DOE Releases CALiPER Application Summary Report On LED Recessed Wallwashers
October 29, 2012
The U.S. Department of Energy has completed Series 18 of testing through the DOE Solid-State Lighting CALiPER program. A summary of the results is now available for download.
Report 18 analyzes the performance of 17 LED recessed wallwasher luminaires. The products tested were diverse in luminous intensity distribution and lumen output—reflecting the varied applications in which recessed wallwashers are used—but were generally comparable to conventional wallwashers using a 32 W CFL or 20 W metal halide lamp. Several products were measured to have lumen output equivalent to 42 W CFL or 35 W metal halide lamps. As with many product categories, there is room for performance gains.
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 18 will be available soon through the searchable online CALiPER system.
