PIER-sponsored research, development, and demonstration has focused on the combination of occupancy-based lighting controls and broad-spectrum light sources to create intelligent, bi-level luminaires designed for street and parking area applications. These products achieve 30 – 75% energy savings compared to traditional street and area luminaires, meet stringent energy-efficiency standards, and provide excellent light distribution for reduced night sky pollution.
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.
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.

This presentation will include an overview of the lighting research activities at the California Lighting Technology Center with a focus on demonstrations, commercialization, and integration within the codes and standards process.
The primary objective of this study is to quantify the energy use in private offices that are equipped with bi-level switching and occupant controls. The baseline comparison is made to a theoretical case where the occupant has no control over their lighting and it is switched on and off solely by an occupancy sensor. In addition, this study looks closely at the possibilities for combining automatic and manual control to achieve the greatest energy savings and user satisfaction.
