2" hardware cloth) over the fixture to
quiet it. Or an outside yagi for the radio with double shielded coax to
the radio.
