The CFL bulb would not produce any more RFI than regular fluorescent lights would. There are so many fluorescent lights out there based on this video we should all be dieing from RFI emissions. We are bombarded from so much RFI emissions every day from our Radios,TV, microwave, cell phone and the list goes on and on. I think they are just trying to sell LED lights which is the next big push to save energy or they want to sell you RFI filters for your power. I would not let this video deter me from buying CFL.
