Solid State Lighting Annex

Solid State Lighting (SSL) provide high-quality, energy-efficient lighting that surpasses traditional technologies at a lower life-cycle cost. However, there is a wide variation in the performance and quality of SSL products currently found on the market, and some of the poor-quality products could undermine consumer confidence in SSL, delaying market adoption and the associated energy and environmental benefits.

Launched in July 2010, the IEA 4E SSL Annex is a joint initiative of seven countries working together to address challenges with SSL technologies. The SSL Annex member countries recognise there are significant advantages in engaging in an international collaboration and joint activities relating to SSL performance and quality. Sponsoring governments of the SSL Annex include Australia, Canada, Denmark, France, Korea, Sweden and the United Kingdom.

Publication of Final Report: Visual Perception under Energy-Efficient Light Sources – Detection of the Stroboscopic Effect under Low Levels of SVM

The SSL Annex is pleased to publish today the Final Report for a research project that examined visual perception associated with temporal light modulation, and more specifically the stroboscopic effect. An interim draft report on this study was published in December 2018, and it has since been extended in sample size and in the scope of analysis and has undergone peer review.

About SSL

With a focus on product performance, harmonized testing, and health and environment factors, the goal of the SSL Annex is to assist governments in their support of quality SSL products that will save consumers money and reduce carbon emissions.
