UNEP will hold a webinar on 7 May at 09h00 Stockholm time with Mr. Tony Bergen, Secretary of CIE Division 2. Mr. Bergen will provide

“Smart” lamps combine technology breakthroughs in wireless communications and light emitting diodes (LEDs). Often controlled by a smartphone app, these lamps can dim, change colour

Today, the IEA 4E SSL Annex has published a new website that reflects its new five-year programme of research and cooperation. The new and completely

The IEA 4E SSL Annex congratulates Professors Isamu Akasaki, Hiroshi Amano and Shuji Nakamura for their joint award of the 2014 Nobel Prize in Physics, awarded for developing blue-light LEDs that enables general illumination white-light LED products.

Starting in 2011, the SSL Annex launched a study to review all of the major health-related literature associated with LED lighting. In 2014, the SSL Annex published a comprehensive review of this literature summarising the human health impacts of SSL.

Today, the IEA 4E SSL Annex, supported by ten national governments, announced the publication of a comprehensive review of all the current life-cycle assessment studies on Light

Today, the governments of ten countries announced the publication of the world’s largest interlaboratory comparison on solid state lighting (SSL). This project compares the ability of 110 laboratories worldwide to test Light Emitting Diode (LED) lamps and luminaires. The outcome of this large-scale interlaboratory comparison will help governments and manufacturers around the world ensure that new LED products sold to consumers and companies are of high quality and meet the claimed performance.
