The International Commission on Illumination (CIE: Commission Internationale de l’Eclairage) is a unique world-wide organization in matters of all phases of illuminating engineering, radiometry, photometry and colorimetry.

Recognized by the International Organization for Standardization (ISO) and International Electrotechnical Commission (IEC) as an international standardizing body of fundamental aspects of metrology evaluation and application of light and color, including other radiation aspects in the optical wavelength range.

CIE is devoted to international cooperation on all matters relating to the science and art of lighting, color perception, and digital color encoding.  The cooperation is based on monetary support from National Committees of participating countries, in exchange for participation in CIE committees and discount on CIE publications.

The United States National Committee (CIE-USNC) is a non-profit organization, run by volunteers, and supported by individual and organizational memberships.
