Canadian National Committee of the CIE

Welcome to our website. The CNC/CIE is the collective Canadian voice of people interested in the science and art of light and lighting. Membership is open to anyone interested in any aspect of lighting including vision, photometry, colorimetry, photobiology and the application of these to the use of light and lighting both indoors and out. For further information on the CNC/CIE go to About the CNC. For a list of recent events see our Activities page.

As part of its mandate, the CNC/CIE supports the Standards Council of Canada by providing the core of the membership of the Canadian mirror committee to ISO/TC 274 – Light and Lighting. ISO/TC 274 is responsible for standardization in the field of application of lighting in specific cases complementary to the work items of the CIE and the coordination of drafts standards from the CIE. For further information on ISO/TC 274 see About ISO/TC 274 or visit the ISO website.

CIE-USNC Webinar: "Measuring Light for Vision, Health, and Everything Else”

The US CIE National Committee (CIE-USNC), in collaboration with the Illuminating Engineering Society (IES), will host a webinar on the history and use of V(λ) on 25 October, 2024, 10-11 AM EDT. The presentation will celebrate V(λ)’s history and show how we combine it with CIE metrology for ipRGC-influenced light effects. It will also touch on lighting recommendations, including ANSI/IES RP-46-23, which supports the physiological and behavioural effects of lighting in interior environments.

Speakers: Dr. Alan Lewis and Dr. Jennifer Veitch

This is a free event. Registration is available here.

Joint CORM & CIE-USNC Conference 2024

The Council for Optical Radiation Measurement (CORM) and the US CIE National Committee (CIE-USNC) are holding a virtual three day conference, 12-14 November, 2024. This event brings together professionals from the optical radiation industry, academia and National Metrology Institutes (NMI's) such as the National Institute of Standards and Technology (NIST), National Research Council (NRC) of Canada, and National Center for Metrology (CENAM) of Mexico. 

Papers for presentation at the conference are still beng accepted. The deadline for submissions  is 1 October, 2024. Details on submitting an abstract can be found on the CORM website.

Registration for the CORM/CIE-USNC 2024 Conference, along with the agenda, can be found here. The deadline for early registraion is 25 October 2024.

CIE Research Webinar "CIE Research Strategy 2023-2027"

 Dr. Jennifer Vetch, President of the CIE, will lead a webinar on the "CIE Research Strategy 2023-2027." This event will take place on October 10 at 3 PM CEST via Zoom.

This webinar is an excellent opportunity for researchers, research organizations, research funders and funding agencies to gain insights into the future direction of CIE's research initiatives. Dr. Veitch will provide an overview of the strategic priorities and key focus areas that will shape the research landscape over the next several years.

Please forward this invitation to your funding agencies and other interested parties to ensure they don't miss out on this important event.

Registration for this event is available HERE. Additional information will be available later this summer.

CIE Midterm Meeting 2025

The 2025 CIE Midterm Meeting will be held in Vienna, Austria. It features the Scientific Conference, CIE 2025, to be held from July 7-9, 2025. This three-day conference brings together the CIE community and its stakeholders to advance the science of light and lighting, as well as the technical and organizational work of the CIE. The scientific conference will be preceded by the CIE General Assembly and other administrative meetings from June 4-6, 2025, and followed by the CIE Division and Technical Committee (TC) meetings on July 10th and 11th, 2025.

The submission system for contributions is now open. Instructions for submitting a paper can be found here. The deadline for submitting an abstract is 10 December 2024.

Further details are available on the Conference website or by downloading the First Conference Announcement.

Explore CIE's Comprehensive Datasets and Metadata Resource - Now Available Online

Looking for CIE datasets, like the new CIE L41 LED reference spectrum or the more traditional standard Illuminant A? For you, the CIE has curated its key and most popular FAIR datasets.

The datasets are easily findable on the CIE website along with references to the internationally approved CIE publications where they were originally published.

New CIE Research Forum: Lighting in the Usage of Augmented, Virtual, and Mixed Reality Devices

CIE has a new Research Forum (RF-04) on Lighting in the usage of augmented, virtual, and mixed reality devices. It aims to research the lighting issues raised from potential applications and scenarios of Augmented Reality (AR) technology. These potential applications include but are not limited to map navigation, industrial workshop assembly drawings, and instructions, security alert and target identification, medical surgery application, etc. If you want to join in the discussion of RF-04 then simply complete the TC and RF Membership Application form (filling in the requirements for RF membership) and send it to This email address is being protected from spambots. You need JavaScript enabled to view it. for passing on to Molly Mou,the RF-04 Convener.

Call for Experts

CIE has over 70 Technical Committees (TCs) working on new reports and international standards. A brief description of each TC is available under CIE Technical Committees. If you have expertise to contribute to any of these, especially the new ones shown below, you can apply for membership by sending a completed CIE TC Membership form and CIE Copyright Agreement form  to the relevant TC Chair, with a copy to the This email address is being protected from spambots. You need JavaScript enabled to view it. and the CNC/CIE Secretariat. Please note that all Canadian members of TCs must be or become members of the CNC/CIE.

JTC 20 (D6/D2) Wearable alpha-opic dosimetry and light logging methods, limitations, device calibration and data schemes

In addition to Technical Committee, you are encouraged to participate in CIE Research Fora (RFs). RFs exist to facilitate ongoing knowledge exchange and research on a scientific topic or research area where there is insufficient completed scientific work to support the work of a CIE Technical Committee. 

Currently the CIE has four RFs:

RF-01: Spectral Imaging
RF-02: Matters relating to temporal light modulation
RF-03: Matters related to Colour Rendition
R
F-04: Lighting in the usage of augmented, virtual, and mixed reality devices

CIE Publications

One key activity of the CIE is the publication of technical and scientific work in the form of Technical Reports, International Standards, and Technical Notes. Technical Notes are freely available. Technical Reports and International Standards can be purchased through the CIE Web Shop. Summaries of recent publications, including links to recent Technical Notes, can be found under New Publications.

In addition to formal publications, the CIE Board of Administration will, from time to time, issue Position Statements. Summaries of recent CIE Position Statements can be found here.
