I just put in a set of under cabinet halogen 20 watters ..... boy what a
bunch of crap RF wise. There is a 12 V supply that virtually eliminates
the
AM band and somewhat less on HF. This is at distance of 20 plus feet. Of
course they were made in Hang Chow ... no doubt somewhere east of
Ft.Wayne.

Tom, I have the same awful interference from new under-cabinet halogens.
Similar to your report, mine create terrible interference only through MF,
and limited hash on HF also. Mine are at least 40' away, and the station
power has its own load center/branch panel. The lamps are the switchable
2-level (not variable) and interference is present both settings.

I noticed a brand of halogens at Home Depot (now, of course) that state "No
Radio interference". Figures.

You have the same disorder I do - the stuff you need comes on the
market after you need it 8-} As to the interference, I'll go out on a
limb and say it's the power supply not the lamp - I've hooked up
halogen lamps directly to 12VDC and had no interference. Wall warts
are, as has been mentioned here many times, notorious for RF
interference.
