I already spoke to the thermal problem in an enclosed and insulated fixture.
More specifically on RFI. I have some LED bulbs, from Home Depot, that are nice RFI generators in the middle of the AM band. These propagate the noise on the wiring in my home, to the pole transformer, and to two street lights. From this wiring noise is radiated to my car radio, or any battery powered radio. An AC cord attached radio may also receive some of this noise via the AC cord (conducted vs radiated).
My Comcast cable box generates a great deal of conducted or radiated noise in the AM band. Phase shift dimmers (chopped sine wave) vs Variac dimmers produce AM radio noise.
