Using electronic ballasts, the current frequency is boosted up to 60 kHz in some models. Does the fluorescent lamp continue to flicker at that frequency or does it produce continuous light?
In this wikipedia page it is mentioned that:
Fluorescent lamps using high-frequency electronic ballasts do not produce visible light flicker, since above about 5 kHz, the excited electron state half-life is longer than a half cycle and light production becomes continuous.
But no citation to confirm this fact. Can anybody confirm/deny this with an explanation of that electron state half-life in that case?
