All the comments are appreciated. Thanks! The lights are already installed, so no going backwards. It's generally only me here when I'm DXing AM, and sometimes another local DXer or two, so the plan will be to buy a few small regular portable lamps to use for reading or while DXing.
I will also do some experiments with a portable and also an extension of coax to see how far the QRN carries on AM. It is not affecting FM or TV, thankfully.

Anyway, I have tried 2 LED lamps and they both wiped out FM completely and messed up AM. The expensive Sylvania was worse than the WalMart Great Value. CFL lamps bad, but not as bad. CFL lamps....last longest burned base DOWN. CFL lamps being instant start do VERY poorly with frequent switching. Same as HF based linear fluorescents as well as magnetic instant start. Put them in an inclosed fixture and life will be substantially shorter. I expect LED lamps in an inclosed fixture will also have a reduced life expectancy as in an inclosed fixture there is heat. Heck, I found incandescent lamps in an inclosed fixture had a reduced life. My bedside radios now have incandescent lamps close in to read by. I just can't find a high enough lumen lamp for reading...... halogens get too hot. The ones that rate the same as 60 watts are not bright enough.
