LED lighting continues to expand its market share, taking over conventional technologies in all end-use applications, yet challenges and opportunities relating to lighting remain. This International Lighting Seminar brings together Experts from the IEA 4E SSLC Platform to present their latest work on a range of topics including a new Interlaboratory Comparison on Temporal Light Modulation (commonly known as flicker); research into new test methods and metrics; a literature review of health effects associated with lighting; the opportunity and impact on energy consumption of smart lighting; and a recent life-cycle assessment comparing linear fluorescent lamps and LED tubes. The SSLC Platform is offering this free half-day seminar – both on-line and in-person at the University College London campus – to anyone interested. Please register here.
Moderators: Prof Georges Zissis, Chair, IEA 4E SSLC Platform, La Place University Toulouse
Nils Borg, Manager, IEA 4E SSLC Platform, Stockholm, Sweden
Note: There will be a short Q&A after each presentation.
