Communities and local governments want lighting solutions that allow them to meet outdoor lighting ordinances and achieve their decarbonization goals while juggling challenges associated with inconsistent lighting nomenclature and performance metrics. Concurrently, LEDs with non-standard chromaticities —especially phosphor-converted Amber LEDs—are gaining popularity as a strategy for mitigating light pollution, and do not have standard lighting specification language. In this talk, we will discuss the importance of reducing light pollution, describe a specification structure for non-white LEDs, provide an LED performance comparison, give an update on the ANSI C78.377 chromaticity standard, and describe additional resources for evaluating outdoor luminaires.
Attendees should understand spectrum characteristics such as spectral power distributions and chromaticity coordinates as well as photometric analyses.
- Learning Objectives
Participants will gain a deep understanding of the negative impacts of light pollution and how to combat it. - Participants will learn of a series of resources for specifying non-white light fixtures
- Participants will understand the difficulties in specifying non-white light and will be given a specification framework that can be used immediately
- Participants will be abreast of the latest standards development work underway (specifically ANSI C78.377)
