SSL FAS 21 Flicker Analyzing System

Light flicker requirements by ECODESIGN become valid in September 1st, 2021


SSL FAS 21 flicker analyzing system consists of SSL photometer, SSL flicker sw, a specially modified power supply capable of luminaire input voltage modulation and a SSL stand&stray light tube assembly for minimizing the disturbance of the background light (e.g. roomlight). It is a cost effective solution for determining the flicker parameters demanded by the  ECODESIGN regulation and CIE TN 006:2016. Flicker properties of the tested luminaire are classified according to IEEE 1789 - 2015.

Features / Advantages 

  • dedicated and cost effective setup for flicker analysis of luminaires
