Solid State Lighting (SSL) has the potential to provide high-quality, energy-efficient lighting that surpasses traditional technologies and offers 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 penetration and the associated energy and environmental benefits.
Launched in July 2010, the IEA 4E SSL Annex is a joint initiative of nine countries working together to address common challenges with SSL technologies. The Annex member countries understand 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, the Republic of Korea, Sweden, the United Kingdom and the United States.
