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.

Eyes on the Road

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.

DC Complex Installs New Lighting in Garage to Reduce Crime Threat

The New York Times – Parking garages are the third most frequent place for crime in the U.S. Security professionals agree that parking garage design influences the level of crime significantly. The easiest way to deter criminal activity in preexisting structures is by installing bright, white lights, coupled with occupancy sensor controls. 

Relamping Retail

04/01/2013

LD+A – As retail stores make efforts to improve their sustainability and energy efficiency, a growing number are considering making the switch to directional LED replacement lamps. Compared to traditional halogen or incandescent sources, LED alternatives are about 75 percent more energy efficient, on average, and they last up to 25 times longer, but efficiency and long life are not enough. 

Let There Be Light

The Parking Professional – Michigan State University (MSU) has adopted a strong on-campus sustainability initiative. Adopting these standards for energy savings requires a challenging operating specification to follow, and MSU launched a major lighting overhaul in the parking garage at the Wharton Center last fall. 

From Walls to Walkways

11/01/2012

LD+A – The University of California, Davis, unveiled one of the most advanced outdoor lighting systems in the country this past June. Dubbed the Adaptive Campus Control System, it integrates over 1,600 individually addressed, dimmable LED luminaires with various applications – streetlights, wall packs, area lights, and post tops – into an advanced, wireless lighting controls network.

California’s New Title 24 Makes Smart Lighting Standard

10/01/2012

Lighting.com – The California Energy Commission recently updated its Title 24 Energy Efficiency Standards, improving what “up to code” means by 25 percent for residential buildings and 30 percent for commercial buildings. The new standards, now set to take effect July 1, 2014, introduce requirements for photosensors, occupancy sensors and multi-level lighting controls, both indoors and out, making adaptive lighting the new standard in California.
