Course Overview

The new Illuminating Engineering Society of North America (IES) RP-8-14 Recommended Practice for Roadway Lighting has changed to the Luminance design method as the primary design method. The new RP-8. also has new guidance related to LED lighting, Adaptive Lighting and Lighting for Pedestrians. Learn the basics of lighting design, design methods and guidelines with this course.
