IES Webinar: Modern Outdoor Lighting in the Court of Public Opinion

November 13, 2023

Effectively Lighting our Outdoor Spaces

A lot has changed since the first “illuminating engineers” shared ideas for how lighting could make the early 20th century streets safer; we know more about light, we know more about vision, we know more about humans, we know more about behavior, and we know more about darkness. However, the complicated relationship between science and social media means that effectively lighting our outdoor environments may seem more challenging now than it has ever been. This presentation will align illumination science with our environmental considerations to present practical advice for all professionals facilitating the process toward best practice lighting solutions for people and the outdoor environment.

The Five Principles for Responsible Outdoor Lighting represent a true collaboration between DarkSky International and the IES to promote quality lighting by focusing on the basic principles of if lighting is needed, where light it is needed, the amount the light that is needed, and using light only when it is needed. Utilizing these principles in our designs, along with minimizing blue wavelengths to reduce light scatter outdoors at night, can dramatically improve the overall nighttime environment and reduce light pollution.
