International Lighting Seminar: Perspectives on Sustainability, Performance, Health & Smart Lighting

An international lighting seminar organised by the International Energy Agency’s (IEA) 4E Solid State Lighting Annex and the Swedish Energy Agency.

Digital lighting technology (Solid State Lighting, SSL) is now completely taking over the lighting market. The seminar gives you, as a supplier, consultant, researcher or otherwise involved in lighting issues, a unique opportunity to learn about the work of the SSL Annex’s international experts.  In the seminar, SSL Annex’s experts provide an insight into a number of current issues:

  • What is happening in ecodesign?
  • How did international co-operation on market data accelerate the phase out of fluorescent lamps in Europe?
  • Resource efficiency, product longevity and reparability – the next big challenge?
  • Ecodesign for Sustainable Products Regulation
  • How declared performance differs from test results – and what we can do about it
  • A test method cheaper, more realistic and easier evaluation of durability (now used in the Ecodesign Regulation)
  • SSL Annex’s recommended requirements for lighting products – and how they can be used
  • International comparisons of laboratories’ testing capacity – the third global test begins
  • Smart lighting – and energy smart lighting
  • New ways to describe colour and colour rendering – what could be the standard of the future?
  • Reducing light modulation for health and well-being – not just a matter of vision

The SSL-Annex is managed by six countries (Australia, Denmark, France, South Korea, Sweden and the UK) within the framework of the IEA’s 4E (Energy Efficient End-use Equipment) technology co-operation, in which some 15 countries participate.

In cooperation with test labs and international stakeholders, SSL-Annex experts evaluate test methods and test capacity of labs, compare claims with test data, develop general and harmonised requirements for lighting products that can be used by individual countries and international organisations. In addition, new technology applications such as smart lighting technology, LiFi, etc. are monitored and analysed. Light and health is an important aspect of the cooperation as energy efficient lighting should never have negative health effects.

Moderator: Prof Georges Zissis, Chair of the SSL Annex, La Place University Toulouse


13h00  Welcome and IEA 4E SSL Annex Overview

Nils Borg, Operating Agent, Borg & Co, Sweden  (link to video recording)

  • A link between policy standards, testing and requirements
  • Overview of work and activities


13h15  Challenges facing policy makers, what is happening in the EU?

Peter Bennich, Senior Advisor, Energimyndigheten, Sweden  (link to slides  –  link to video recording)

  • Why international cooperation matters to governments – what governments can add to the work of lighting industry and international professional organisations
  • Ecodesign lighting regulation review in 2023/24 – what’s around the corner?
  • Bye-bye fluorescent! – the RoHS Directive acts in Feb/Aug 2023 to protect public health


13h45           The new European landscape for product regulation: efforts to address product lifetimes, repairability, and resource efficiency

Prof Carl Dalhammar, International Institute for Industrial Environmental Economics, Lund University, Sweden (link to slides – link to video recording)

  • Energy efficiency is not enough
  • Resource efficiency, product lifetimes and repairability are our next big challenges
  • The EU legal proposal for the Ecodesign for Sustainable Products Regulation


14h15  Product Performance Claims and The Science of Verification

Steve Coyne, Light Naturally, Australia (link to slides – link to video recording)

  • The gap between nominal performance and test data – making the case for verification testing
  • SSL Annex’s quality and performance recommendation specs that are based on real performance data
  • Building confidence and proficiency in test laboratories a brief overview of the SSL Annex’s work comparing testing labs and how various parameters can be measured and evaluated
  • SSL Annex’s study of reducing the testing time for verifying product lifetime claims

14h45  Coffee break

15h15  Advanced smart lighting must also be energy smart

Casper Kofod, Director, Energy Piano, Denmark (link to slides – link to video recording)

  • SSL Annex Second Report on Smart Lighting – findings
  • Market measurement results and trends, including IEC/CIE standards
  • Expected developments in the future – integrating with controls


15h45  New colour metrics to consider in the Ecodesign Regulation Revision

Dr Yoshi Ohno, NIST Fellow, National Institute of Standards and Technology, USA (link to slides – link to video recording}

  • Ecodesign lighting regulation is under review this year
  • Appropriate colour metrics for LED light sources are important to consider
  • Review and pros/cons discussion of existing metrics – CRI, CIE Rf, IES TM-30, others….
  • Ideas for a potential way forward


16h15  Reducing temporal light modulation to protect health and well-being: More than just visibility

Dr Jennifer Veitch, National Research Council of Canada (link to slides – link to video recording)

  • Ecodesign regulations are based on predictors of two visual perceptions
  • Recent evidence shows that TLM affects brain activity & other behaviours
  • New metrics may need to be developed


16h45  Thanks and closing remarks (plus flicker measurement demonstration)
