[RFI] The energy-saving LED bulb that switched off the radio

[David Robbins]

some LED bulbs use a switching power supply that is not well shielded.  i picked up a couple generic ones the last time i was in dayton, one of them is dead quiet and it still in use, the other one was all over hf and was sent to the arrl lab for testing.  Since these were generic ones, probably mail ordered directly from china for a really cheap price to stock this dealer's shelves, i would doubt that they had passed any type of fcc testing.
