Technically since the lamp is intended for household use, it should be
FCC Class B certified. If you can hear it from more than about 10
meters away, it probably is not Class B, and consequently probably
should be reported to the FCC.

Light bulbs are part 18 (Industrial/Scientific/Medical), not Part 15.
(At least that's what the GE brand ones said on the packaging). They
also said not to use it in a location where there are radios used for
emergency/safety services.

I had some pretty strange results. I'm using one of those 13 watt ones
in my bedside lamp, and the RFI (mostly) went away when I reworked my
power from a rats nest of extention cords to one power strip. Even though
the lamp is closer, electrically, to the shortwave, the interference is
much reduced.

So, interference may be related to the physically construction of the
power wiring.
