National Committees

The CIE has several types of membership. At the highest level are the National Committees. The affairs of the CIE are vested in National Committees which have the responsibility for decisions on all matters relating to the organization. The composition of the National Committees varies from country to country, but each is required to represent and have in its country the cooperation of all organizations having an interest in light and lighting. So each country can have only one National Committee.

A country seeking to join the Commission shall form, with the co-operation of organizations within that country having a special interest in light and lighting, one National Committee. This National Committee must submit evidence that it meets all necessary requirements, and shall send its application to the Central Bureau. Approval of the application is decided by the National Committees.

Associate National Committees

Countries that have established a new National Committee, or developing countries which have a National Committee already, may join the CIE on an intitial as an Associate National Committee. Associate National Committee Membership isfor a four year period, after which time it is expected that an application shall be made for establishing a  full National Committee.
