Society information

Leukos is an official publication of the Illuminating Engineering Society.

What is the Illuminating Engineering Society (IES)?

Founded in 1906, the mission of the IES is to improve the lighted environment by bringing together those with lighting knowledge and by translating that knowledge into actions that benefit the public.

The IES provides a wide breadth of publications, courses, standards, research, and networking opportunities to approximately 8,000 members around the world from all disciplines within, and ancillary to, the lighting industry. We are over 1,000 volunteers strong within nearly 100 committees that create technical content, support education, and grow and serve our membership and strategic partners through programs and events. Members have the ability to learn from, and build, peer networks on a local basis within our 97 sections located throughout the United States, Mexico, and Canada.

Our vision for the future is to build upon a century of excellence to create the premier lighting community dedicated to promoting the art and science of quality lighting to its members, allied professional organizations, and the public.

Cause: Improving life through quality of light

WE BELIEVE

Light is vital to life; it is as important as air, food, water and shelter

Light and the absence of light affect human vision, health, and behavior

Lighting should enhance comfort and aesthetics, important components of the built environment

Lighting designs should respond to human needs, while minimizing negative environmental impacts

Lighting quality should be a priority at the onset of any design and be maintained throughout the construction process

Sustained research is necessary to quantify lighting benefits that improve the quality of life

Lighting Standards and policies should be based on the consensus of topic experts informed by scientifically validated data

As the lighting authority, the IES believes that collaboration with other non-lighting organizations on lighting policies and regulations is essential for the benefit of the public interest

Global collaboration and member participation are vital to the long-term viability of the lighting community

Education is critical to maintaining a robust, dynamic lighting community and for continued professional growth
