Project Summary:This study evaluated an emerging technology that potentially provides energy efficiency improvements on HID lighting. The main objectives of this assessment were 1) to evaluate energy use of the emerging technology as compared to the existing technology, and 2) to characterize the...

Project SummaryThis report summarizes an assessment project conducted to study the performance of light emitting diode (LED) luminaires in a street lighting application. The project included installation of four manufacturers’ LED street lights on public roadways in San Francisco, California....

The MR16 is a standard format for halogen light sources. The term MR16 stands for ‘multifaceted reflector’ and 16 eights of an inch diameter. The mirror reflector in the MR16 allows the light to be directed from the small halogen filament in a highly focused beam with little spill light. MR16 lamps...

Project SummaryThis report summarizes the installation and assessment of electronic HID at a regional supermarket chain location in Northern California. Relying primarily on field testing, the project team conducted photometric and power measurements, as well as customer satisfaction surveys and...

Project Summary:This report summarizes an LED street lighting assessment project conducted to study the applicability of LED luminaires in a street lighting application. In this project, LED lights replaced regular high pressure sodium (HPS) streetlights on several streets in Oakland, California....

This project assesses the energy and demand savings potential of LED technology in residential downlighting applications through lab evaluations and field monitoring of actual kitchen usage...

Project SummaryThis report summarizes the third phase of an LED street lighting assessment project conducted to study the applicability of LED luminaires in a street lighting application. In Phase II, fifteen 78-watt LED luminaries replaced a like number of 121-watt high-pressure sodium (HPS)...

The objective of the lab evaluation project is to assess the incremental energy savings and demand reductions of using LED SDLs over incandescent and fluorescent PAR30 floodlight lamps. Screw-in Directional lighting, or Screw-In Directional Lamps (SDL), refer to lamps with halogen, fluorescent, or...

This project is aimed at evaluating Bi-level Hybrid Fluorescent LED Lighting for Stairwells and Covered Parking as an energy efficiency measure. The project will field test fixtures to determine the potential for energy...

Project SummaryLight-emitting diode (LED) lights are emerging as a viable alternative for outdoor locations such as parking lots, parking garages, and streets, which typically use wallpaks and bollards lit with high wattage, high intensity discharge (HID) or fluorescent lights. In addition to...
