Are these the small curly flourescents, about 13 watts sometimes selling
in some dollar stores?
I'm using a few of these and they seem to have a range of about 10 feet,
causing quite a bit of hum on the SW bands.

Gosh. All my antennas are outside. There's so much crap coming up
the power lines from outside I wouldn't think of using an antenna that
wasn't at least 10 feet from the house.

My antenna is outside also with shielded into the house. The interference
from one bulb is very bad.

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.

I had a problem with a 175 watt HID, but that thing was never intended
for residential use (I ultimately fixed it by building a 2 section
low pass filter between the line cord and the ballast assembly). It
had a cutoff at about 500Khz to keep the cap and inductor sizes
reasonable.
