Why need Flicker test?

Flicker is the constant fluctuation of light output from on to off, almost all AC-powered traditional light sources exhibit some degree of periodic modulation or flicker, the consequences of flicker can result in headaches, migraines, siezures, dizziness and unexpected bad quality of your photography or video.
