Interference to Air Traffic Control caused by incandescent light bulbs (2020)

I thought this was interesting due to the type of light bulb. LED and CFL lighting has been known to cause RF interference [1], but I wasn't aware that it was also possible with incandescent bulbs.

I wish they provided a little more technical details as to what mechanism was responsible for the noise.
