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 our 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.

29th Quadrennial Session of the CIE

The 29th Quadrennial Session of the CIE, hosted by the United States National Committee, is being held June 14 to 22, 2019, in Washington D.C. Anyone with an interest in light and lighting is encouraged to take this opportunity to discuss their interests with like-minded people from around the globe. Further information on the meeting can be found at


12th Biennial Joint Meeting of the CNC/CIE and CIE-USNC and CORM 2019 Annual Technical Conference

The next meeting of the CNC/CIE will be a joint meeting with the Council for Optical Radiation Measurements (CORM) and CIE-USNC. It will be held in Ottawa the week of October 28th and will include a three day technical session and laboratory tours as well as the business meetings for the three organizations. Everyone is encourage to participate in what promises to be an interesting and informative Conference. Further details are now available in the attached Call for Papers. We look forward to hearing about your latest research on any aspect of light and lighting of interest to the CORM and/or the CIE community.

Request for Information

The following request for information has been issued by the CIE Central Bureau. Canadian Information on this topic would be welcome.

CIE JTC 12: The CIE Joint Technical Committee JTC 12 (D1/D2/D8) “The measurement of sparkle and graininess” is discussing the definition of measurement scales of sparkle and graininess. For this purpose, it is collecting visual data, which can be used for scaling or for devising texture difference formulae. Please, if you have obtained or you are planning to obtain visual data of sparkle and graininess and are willing to share them, or if you want to collaborate in the development of the measurement scales of sparkle and graininess, contact the JTC 12 Chair, This email address is being protected from spambots.
