METRICS IN MOTION: FLICKER & GLARE

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.

SKY GLOW COMPARISON TOOL

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). 

BRIGHT IDEA: LIGHTING TOOLKIT FOR K-12 SCHOOL DISTRICTS

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. 

TOP EFFICACY PERFORMERS: UNDERSTANDING TECHNOLOGY TRADEOFFS

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.

NGLS Connected Lighting Evaluations: What Have We Learned So Far?

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. 

TM-30: What Have We Learned in the Past Two Years?

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. 

A Technical Discussion of DOE’s Sky Glow Study, Modeling Methods, and Key Variables

August 3, 2017
