Equipment for general lighting purposes. EMC immunity requirements - Objective light flickermeter and voltage fluctuation immunity test method1 Scope This part of IEC 61547 describes an objective light flickermeter, which can be applied for the following purposes: measuring the intrinsic performance of all lighting equipment without the application of voltage fluctuations in terms of illuminanceflicker; during this measurement, the lighting equipment is supplied with a stable mains; testing the immunity performance of lighting equipment against (unintentional) voltage fluctuation
