Lighting practitioners are often tasked with meeting multiple concurrent requirements for outdoor lighting: illuminance and uniformity requirements, energy code maximums, lighting ordinance requirements, safety, and cost effectiveness without additional burden in the specification and shop drawing review process. Photometrics underpin most outdoor lighting designs, but our tools are incomplete with regards to light pollution modeling. The presenters provided specification language, case studies and tools for specifying controllable low CCT and Amber outdoor lighting to combat light pollution, including DLC resources to help practitioners gain more confidence in their analyses, design, and selection processes.
