I bought four Chinese 7 watt LED bulbs for the lights over the kitchen sink. They make a ton of radio noise from 3.5 to almost 10MHZ, they generate an S9 noise level across 40 meters. I have changed out all of the outdoor lights and almost all of the indoor lights to LED's and these are the only ones that generate any kind of noise. I guess I will have to replace them with the more expensive Phillips bulbs but I don't want these things. The weird thing is that I got almost all of the other LED bulbs from the same source.
