Metrics in Motion: Lumen Equivalency
Presenter: Michael Myer, Pacific Northwest National Laboratory
April 2, 2019
High-intensity discharge (HID) lighting has been a staple in street/area lighting as well as high bay/warehouse lighting for more than 50 years. As LED lighting displaces HID sources in these applications, many end users seek guidance about specifying LED products. Municipalities, energy efficiency groups, and manufacturers often provide look-up tables specifying HID lamp type, HID lamp wattage, and the suggested LED streetlight fixture lumen output. These values differ significantly among the different look-up tables even for the same HID lamp type and wattage. This webinar will provide an overview of a methodology for determining LED streetlight lumens for new fixtures, along with a review of comparative light loss factors and other considerations for HID and LED sources. The webinar will also review similar considerations for high-bay applications, and briefly touch on LED replacement lamps for HID lamps.
Michael Myer has been with PNNL just under 11 years. Prior to joining PNNL, Michael worked as an architectural lighting designer in New York. Michael became an architectural lighting designer after completing his M.S. in Lighting from Rensselaer Polytechnic Institute and his B.A. in Theatre from Arizona State University. Since joining PNNL, Michael has worked on a wide-ranging number of lighting projects, field evaluations, and demonstrations for a variety of DOE programs including Building Energy Codes and Federal Appliance Standards, Commercial Building Integration, and Advanced Lighting/Solid-State Lighting.
