Solid-State Lighting GATEWAY Demonstration Results

The U.S. Department of Energy (DOE) shares the results of completed solid-state lighting (SSL) GATEWAY demonstration projects, publishing detailed reports and briefs on completed projects, both available as Adobe Acrobat PDFs. The reports include detailed analysis of data collected, projected energy savings, payback analysis, and user feedback.

Technology briefs profile specific SSL technologies under consideration for GATEWAY demonstrations. Download Adobe Reader.

LED Street Lighting: Lija Loop, Portland
On Lija Loop, a residential street in Portland, Oregon, eight high-pressure sodium cobra head fixtures were replaced with LED street light luminaires. Project results included an estimated payback of 7.6 years for new installations and 20 for replacement scenarios.

LED Freezer Case Lighting: Albertsons Grocery
At an Albertsons Grocery in Eugene, Oregon, upright freezer cases were retrofitted with LED striplights combined with occupancy sensors, and compared against standard fluorescent lighting on the opposite side of the aisle. Calculated payback periods approached five years from estimated energy and maintenance savings for a typical 5-door case.

LED Parking Lot Lighting: Raley's Supermarket
At a Raley's Supermarket in West Sacramento, California, several metal halide (MH) luminaires were replaced with new LED luminaires incorporating bi-level operation (dim state and full state) controlled by motion detectors. Results indicated an energy savings potential approaching 70% on an annual basis, a more uniform lighting distribution, and payback periods of less than five years.

LED Street Lighting: City of San Francisco
In the Sunset District of San Francisco, four manufacturers' LED street lights were installed on four public avenues to replace 100-watt nominal high-pressure sodium luminaires, independently demonstrating the performance of a number of currently available products in one specific application.

LED Roadway Lighting: I-35W Bridge
The I-35W Bridge in Minneapolis, Minnesota, features LED roadway lighting on the main span, offering DOE the opportunity to study the use of LED lighting in a highly challenging environment over the course of three years. Phase 1 was completed in September 2008. Phase 2, involving long-term monitoring of the LED lighting, is expected to yield valuable information on lumen depreciation, physical effects, and performance impacts over time.

LED Residential Downlights and Undercabinet Lights: 2008 Eugene Tour of Homes
LED downlights represent one of the most promising applications for SSL technology and significant energy savings. This project studied the installation of LED downlights and undercabinet lights in two "green" showcase homes in Eugene, Oregon. LED downlights are emerging as a viable energy-saving alternative to incandescent and fluorescent downlights.

LED Parking Garage Lighting: Providence Portland Medical Center (PPMC)
With an eye on replacing its aging stock of luminaires campus-wide, PPMC wanted to evaluate more energy-efficient lighting options. In this project, PPMC replaced several high-pressure sodium fixtures in the hospital parking garage with LED luminaires, enabling a side-by-side comparison of the lighting performance, quality, energy savings, and user feedback.

LED Walkway Lighting: Federal Aviation Administration (FAA) Technical Center
At the FAA Technical Center in Atlantic City, New Jersey, six modular LED luminaires were installed along exterior walkways, replacing six high-pressure sodium luminaires. Project results include photometric data, projected energy savings, payback analysis, and user feedback on perceived improved visibility.

LED Street Lighting: City of Oakland
The City of Oakland wanted to assess the energy, economic, and safety impacts of replacing high-pressure sodium (HPS) street lights with LED luminaires. This project involved installation of 15 LED street lights – ten on the LED-only street and five on the LED/HPS street.
