Project SummaryThis project examines the energy efficiency potential and viability of lighting emitting diode (LED) lighting at an underground parking garage at a major hotel in San Francisco. Light-emitting diode (LED) lights are emerging as a viable alternative for outdoor locations such as...

This report shows the incremental energy savings and demand reduction of currently available LED channel letter signs over traditional neon channel letter signs. The project assesses and verifies energy savings and demand reductions by measuring the performance of the technologies in a controlled...

This lab evaluation project evaluates the energy and demand savings of light-emitting diode (LED) lighting systems and traffic-sensitive lighting controllers in low-temperature reach-in refrigerated display cases. Additionally, LEDs may have longer life and lower maintenance costs. The LED systems...

Project SummaryReplacing the fluorescent bulbs that light frozen food and refrigerated cases in supermarkets with light-emitting diodes (LEDs) cuts electrical consumption by nearly half. In this study, 36 five-foot fluorescent lights were replaced with 60 four-foot LED light bars at a major grocery...

Project SummaryThe introduction of the low wattage ceramic metal halide (CMH) lamp and associated luminaires has created a new, efficacious lighting alternative to incandescent. This report evaluates the practical application of the CMH lamp in the retail environment. The objective of this report...

Project SummaryThe Linear LED lighting system is very similar in brightness, color, and glow to neon. However, it is much more durable, has longer life, and uses much less electricity than neon. The linear LED lighting system is comprised of mostly translucent plastic composite materials. This...

Project SummaryThis report summarizes the installation and assessment of light emitting diode (LED) luminaires at a department store in Northern California. Relying primarily on field testing, the project team conducted photometric and power measurements, as well as retailer satisfaction surveys...

The objective of this project is to investigate the demand reduction and energy savings potential of LED technology for OPEN signs over standard neon OPEN signs. The project verifies claimed energy savings and demand reductions by measuring the technology in a laboratory environment at the...

Project SummaryThis project evaluates the benefits and customer acceptance of electronic high intensity discharge (HID) ballasts in medium- and high-wattage applications, such as warehouses, gymnasiums, and big box retail stores. Benefits of electronic ballasts include increased energy efficiency,...

Project SummaryIn this project, a wireless energy management system was installed in a government office building to evaluate the demand response effectiveness of this technology. The wireless system investigated in this project used modular components which could be activated by either the...
