LED bulbs and radio interference

To day a customer came into our store asking if we were aware of radio interference generated from the new LED light bulbs. He claims he read such things on the Internet but did not know the source. I was not aware of any such problems and none of our product packaging indicates that LED lighting will cause interference similar to that of fluorescent lighting.
Can anybody comment or know if electronics can be affected by use of LED light bulbs?

Sounds like an old radio guy walked in on you!

Yes, LED bulbs do create a bit of RFI, at least a few of them. They have electronic driving circuitry that is often not well atmospherically shielded and/or isolated from line current, so they will make a bit of noise that radios will pick up. It is usually much more pronounced on the AM/BC band.
