The Alliance for Solid-State Illumination Systems and Technologies (ASSIST), a program of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, has released a publication that proposes a new method of evaluating human perception of directly observed light source flicker. The publication, ASSIST recommends…Recommended Metric for Assessing the Direct Perception of Light Source Flicker, provides specific measurement procedures and calculations to objectively determine whether the amount of flicker from a light source is above or below the threshold of human perception. The metric is applicable to any waveform shape and frequency and is based on peer-reviewed laboratory and human factors experiments.

The Alliance for Solid-State Illumination Systems and Technologies (ASSIST), a program of the Lighting Research Center (LRC) at Rensselaer Polytechnic Institute, was established by LRC in 2002. As the collaboration between researchers, manufacturers, and government organizations, ASSIST’s mission is to conduct collaborative research to enable the broad adoption of LEDs. ASSIST is sponsored by many LED manufacturers including Acuity Brands Lighting; Amerlux; Cooper Industries; Cree; Dow Corning; GE Lighting Solutions etc. ASS...
