Perhaps it is not "energy-saving" dimmers in general that are RFI
generators but simply the particular ones you used.

When we completely rewired our home last year, state code required that
we use "energy saving" lights and dimmers. Our hall dimmer/light
combination gave off horrible RFI. After the final inspection, the
dimmer was replaced with a regular on/off switch and the RFI vanished.
No problem with the LED lights that stayed. But, our government (state,
federal, local) knows what is best for us, here in the Land of the Free.

I may have made an unwarranted conclusion, but I assumed the LED were
substituted for halogen without any other changes. I will see if I can
get a clarification on that point. Would a change in bulb types make
any difference in the RFI being generated?

It's not the LEDs, it's the wires (antennas) connected to the
switching power supply for the LEDs. This should come as no surprise
to any ham -- switching power supplies are generators of RF trash,
that puts RF current on those wires, and like any other antenna,
those wires radiate the trash.
Thank you VERY much for posting details of part numbers and vendors
for the bad products.
