OLED Lighting in the Offices of Dejoy, Knauf & Blood, LLP

At the offices of the accounting firm of DeJoy, Knauf & Blood, LLP in Rochester, New York, the GATEWAY program evaluated a new lighting system that incorporates a number of different OLED luminaires. Evaluation of the OLED products included efficacy performance, field measurements of panel color, flicker measurements, and staff feedback. (July 2017)

Long-Term Evaluation of SSL Field Performance in Select Interior Projects

The GATEWAY program evaluated the long-term performance characteristics (chromaticity change, maintained illuminance, and operations and maintenance) of LED lighting systems in four field installations previously documented in separate DOE GATEWAY reports. (February 2017)

OLED Lighting in the Offices of Aurora Lighting Design Inc.

At the offices of Aurora Lighting Design Inc. in Grayslake, Illinois, the GATEWAY program conducted its first investigation involving OLED lighting. (March 2016)

LED Retrofit Project: Princeton University

At Princeton University’s Carl Icahn Laboratory, DOE’s Commercial Buildings Integration program documented the implementation of LED retrofit products for recessed troffers, linear cove lighting, and downlights – as part of Princeton’s first building-wide interior LED project. (November 2015)

LED Wall Washer Retrofit: University of Maryland

At the University of Maryland, the GATEWAY program looked at LED wall washer options for a demonstration at the Clarice Smith Performing Arts Center. Two products were initially mocked up and evaluated – a complete LED wall washer and a retrofit with an LED module. (July 2015)

LED Downlight Replacement: St. Anthony Hospital

At St. Anthony Hospital in Gig Harbor, Washington, DOE's Better Buildings Alliance conducted a demonstration of LED replacement lamps installed in existing CFL downlight sockets throughout the facility. (May 2015)

LED Recessed Downlights in the Alston & Bird Law Offices

At the Alston & Bird Law Offices in Atlanta, Georgia, DOE's Better Buildings Alliance conducted a demonstration of Next Generation LuminairesTM- recognized LED downlight luminaires installed throughout 16 floors of a high-rise office building as part of a larger remodel project. (March 2015)

SSL Adoption by Museums: Survey Results, Analysis, and Recommendations

A GATEWAY report summarizes the results of a survey of the museum community regarding conversions to solid-state lighting in museums. Responses provided real-world insight into how LEDs are being incorporated into museums, and what successes and hurdles have been encountered in the process. (November 2014)

Architectural and Theatrical Lighting: University of Florida

 At the University of Florida in Gainesville, the GATEWAY program evaluated LED architectural and theatrical lighting in four academic/performance-related spaces within the Nadine McGuire Theatre + Dance Pavilion. (July 2014)

LED Recessed Downlights: Hilton Columbus

At the Hilton Columbus Downtown hotel in Ohio, DOE's Better Buildings Alliance conducted a demonstration of Next Generation LuminairesTM-winning downlights installed in all guest rooms and suites prior to the hotel's 2012 opening. (June 2014)

Dimming LEDs with Phase-Cut Dimmers: The Specifier's Process for Maximizing Success

This report reviews how phase-cut dimmers work, how LEDs differ from the incandescent lamps these dimmers were originally designed to control, and how those differences can lead to complications when attempting to dim LEDs. Providing both general guidance and step-by-step procedures for designing phase-controlled LED dimming on both new and existing projects—as well as real-world examples of how to use those procedures—the report aims to reduce the chance of experiencing compatibility-related problems and, if possible, ensure good dimming performance. (October 2013—Updated to include information on Burden Museum demonstration, August 2014)

Color Maintenance of LEDs in Laboratory and Field Applications

This report summarizes color shift data of LED lamps used in real-world applications as well as LED products monitored by the CALiPER program in a lab environment. LED color shift is a cause of early failure for some products, especially in applications such as museum lighting, where visual appearance is critical. The report discusses the metrics used for communicating color shift, provides guidance on how to monitor chromaticity and what to look for in manufacturer warranties, and reviews the physical changes shown to lead to color shift in some LED packages.
