Established in 1906, the Illuminating Engineering Society is the recognized technical and educational authority on illumination. With the mission to improve the lighted environment by bringing together those with lighting knowledge and by translating that knowledge into actions that benefit the public.
The Illuminating Engineering Society publishes and maintains the Lighting Library®, with over 100 standards written by subject matter experts.
With over 8,000 members around the world, IES is the go-to resource for anyone looking to stay up-to-date on the latest lighting design trends and best practices. With a focus on sustainability, IES is at the forefront of efforts to develop more energy-efficient lighting systems that deliver superior performance and enhance the user experience.
The mission of 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. They provide a variety of professional development, publications, networking and educational opportunities to for engineers, architects, designers, educators, students, contractors, distributors, utility personnel, manufacturers and scientists in nearly 60 countries.
Gain easy access to IES standards with ASTM Compass. With up-to-date standards available anytime and anywhere with an internet connection, you can save valuable time and resources. With the ability to download and print PDF standards, you can work even when offline.
Compass provides you one of the most comprehensive libraries of technical information available in the world including offering easy navigation through IES’s extensive collection of standards. Experience streamlined workflow and quick access to the information you need with the power of ASTM Compass.
This collection of standards includes the language and physics of lighting, vision and visual performance, color science, color appearance and rendition, photometry, non-visual effects of lighting, photobiology, lighting calculations and more.
The practice of lighting design and illuminating engineering are detailed in this collection, providing basic design principles for indoor and outdoor environments, descriptions light sources, luminaires, and control systems, lighting upgrades, lighting system commissioning, lighting economics, lighting maintenance and other aspects involved with the design, installation, and construction for lighting system.
This collection has detailed design criteria for commercial, residential, industrial, museum, healthcare, and many other applications. Each standard also includes detailed recommended illuminance criteria, laid out in clear and concise tables, all designed to guide you to design a quality lighting installation.
This collection establishes the testing and measurement standards for light sources, with the goal of providing a reliable and consistent system for calculating and measuring designed and installed illumination systems. Photometric, optical and electrical, color and color maintenance, life testing, and thermal testing are all included.
This standard covers all aspects of roadway lighting including streets and roadways, parking lots, intersections, toll plazas, tunnels, and work zones in addition to the environmental issues of light trespass and sky glow.
