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.
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
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
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
RF-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.
Members of the CNC/CIE are reminded that they are able to get a discount on all CIE publications.
