• The DOE has completed Round 13 of product testing through its CALiPER (Commercially Available LED Product Evaluation and Reporting) program. This latest round focused on LED and benchmark high-bay luminaires, LED wallpacks, and LED and benchmark 2-foot-by-2-foot troffers. The summary report can be downloaded here.
  • The DOE has published the findings of two recent Gateway demonstration projects. The first, Demonstration Assessment of Light-Emitting Diode (LED) Roadway Lighting,” reports on a roadway lighting installation along a portion of the FDR Drive in New York City. The project, done in conjunction with the New York City
  • Department of Transportation and the Climate Group, evaluated four different types of LED roadway luminaires in comparison to existing high-pressure sodium (HPS) fixtures: The LED fixtures provided a 26 to 57 percent energy savings. Three of the LED roadway lights equaled the initial illuminance of the HPS luminaire, but only two met the required maintained illuminance level described in Illuminating Engineering Society RP-8-00 (ANSI Practice for Roadway Lighting). The LED luminaires did provide better color rendering and emitted no uplight.

    The other Gateway demonstration report—Assessment of LED Technology in Ornamental Post-Top Luminaires”—examines a test case in Sacramento, Calif., conducted by the DOE Municipal Solid-State Street Lighting Consortium, in conjunction with the Sacramento Municipal Utility District and the City of Sacramento. Four different LED replacement luminaires were evaluated, limited to lamp-ballast retrofit kits and complete luminaire replacements that would maintain the daytime appearance of the existing acorn-style streetlights. None of the LED products matched the performance of the 100W HPS luminaires. Both reports are available here.
