the perception of light flicker by handling complex loads from multiple sources or with varying rates of occurrence. WHAT IS FLICKER? Flicker is a very complex aspect of power quality that is somewhat subjective by nature due to how an individual perceives it. When most people or power consumers refer to flicker, it is usually in reference
Flicker, or more precisely temporal light modulation (TLM), has re-emer-ged as a problem with the introduction of LED-based lighting techno-logy. TLM, meaning variations in light intensity over time, may have negative effects on human health, causing annoyance, headaches, eyestrain and migraine. In addition to the unnecessary suffering TLM
Unofficial definition: “Anything unpleasant that is related to variations in luminance over time” It could refer to: + True light source flicker. + Stroboscopic effects (indirectly perceived flicker)

IESNA has defined two metrics for flicker: Percent flicker. 0-100% scale. Older, but more well-known and more commonly used. Accounts for average, peak-to-peak amplitude. Does not account for shape, duty. cycle, frequency. Flicker index. 0-1.0 scale.
Jan 1, 2007 · Let's examine voltage fluctuations as a cause of flicker, what prompts fluctuations, methods of their mitigation, and applicable standards regarding flicker levels.

Oct 12, 2024 · The flickering effect of light generated in modern lamps can occur under stable voltage conditions in the supply network. The main subjects of the conducted research were solid-state light sources—light-emitting diode (LED) lamps, currently available on the lighting market.
