The U.S. DOE has completed Round 12 of product testing through the DOE Solid-State Lighting (SSL) CALiPER program. A Summary Report containing the results from Round 12 testing is now available for download on the DOE SSL website at www.ssl.energy.gov/reports.html. Round 12 of product testing included six primary focus areas: SSL recessed downlights, SSL track lights, SSL A-lamps, benchmark 100W incandescent A-lamps and 70-100W halogen equivalents, SSL replacements for linear fluorescent lamps in high-performance troffers, and SSL and benchmark cove lights. The Round 12 Summary Report provides an overview of photometric performance results, and discusses the results with respect to similar products that use conventional light sources, results from earlier rounds of CALiPER testing, and manufacturer ratings.
