LED Lighting Performance Analysis: Temporal Light Modulation, 2014-2025

“LED Lighting Performance Analysis: Temporal Light Modulation, 2014-2025”, by Dr. Carsten Dam-Hansen and Dr. Gillian Isoardi, discusses how Temporal Light Modulation (TLM) metrics (i.e., short-term flicker index (PstLM) and stroboscopic effect visibility measure (SVM)) for LED lighting products evolved between 2014 to 2025. The analysis examines supplier-reported product data from the European Product Registry for Energy Labelling (EPREL) database, including over 130,000 lighting products for PstLM and over 230,000 for SVM. The assessment also included laboratory measured product performance data for hundreds of LED lamps tested by the member governments of the SSLC Platform between 2017 and 2024.
