Confidence Intervals for Luminous Flicker Measurements: Comparison of Various Approaches

This paper aims to assess the effect of measurement noise on the evaluation of the flicker metrics defined in IEEE Standard 1789-2015. To this end we compare two analytical approaches and Monte Carlo simulations w.r.t. their ability to cope with natural bias of FP and to estimate measurement uncertainty. Two similar datasets from laboratory experiment representing luminous fluctuations of fluorescent light are considered. Recommendations on how to safely evaluate Percentual Flicker and Flicker Index are given based on the hereby presented work.
