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. Some quick facts on the CNC/CiE are available here. For more detailed information, go to About the CNC. For a list of recent events see our Past 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.

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 most recent addition is a database on skin colour. It accompanies the recent Technical Report on Measurement of Human Skin Colour.
The datasets are easily findable on the CIE website along with references to the internationally approved CIE publications where they were originally published.
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 Technical Committees. In addition to TCs, the CIE has set up several 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.
To find out more information about ongoing CIE technical work, contact the Canadian Division member in your area of expertise. Information on the newest TCs anf RFs can also be found in the latest CIE Newsletter.
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.
Members of the CNC/CIE are reminded that they are able to get a discount on all CIE publications. The latest discount code, effective February 2025, is currently available in the members only area under Publication Discount Code. To log in, go to CNC/CIE Members.
