DOE Releases CALiPER Application Summary Report on LED Linear Pendants
November 7, 2012
The U.S. Department of Energy has completed Series 19 of testing through the DOE Solid-State Lighting CALiPER program. A summary of the results is now available for download.
Report 19 reviews the independently tested performance of nine LED linear pendants and also evaluates a supplemental collection of 11 linear pendant products available in both an LED and fluorescent version. In general, the LED versions were more efficacious, but sometimes had a different luminous intensity distribution, poorer color quality, or different lumen output than their fluorescent counterparts. Specifiers should note that fluorescent and LED versions of the same product are not always interchangeable.
Beginning in 2012, each CALiPER summary report focuses on a single product type or application. Products are selected with the intent of capturing the current state of the market—a cross section ranging from expected low- to high-performing products—with the bulk characterizing the average of the range.
The Department allows detailed test results from CALiPER testing to be distributed in the public interest for noncommercial, educational purposes only. Detailed test results for Series 19 will be available soon through the searchable online CALiPER system.
