1 Scope This document describes an objective stroboscopic effect visibility (SVM) meter, which can be applied for performance testing of lighting equipment under different operational conditions. The stroboscopic effects considered in this document are limited to the objective assessment by a human observer of visible stroboscopic effects of temporal light modulation of lighting equipment in general indoor applications, with typical indoor light levels (> 100 lx) and with moderate movements of an observer or nearby handled object (< 4 m/s). Details on restriction of the applicability of the stroboscopic effect visibility measure is given in Clause A.1. For assessing unwanted stroboscopic effects in other applications, such as the misperception of rapidly rotating or moving machinery in an industrial environment for example, other metrics and methods can be required. The object of this document is to establish a common and objective reference for evaluating the performance of lighting equipment in terms of stroboscopic effect . Temporal changes in the colour of the light (chromatic effects) are not considered in this test. This document describes the methodology for SVM and does not define any limits. The objective method and procedure described in this document are based on CIETN 006:2016 on temporal light artefacts ( TLAs ). The method described in this document can be applied to objectively assess the stroboscopic effect ...
