Get a different RF ground for your antenna. The random wire is 1/2 of your
antenna, the other half is the AC ground wire of your house.
I would be surprised if the lamp is your only RFI problem. Your house must
have RF all through it.
A RF ground is not a ground rod. I would run the ground wire (of the tuner)
to the ground (soil) out side and then run radials out from it on the ground
(dirt). I wouldn't use the ground lug on the radio, I would put an RF choke
between the tuner and radio. (On the second floor you won't find a RF ground
for your radio)
Will this stop the problem with the lamp? Maybe, maybe not, but using the
house wiring for your antenna is asking for RFI problems.
