The California Energy Commission’s Public Interest Energy Research (PIER) Program through the California Lighting Technology Center funded development of a bi-level parking garage luminaire that integrates state-of-the-art induction sources and occupancy-based dimming controls.
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.
Six private offices and 44 open cubicle spaces on the ninth floor of the University of California Office of the President Franklin Building in Oakland, CA, received an IOLS retrofit in 2009. This site was selected because it provided a large, open office space, a high-occupant density, and expected long-term employee occupancy in the space.
The Department of Motor Vehicles (DMV) implemented the IOLS in a planned multiyear renovation of its 520,000-square-foot headquarters in Sacramento, CA. The original lighting goal was to provide more uniform task lighting and higher visual comfort. Original designs fell short of these goals. The IOLS, in contrast, met design objectives and increased energy savings.
The Bidwell Mansion Visitor Center (BMVC) was retrofitted in two installments. The first phase focused on the foyer and restroom, where 16 LED recessed downlights were installed. In the foyer, 14 downlights with a 10" aperture that operated with two 13 W bi-pin CFL lamps and magnetic ballasts were replaced. In the bathroom, a 3' T12 fluorescent strip light was replaced. Before the retrofit, illuminance levels, at grade, varied from about 1 footcandle (fc) to 25 fc. Average maintained illuminance levels for the foyer and restroom were 14 fc and 9 fc.
University Office of the President – The California Lighting Technology Center at the University of California, Davis works in partnership with industry, end users and others to improve illumination technology.
LD+A – The strategy is to foster the development of high-efficacy light sources that achieve, as much as possible, interchangeability with incandescent lighting, in terms of compatibility with electrical infrastructure and with popular lighting expectations. This article is a summary of CLTC research aimed at developing a technology-neutral Super Lamp specification for replacement of incandescent sources in the residential sector.
