Hi Frank, I suspect that the 60 hertz radio buzz is caused by the breaking of the instantaneous current through the vapor at phase reversals. This sharp waveform would be loaded with high frequency energy. I know for sure that HID bulbs have to be reignited on each current cycle reversal whe

RE: [Vo]:Why do florescent lights make the radio buzz?

Just a guess, There is a general "arcing" characteristic of Fluorescent ballasts. The wide frequency range emissions created by these arcs act much like lightning to an AM radio signal. As the spectrum is wide enough, but varying amplitude, any amplitude modulated signal would be likely ef
