High Color Rendering Can Enable Better Vision without Requiring More Power

03/02/2015

LEUKOS— A new article advocating for high color rendering in consumer lighting products and the policies that support their adoption is now available. The paper is a collaboration between CLTC, the University of British Columbia and the National Research Council of Canada.

The article focuses on the tradeoff between color rendering accuracy and lamp efficiency to show that high color rendering accuracy is appropriate and, contrary to a common misconception, does not intrinsically require greater electrical energy consumption.

LD+A Research Matters: Core Concepts

05/01/2011

LD+A— Core sunlighting is a practical, natural alternative for interior illumination deep within a building. Unlike other solar technologies, core sunlighting involves capturing sunlight at the building envelope, concentrating it, transporting it and regulating its release deep within the building at useful indoor lighting levels, typically only 1 percent of outdoor illumination. Significant electrical energy savings can be realized if the system incorporates automated electric lighting controls that substantially dim or completely turn off the electric lights.

LD+A Research Matters: Shedding More Light on Occupancy

09/01/2014

LD+A – Multiple studies have demonstrated the significant energy savings that bi-level, occupancy-based lighting controls can achieve in outdoor applications. These controls maintain recommended illumination levels during occupied periods and automatically dim lights, reducing power by 50 percent or more, during vacant periods.

'Greening' Construction Jobs for Energy Efficiency

LD+A Research Matters: LED Retrofit Options for Linear Fluorescent Lighting

03/01/2014

LD+A – Tubular fluorescent lamps comprise 80 percent of the lamp inventory in the commercial sector, or about 1.7 billion lamps, according to a U.S. Department of Energy report. As the lighting industry moves rapidly toward solid-state lighting, three main LED retrofit strategies have emerged for this very large segment of the market: tubular LED lamps, LED retrofit kits and dedicated LED luminaires.

LD+A Research Matters: In Pursuit of Automated Demand Response

11/01/2013

LD+A – CLTC and Berkeley Lab partnered to test the ADR-readiness of commercially available networked lighting control systems. All three systems tested were configured for automated demand response (ADR) communications, and all three successfully accessed the demand response automation server (DRAS) to retrieve DR events.

LD+A Research Matters: Eyes on the Road

08/01/2013

LD+A – CLTC researchers incorporated passive infrared (PIR) occupancy sensors and networked controls into a test set of dimmable LED roadway fixtures. The adaptive street lighting system yielded energy savings 27 to 42 percent greater than when the fixtures operated at a static level. All occupants, 100 percent, were detected by the PIR occupancy sensor selected for field testing, whether they were traveling on foot, by bicycle, on a motorcycle, or in an automobile.
