Directional LED Lamps – Laboratory Testing Program

12/01/2012

The retail sector constitutes one of the largest energy consumers in the U.S., and halogen parabolic aluminized reflector (PAR) and multifaceted reflector (MR) lamps are common retail lighting choices. LED replacement lamps have the potential to transform lighting energy use in this sector, and manufacturers of LED PAR and MR lamps now claim comparable photometric performance, as well  as much greater longevity, than traditional halogen lamps.

UC Davis Smart Lighting Initiative: Lighting the Way to a Sustainable 2nd Century

05/01/2012

Lighting accounts for about a quarter of California’s electricity use, and installing energy-efficient lighting can lead to significant energy, maintenance, carbon, and economic savings, according to the California Public Utilities Commission (CPUC). In September 2010, the CPUC adopted a plan to achieve a 60–80% reduction in statewide electrical lighting consumption by 2020.

Philips Energy Advantage CDM lamps with AllStart

06/01/2011

Philips Lighting has released a ceramic metal halide, direct-retrofit lamp that can be used with both probe- and pulse-start ballasts. The Philips Energy Advantage CDM lamp with AllStart Technology saves energy, improves efficacy and color rendering, maintains light levels, and is more affordable than traditional metal halide (MH) lamps. Philips says the lamps “provide true universal operation regardless of orientation without compromising light quality, and make installation and maintenance easier than ever.” 

Advanced LED Downlights

05/01/2010

Lighting California's Future – The Advanced LED Downlights project takes downlights in a whole new direction—up! The LCF project partners developed a dimmable downlighting system based on indirect optical design that reduces glare, decreases installation time, averages LED color variations and improves thermal management. 

Wireless Integrated Photosensor and Motion Sensor

08/01/2010

Lighting California's Future – Lighting controls systems are readily available in the market that turn lights off when spaces are unoccupied or when sufficient daylight is available. However, installing these systems involves new wiring or rewiring and can be an expensive proposition to retrofit existing buildings. Adura Technologies, in partnership with the California Lighting Technology Center, developed a wireless integrated photosensor and motion sensor system that communicates wirelessly through radio frequency to circumvent this issue. 

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. 

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.
