We are the Seattle-based/Puget Sound area section of the Illuminating Engineering Society,
a not-for-profit organization dedicated to all aspects of
the ART and SCIENCE of ILLUMINATION.

Every year, your support makes it possible for us to offer continuing education, award scholarships,
and create events that bring the Pacific Northwest lighting community together.

The IES is the recognized technical authority on illumination. For over a century its objective has been to
communicate information on all aspects of good lighting practice to its members, to the lighting community, and to
consumers through a variety of programs, publications and services. The strength of the IES is its diversified
membership consisting of engineers, architects, designers, educators, students, contractors, distributors, utility
personnel, manufacturers, and scientists — all contributing to the mission of advancing knowledge and disseminating
information for the improvement of the lighted environment to the benefit of society.

The IES is a forum for the exchange of ideas and information and a vehicle for its members’ professional development
and recognition. Through its committees, with hundreds of qualified members from the lighting and user communities,
the IES correlates research, investigations, and discussions to guide lighting experts and laypersons via
consensus-based lighting recommendations.
