Worldwide comparison of 110 LED testing laboratories: Results Presented
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.

The IEA 4E SSL Annex issues new report promoting CIE’s new global test standard
The IEA 4E Solid State Lighting Annex today published a new report promoting CIE’s new global test standard. The report, entitled “Application Study of CIE S 025/E:2015”, evaluates the new international standard for use by key stakeholders as the basis for measuring important quality and performance aspects of LED lighting products. The SSL Annex has concluded that the new CIE standard is suitable for its upcoming global interlaboratory comparison of goniophotometers.
The “How To” Briefing Accompanying the Global Lighting Challenge
Following the launch of the Global Lighting Challenge aiming at deploying 10 billion super-efficient light sources, the IEA 4E SSL Annex today published an Executive Briefing that summarises the best practices, programmes and other initiatives undertaken by its member countries to accelerate the adoption of quality, energy-efficient LED technology in their markets.
