Solid State Lighting Annex

New lighting technologies including more efficient sources and smart lighting systems and controls offer the potential to reduce global electricity use for lighting by 50%.  The SSL Annex is actively working to develop information and analysis to support governments working to transform their lighting markets, improving both the energy efficiency and quality of our illuminated spaces.  

4E’s Solid State Lighting Annex brings together top researchers and experts from around the world to jointly address challenges in the rapidly evolving lighting market. The activities undertaken by the SSL Annex are complementary and supportive of the work of governments, international standardisation bodies, and the research & development being conducted by industry and academia. Through this work, the SSL Annex is working to accelerate the global transition to solid state lighting.
