The paper is focused on design, realization, verification and utilization of a light-flickermeter simulating response of an average observer on disturbing light flicker under specific conditions. The design of the light-flickermeter is based on standard IEC flickermeter measuring scheme where the measuring chain does not include model of the reference incandescent bulb and where irradiance (radiant flux) waveform produced by any lamp is measured and analyzed. It means that this type of flickermeter output is expected to be independent on a light source type producing light flicker. The developed instrument evaluates measured luminous flux fluctuation utilizing appropriate hardware and signal processing by means of virtual instrumentation in LabView. Results of the flickermeter verification then advanced performance analysis and utilization for measurement of various lamps sensitivity or immunity to different kind of voltage disturbances are shown and discussed.
