Below you'll find links to information about past webcast presentations related to solid-state lighting, including presentation slides and question-and-answer sessions, where available.
July 11, 2019
A presentation that provides an up-to-date evaluation of progress in addressing critical lighting quality factors, their implications for energy-efficient LED lighting, and where additional research is needed.
November 8, 2018
A presentation that described and demonstrated use of the Sky Glow Comparison Tool, a simplified method for comparing contributions to sky glow among lighting products by using various combinations of output characteristics (e.g., spectral content, light output level, percent uplight).
November 6, 2018
A presentation that introduced comprehensive guidance for K-12 schools along with a review of the newest lighting technologies and strategies for classroom optimization and proficiency, with a goal of helping school energy managers use the best available applications for their schools. To assist with decision-making during the lighting upgrade process, presenters reviewed technologies such as tunable lighting, controls, and troffer retrofits, offering economic snapshots for the benefits of these upgrades. While focused on K-12 schools, this toolkit can be useful for multiple building types.
October 25, 2018
A presentation that examined key findings from a 2018 DOE study entitled "An Investigation into high-achieving LED luminaires." The purpose of the study was to evaluate the performance of several LED lighting products with claimed efficacies near or exceeding 200 lumens per Watt, and the webinar looks at tradeoffs between efficacy, lumen output, light distribution, color temperature, and visual comfort in those luminaires.
February 13, 2018
A presentation about lessons learned to date from Next Generation Lighting Systems (NGLS) competitions 1 and 2, including an inside look at the challenges encountered in the installation and configuration of these lighting systems in working classrooms.
September 12, 2017
A presentation about the latest research on TM-30 – including studies relating TM-30 values to human evaluations and the specification criteria that can be derived from the results – as well as the future of TM-30 and color rendition measures.
August 3, 2017
The second part of a two-part presentation about the DOE sky glow study that provides a deeper dive into the modeling effort as well as the influence of individual variables.
July 27, 2017
A high-level overview of the DOE sky glow study and its findings, to put them into a context of typical street lighting conversions taking place in the U.S. today.
October 20, 2016
A presentation on key issues underlying concerns raised by the American Medical Association community guidance on street lighting, and their applicability to LED street lighting.
October 18, 2016
A presentation about a pilot study of LED lighting systems in preparation for a planned expansion and renovation at a Sacramento senior-care center.
October 4, 2016
A presentation on a major literature review summarizing published evidence for the benefits of high-quality healthcare lighting reported in recent research.
September 13, 2016
A presentation on SSL technology and healthcare lighting, with insights from a survey of 252 nurses on patient room lighting.
July 28, 2016
A presentation on a new DOE market study of OLED lighting products.
October 22, 2015
A presentation on the current state of connected outdoor lighting system technology and where it is heading.
September 22, 2015
A presentation on why and how TM-30-15 advances light source color rendition metrics.
September 15, 2015
A presentation on the basics of TM-30-15, a new method for evaluating light source color rendition.
March 26, 2015
A presentation on DOE's GATEWAY demonstration of LED architectural and theatrical lighting at the University of Florida.
