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.
