Daylight Dividends
Russ Leslie for more information
The Daylight Dividends program provides resources to building professionals to facilitate the widespread implementation of daylighting in buildings. The program was established to build market demand for daylighting as a means of improving indoor environmental quality; to overcome technological barriers to effectively reap the energy savings of daylight; and to inform and assist state and regional market transformation and resource acquisition program implementation efforts.

Demonstration and Evaluation of Lighting Technologies and Applications ( DELTA)
Jennifer Brons for more information
We introduced Demonstration and Evaluation of Lighting Technologies and Applications (DELTA) in 1994. Since then, DELTA has evaluated more than a dozen lighting solutions in many common building types: offices, schools, stores, senior housing, and industrial facilities. DELTA publishes the results as case studies, each carefully documented to include sample specifications and dimensions. Items of interest in each case include energy use, maintenance, environmental impact, occupant acceptance, and performance.

DesignWorks
Patricia Rizzo for more information
DesignWorks provides cutting-edge lighting design solutions, effectively pairing advanced research with dynamic design concepts. Design is rooted in multidisciplinary research, and this program critically addresses the personal, environmental, and economic needs of contemporary society.

Energy Efficiency
Jeremy Snyder for more information
Our experts on lighting are transforming the market for lighting products. Through this program we speed the creation, entry, and penetration of new, energy-efficient lighting products into the commercial and residential markets. We also offer technical information, advice, and assistance to our sponsors and their customers in networking and planning activities to that end.

Light and Health
Mariana Figueiro for more information
Our work in light and health includes studies of the visual and nonvisual effects of light on human health. We're working to understand the effects of light on circadian rhythms, combat seasonal affective disorder, and improve day and nightshift productivity in the workplace. The Light and Health program bridges the gap between science and application by conducting both basic and applied research and producing educational materials.

Lighting Metrics
Mark Rea for more information
We're creating new lighting metrics--redefining the units and tools used to measure lighting quantity and quality. In order to maximize the acceptance of energy-efficient lighting systems, we must have new and better ways of measuring how good these lighting systems are. We must know not only how much light a system will produce, but also how well the light it produces will meet the needs of the people who will use it. The new metrics we develop will allow people to compare lighting products more easily so that they can choose the best for a particular application. They will also assist government regulators and lighting organizations in developing standards for future construction.

National Lighting Product Information Program ( NLPIP)
Jeremy Snyder for more information
The National Lighting Product Information Program (NLPIP) provides lighting specifiers, professionals, and consumers with manufacturer-specific information and performance data in useful formats to help them to find and use efficient, quality lighting products. NLPIP information is often not currently available or easily accessible from other sources. NLPIP is supported by government agencies, public benefit organizations, and electric utilities. To maintain objectivity, NLPIP does not accept funding from manufacturers.

Partners
Rebekah Mullaney for more information
Joining the LRC Partners program provides you with opportunities to shape the future of lighting by building relationships, networking, and participating in cutting-edge lighting research and education. Strategic planning seminars, conferences, and special events give Partners a chance to interact with LRC staff and other Partners and to discuss issues of mutual concern.

Program for the Evaluation and Analysis of Residential Lighting ( PEARL)
Jeremy Snyder for more information
Until now, there has been no independent system in place to test the performance of residential lighting products. Program for the Evaluation and Analysis of Residential Lighting (PEARL) fills this void. Backed by organizations including the National Resource Defense Council, U.S. Environmental Protection Agency, U.S. Department of Energy, and the Consortium for Energy Efficiency, PEARL’s testing program focuses on ENERGY STAR lighting products and covers both fixtures and lamps.

Solid-State Lighting
N. Narendran for more information
Solid-state lighting is the first genuinely new lighting technology in more than a century. The light-emitting diode, or LED, is well established as an energy-saving light source for use in indicators and signals, but it has the potential to do more. Our Solid-State Lighting program leads the way in developing solid-state lighting for general illumination applications.

Transportation Lighting
John Bullough for more information
Our Transportation Lighting group conducts research to improve the roadway visibility system, which consists of fixed roadway lighting, vehicular lighting and signaling, and traffic lights and signs. We consider these components as part of the overall visibility system and work to optimize their efficiency, safety, and appearance. Our work includes research and educational programs in such disciplines as optical design, photometry, human factors, vision, product testing, and market assessment.
