LEDs are low voltage devices, and the culprit is NOT the LEDs, but 
rather the SMPS (switch-mode power supply) used to convert the AC line 
voltage to the low DC voltage needed by the LEDs. OR, to be really 
cheap, only a step-down transformer driving the LEDs with no rectifier 
other than the LED itself.

BTW -- the ideal destination for posts like this and the one from W6LX 
is to the RFI reflector.
