That aligns with the new knowledge I got at Dayton... All of these LED bulbs
are designed with universal switching power supplies built-in (100 to
240VAC) and we all know what that means... a SWITCHING power supply... think
RFI generator.

And I can imagine there is not a lot of attention paid to making them as
quiet as a HAM would want.
