Dimming LEDs: What You Need to Know

This December 10, 2012 webcast presented information on the challenges and opportunities facing users trying to dim LED light sources today, reviewing the major types of deployed dimming technologies and equipment and some of the factors that lead to performance problems and incompatibilities. Michael Poplawski of Pacific Northwest National Laboratory walked through examples of what can go wrong when trying to implement dimming in common lighting applications with various types of commercially available LED light sources and controls. He also provided an update on the activities of a number of industry and government bodies that are addressing LED light source dimming, and discussed how to develop best practices to improve the prospects for successfully dimming LEDs.
