Not sure if this should be in the lighting section but I am a noob so here goes.

I was reading something about electric ballasts producing emf or rf interference that could fuck with things like radio and digital cable reception. One guy wrote a review about his lumatek ballasts saying they messed up his neighbors digital cable reception and they traced it back to his place. I have a couple lumatek ballasts and i live in a townhouse so I'm wondering if that really happens or if that guy was just bullshitting.

Anyone using these ballasts that can tell me whats up?
