Why should a LED and the power conditioning circuits in most LED bulbs
push out any RF?

Because they tend to use switching power supplies using small high
frequency components.



Really? That may have been true for compact CFL low energy bulbs but
many of the LEDs seem to have a bridge rectifier, a current limiting
series capacitor and perhaps an addition smoothing capacitor, all
operating at a maximum of 50Hz. There is no voltage conversion necessary
as the LED arrays, connected in series operate at high (mains) voltages.
