This Technical Report adopts IEC TR 63158:2018 which describes an objective stroboscopic effect visibility (SVM) meter, which can be applied for performance testing of lighting equipment under different operational conditions.

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
CIE TN 006:2016 on temporal light artefacts (TLAs).
The method described in this document can be applied to objectively assess the stroboscopic
effect of lighting equipment that is powered from any type of source, AC mains, DC mains,
battery fed or fed through an external dimmer.
