CIE 2019 Washington DC  

CIE 2019, the 29th Session of the CIE, Washington DC, June 14 - 22, 2019

The Session is an important event, which will bring together the international membership of the CIE, as well as other experts and stakeholders in the fields of light and lighting.

It is our great pleasure to invite you to join us for the activities at the 29th Quadrennial Session of the International Commission on Illumination (CIE), hosted by the United States National Committee of the CIE. The Session, which will be held from June 14 to 22, 2019, in Washington DC, is an important event, which will bring together the international membership of the CIE, as well as other experts and stakeholders in the fields of light and lighting, that is vision and colour, measurement, lighting applications, photobiology and image technology.  It offers an opportunity to meet colleagues from around the world, to share knowledge both theoretical and practical, and to contribute to the work of CIE Technical Committees.

This Quadrennial Session involves a combination of three distinct aspects of the CIE:

Administrative meetings held from June 14 to June 16, which mark a turning point, at which the CIE Board of Administration brings on new members, and at which representatives from each CIE member country meet at the General Assembly to set the course of the organization for the next four years.  There will also be ample social time to connect with colleagues and friends both old and new.

A three-day conference held from June 17 to June 19, for the exchange of technical knowledge and results of new research, through papers, presentations and posters.

Three days of Technical Committee meetings held from June 20 to June 22, in which experts from each of the CIE Divisions work on the development of CIE International Standards and Technical Reports;

While vitally important for CIE members, this is also a precious opportunity for anyone with an interest in light and lighting, from whatever branch of art or science, from academia or industry, to come together and discuss their interests with like-minded people from around the globe.

We hope that you will join us in Washington DC at the Wardman Park Marriott to celebrate the 29th Quadrennial Session of the CIE.

For further information and detailed arrangements, please visit the Conference Website, either directly at, through the CIE homepage at, or the US national committee website at

We look forward to welcoming you at the CIE Session in Washington DC in June 2019.
