Citing energy savings between 40 and 50 percent with matching light levels and quality, a report published by the U.S. General Services Administration’s (GSA) Green Proving Ground (GPG) program recommended plug-and-play LED downlight lamps as a replacement for compact fluorescent lamps. Plug-and-play LED downlights used for this evaluation were provided by Lunera Lighting.
In 2014, plug-and-play LED downlights provided by Lunera were selected from more than 120 candidates to participate in real world testing through the GPG program. Last month, GSA released findings from a one-year evaluation in three federal buildings, by independent research lab Pacific Northwest National Laboratory (PNNL).
PNNL assessed the light levels, energy and cost savings over time and determined that payback for the plug-and-play LED downlights was 2.4 years compared to 12.4 years if installing or retrofitting a LED fixture.
LED light levels in the plug-and-play downlights were better than or equal to measurements taken in the previous lamps. In addition, the occupants and facility managers of the test buildings were interviewed after a year of working under LED lighting and had not noticed any difference according to the report.
Standard compact fluorescent downlights were replaced with Lunera’s plug-and-play LED Lamps in the U.S. General Services Administration’s regional headquarters in Auburn, Washington; the Cabell Federal Building in Dallas and the Veterans Administration Center in Philadelphia for this study.
Findings mentioned in this press release are based on the report, “LED Downlight Lamps for CFL Fixtures,” and are available from the GPG program website.
