The FCC should get their own shit together before attacking innocent third parties. This is now happening in a lot of countries, we have been told by our governments to install the new lights, manufacturers have got them approved for radio interference, and then the shit hits the fan when the governments sell off the frequencies for use in a more demanding and sensitive manner than before.
According to a 2012 GE bulletin, the lighting ballasts were tested in accordance with FCC requirements, but a small number produced high-frequency radio emissions “that have the potential to cause interference with certain types of wireless communications.” The bulletin also said GE would replace affected equipment.
In this case, it seems that there was a manufacturing defect. FTFA:
I'd be putting the blame on the manufacturer (and to a lesser extent the installing contractor) in this case, not the FCC.
