Once again I'm amazed by the amount of electromagnetice noise that come out of my LED units. While out one night I layed my Photon Fusion headlight next to my radio on the AM band. There's was some heavy emmision coming off of it hitting the 700~900Khz area.
Evening my Fenix L2P will sqeeal for a few seconds during turn on. I guess this is the down side to the regulation and high frequency switching going on? It's worth it!
