Today, the Smart Sustainability in Lighting and Controls (SSLC) Platform published a comprehensive review of the scientific knowledge acquired over the last ten years on the effects of solid state lighting (SSL) on human health.
On 14th May, the SSLC Platform organised an international lighting seminar at Senate House, University of College London. The slides and video recordings from this seminar are now available on our website.
An in-person (London, UK) seminar and on-line webinar.
The SSL Annex has been given the “Global SSL Award for Outstanding Achievement” from the International Solid State Lighting Alliance on 27 November in Xiamen, China. This award recognises the thirteen years of research, reports and other information that the SSL Annex has shared with the global lighting community.
Preliminary findings from the IEA 4E SSL Annex show that environmental impact for T5 lamps can be reduced by 44% and for T8 lamps by 61% if they are replaced by LED retrofit tubes. These are LED “plug-and-play” retrofit tubes that can be installed directly into existing fluorescent fixtures.
On 9 October 2023, the SSL Annex held a webinar on new features in smart lighting that impact energy consumption delivered by Casper Kofod, an Expert based in Copenhagen, Denmark. The webinar summarised the findings from a report on Smart Lighting published last year.
The SSL Annex has launched its 2023 Interlaboratory Comparison (IC 2023) of temporal light modulation (TLM) measurements. IC 2023 is open to all photometric labs that have capability for measuring TLM quantities, in particular, short-term flicker indicator (PstLM), and stroboscopic effect visibility measure (SVM), of LED lighting products.
On 27 March 2023, the IEA 4E SSL Annex organised an international lighting seminar in cooperation with the Swedish Energy Agency. This seminar was held
Today, the IEA 4E Solid State Lighting Annex is publishing a major report on Smart Lighting. This report focuses on the smart lighting features that
Today, the IEA 4E SSL Annex published its new and updated “quality and performance requirements” for the most popular LED lamps and luminaires. These specifications, elaborated
20 December 2021, Stockholm. The IEA 4E Solid State Lighting Annex (SSL Annex) today published the final report from its 2017 Interlaboratory comparison. With 36 participating laboratories
A new report by the IEA 4E Solid State Lighting Annex provides a look across the body of literature on lifetime definitions for LEDs and
The IEA-4E SSL Annex is updating the voluntary quality and performance requirements which address product attributes such as colour, lifetime, power, and efficacy for common
The SSL Annex is pleased to publish today the Final Report for a research project that examined visual perception associated with temporal light modulation, and more specifically the stroboscopic effect. An interim draft report on this study was published in December 2018, and it has since been extended in sample size and in the scope of analysis and has undergone peer review.
The European Commission published the new ecodesign and energy labelling regulations that apply to all lighting products in Europe. Called the “One Lighting Regulation”, the scope of coverage applies to all light sources – incandescent, halogen, fluorescent, high intensity discharge and solid-state lighting sources. The regulations set out mandatory quality and performance requirements as well as labelling, informational and product registry database requirements.
The IEA 4E SSL Annex and the Danish Technical University (DTU) worked together to plan a one-day seminar covering recent research on health and testing, including topics such as temporal light modulation and lifetime. The seminar also covered the new EU energy label for lighting and the product registry database.
As part of the work of the Interlaboratory Comparison 2017 (IC 2017), the SSL Annex has today published the Nucleus Laboratory Comparison Report. This report presents the results of a comparison between the Korea Institute of Lighting and ICT (KILT), Korea, and Laboratoire national de métrologie et d’essais (LNE), France. This work was conducted to verify their measurement uncertainties and to bring equivalence of their measurements of the IC 2017 artefacts. Based on the results of this comparison, the correction factors for equivalence of measurements by the two Nucleus Laboratories as prescribed in IC 2017 Technical Protocol were determined.
An international seminar on certification, standards and requirements was held on 4 April 2019 at Le Meridien Hotel in Seoul, Korea. The Korean Institute of Lighting and ICT (KILT) and the SSL Annex worked together to organise this seminar which included leading experts from both the SSL Annex and regional governments.
The CIE is holding a Tutorial and Practical Workshop on CIE S 025, the first international measurement standard for LED lamps, luminaires and modules. This workshop will be held at the Russian Lighting Research Institute (VNISI) in Moscow on 5 – 7 November.
The SSL Annex held a one day conference in Sydney with presentations by the SSL Annex’s Experts on a range of topics related to LED lighting, efficiency and quality. The conference gathered over 50 Australian lighting experts from industry, research and government.
