Résumé	Temporal Light Modulation (TLM) or “flicker” as it is colloquially known can have visual, neurobiological, performance, and cognitive effects on viewers. The International Electrotechnical Commission and the Commission Internationale de l’Eclairage have identified two metrics that may be used to characterize lighting systems’ TLM: PstLM, to predict visible flicker at frequencies below 80 Hz; and SVM, Stroboscopic Visibility Measure, for the higher frequency stroboscopic effect. While scientific development of these metrics and their associated measurement protocols continue, there is a parallel discussion taking place concerning the appropriate levels for these metrics in regulations. The SSL Annex commissioned a study from researchers at the National Research Council of Canada (NRC) and the Centre Scientifique et Technique du Bâtiment (CSTB) in France, to investigate detection rates for the stroboscopic effect in response to commercially-available light emitting diode (LED) light sources characterized using the SVM, and particularly to assess the population variability in this perception among people sensitive to visual stress. The final report on this work provides insight into both stroboscopic visibility and the acceptability of the conditions for the full sample of 85 people and for the more sensitive individuals. The report follows the publication of a peer-reviewed journal article in Lighting Research and Technology.
