In October 2024, the IEA 4E SSLC Platform published a report that represents a synthesis of health and lighting studies published over the last decade. The effects of lighting on health are technology agnostic, however advances in physiology and medicine have contributed to new awareness and understanding of the impacts of light on human health. This study examines some features of SSL products that may pose a risk and which could be improved or applied differently to achieve better outcomes in terms of health and well-being. The report covers both acute effects (effects that develop during or immediately following an exposure) of optical radiation on the eye and the skin, discomfort glare, circadian disruptions, neuro-behavioural effects, and temporal light modulation (TLM), as well as long-term effects (effects that build over months or years) including age-related macular degeneration, myopia and cancer risk.

In order to communicate the broad set of findings from this report, the SSLC Platform convened a series of webinars. The findings were divided up into three one-hour webinars which were each presented twice, once for Australian/Asian time zones and once for American/European time zones. These webinars were recorded and can be viewed by clicking on the embedded videos below. PDF copies of the slides presented during each webinar are also available for download below.
