There are LED lamps that run on 110 VAC.

Those have switching power supplies that should be avoided.


None of my 120 (or 220) volt LED lamps use a switching supply. They use a
simple series string with a rectifier, dropping resistor and filter cap.

That's fine but what do you think that diode is doing every 60Hz cycle?
It's switching on and off generating broadband noise. You know how some
white noise generator sources are made right?
