The Evaluation of Flicker in LED Luminaires

Flicker is the periodic change in the instantaneous light output of a light source.

In most conventional light sources driven by line current, the frequency of the flicker is two times the frequency of the line current.

The increased use of high frequency electronic ballasts has greatly decreased the amount of flicker present in the indoor environment.
