   This effect is eliminated by paired lamps operating on a lead-lag ballast. Unlike a true strobe lamp, the light level drops in appreciable time and so substantial "blurring" of the moving part would be evident. Fluorescent lamps may produce flicker at the power supply frequency (50 or 60 Hz), which is noticeable by more people.

6. Gas-discharge lamp - Wikipedia

   en.wikipedia.org/wiki/Gas-discharge_lamp

   A flicker light bulb, flicker flame light bulb or flicker glow lamp is a gas-discharge lamp which produces light by ionizing a gas, usually neon mixed with helium and a small amount of nitrogen gas, by an electric current passing through two flame shaped electrode screens coated with partially decomposed barium azide. The ionized gas moves ...
