The IES Standards Committee is responsible for overseeing the process by which IES Standards are developed. As an accredited American National Standards Institute (ANSI) Standards Developing Organization, the IES must follow the ANSI Essential Requirements for arriving at consensus based standards. The Standards Committee is dedicated to ensure that the process of committee selection is fair, open, balanced, non-commercial, and provides due process for all stakeholders. There are six at-large committee members, plus the three Chairs of the Lighting Science, Lighting Practice, and Lighting Applications Advisory Panels. All members are approved by the IES Board of Directors, and there are two Board Liaisons that work with the Standards Committee on issues of policy when needed.

Susan L. Callahan
Susan received an AB in Chemistry from Vassar College and an MS in Materials Engineering from Rensselaer Polytechnic Institute. Her thirty-odd year lighting career, started at GE Lighting and included both OSRAM and LEDVANCE (with a minor detour to do some rocket science). Her career path was vertically integrated, if not always linear. She started with analyzing raw materials and progressed to process improvements and project management. It was in OSRAM SYLVANIA’s Automotive Division that she designed her first lamps (halogen and high intensity discharge) and was awarded her first patents. She went on to General Lighting to do research and development of HID lamps. Her last ten years have been spent in standards development and regulatory affairs. Over the course of her career, Susan has served, in various capacities, on ASTM (C14), ANSI (C78, C82), IEC, CSA, and NEMA committees and was an integral part of a larger team that oversaw all lighting related standards and regulations. She looks forward to being part of the process that delivers lighting consensus standards as this aligns with her areas of expertise and builds on the work and relationships that she values.
