The IES Advisory Panels work strategically with IES Staff to determine the need for addressing new lighting topics, and in aligning committees to ensure collaboration between technical committees. The Advisory Panel members act as mentors and collaborators to the committees, guiding them through the process of developing Standards, coordinating efforts between committees, and facilitating communication with IES staff. All technical committees are grouped under these Advisory Panels according to their respective areas of lighting science, practice, and applications. Each Advisory Panel Chair also serves on the IES Standards Committee.
