Launch of IEA 4E SSL Annex 2017 Interlaboratory Comparison of Goniophotometer Measurements (IC 2017)

The IEA 4E Solid State Lighting Annex today is formally announcing a global interlaboratory comparison for goniophotometers (in short IC 2017). With 70 labs from around the world pre-registered, IC 2017 has the potential to be the largest single interlaboratory comparison of goniophotometers. The programme is designed in compliance with ISO/IEC 17043 to serve as a proficiency test for SSL testing accreditation programmes that recognise this comparison and it is based on the new CIE S 025/E:2015 test method for LED equipment.

New LED performance recommendations help promote global harmonisation of product quality and performance

The IEA 4E SSL Annex published seven new and updated “quality and performance tiers” for popular LED lamps and luminaires. These seven documents offer policy makers and programme administrators guidance on which parameters to consider and the levels that may be appropriate when specifying or regulating LED products. Parameters include efficacy, lifetime, light colour, durability, and many other metrics.

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.
