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.

UC Davis Institutional-Level Adaptive Controls for Exterior Lighting

02/24/2014

The Institutional-level Adaptive Controls for Exterior Lighting system incorporates exterior light points — pathways, building perimeters, parking lots, and roadways — into one smart, wireless system.

Originally launched as a pilot study, this system has since been installed for over 1,600 luminaires at the University of California, Davis.

Seoul Semiconductor and LEDLab Team Up with CLTC, UC Davis for 10th Annual Luminaire Design Competition

02/07/2014

This year, 2014, marks the 10th Annual Luminaire Design Competition for students enrolled in Designing with Light (DES 136 B) at the University of California, Davis. The competition gives students the opportunity to work with state-of-the-art lighting technologies and to share their designs with professionals in the lighting industry. Seoul Semiconductor and LEDLab supported the 2014 competition and provided each student with an Acrich2 LED module for use in their energy-efficient outdoor luminaire prototypes.

Solar panels, special lighting could save Woodland schools big money

01/28/2014

KCRA— Woodland Joint Unified School District has installed solar canopies with energy-efficient adaptive lighting at 10 sites throughout the district. The project is expected to save the district thousands of dollars annually in electricity costs while drastically reducing carbon emissions and serving as an example for other school districts focused on improving sustainability and the cost-effectiveness of district operations.

The Long View on Streetlight Retrofits

01/08/2014

This working paper authored by CLTC Director Michael Siminovitch urges cities and municipalities preparing for streetlight retrofits to make sure adaptive controls are included in their near or long-term plans. Installing LED technology in place of high-pressure sodium sources can cut energy use roughly in half, but adding adaptive controls further reduces energy use by an additional 30–50%.
