Methods for measuring the new PstLM flicker index according to the ecodesign requirements for LED lighting
The revised regulation of the European Commission on ecodesign for light sources introduces new requirements for light flicker indicators, including PstLM, which determines the resistance of the light source power supply system to network disturbances. PstLM stands for Short Term Perceptibility for light modulation. The new requirements enter into force in September 2021 and will [...]
