On 8 May, the Swedish Energy Agency and the International Energy Agency’s (IEA) 4E Smart Sustainability in Lighting and Controls (SSLC) Platform held an International Lighting Seminar to discuss the research, data and findings that help address key issues in the lighting market.

Lighting stakeholders, suppliers, designers, consultants, researchers and other experts participated and heard first-hand about the work of the IEA 4E SSLC Platform’s Experts covering:

• Smart lighting – what are the latest developments and trends? Are there opportunities for energy savings that will not inhibit innovation? Is there evidence for additional energy savings beyond standby power reduction.
• Colour metrics – Will CRI (used in many regulations) be replaced by Colour Fidelity Index? What discussions are in progress in the international standardisation community at this time?
• Market trends – looking back over the last ten years, how has the LED lighting market evolved in terms of flicker (temporal light modulation metrics) and efficacy? And the importance of access to government laboratories in providing test data to support/validate registration data.
• Lighting metrology – what were the findings from the recent Interlaboratory Comparison 2023? What did those findings help to trigger / change in the lighting community?
• Lighting and health – how are we affected by flickering light sources? What are safe thresholds that could be adopted?  What is the TWINKLE project?
• Policy making – what is happening with the ecodesign regulation? The review clauses and the work that still needs to be done that will support the regulation and SSLC contributions to date.
