I just read this article on LED lights and how they affect radio reception. Article by Ray Magliozzi (Car Talk brother) in our local paper. Trust you can enlarge it or download to read better.
No change in reception in our house. I have changed about 75% of the incandescents and florescents to LEDs. There may be some "interference" if measured with very precise instruments, but as a practical matter - I don't see it. Also I know that the FCC takes a very dim view of items that cause RF interference.
