PHOTOMETRIC FLICKER CHARACTERIZATION STUDY ON ENERGY SAVING LAMPS UNDER WIDE VARIATION VOLTAGE AC NETWORK

With the advent of Solid-State Lighting came a renewed interest in the study of flicker. Potential effects include brightness enhancement, but also discomfort, ocular fatigue, phantom and stroboscopic effects. Both IEEE and IEC developed new metrics, but at the time of writing no firm consensus h...
