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. Member governments of the SSL Annex include Australia, Denmark, France, Korea, Sweden and the United Kingdom.
