IEC TR 63158:2018

Equipment for general lighting purposes - Objective test method for stroboscopic effects of lighting equipment

IEC TR 63158:2018(E) 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 ( The contents of the corrigendum of July 2018 have been included in this copy.
