DOE Publishes the Latest Round of LED Test Results

The Commercially Available LED Product Evaluation and Reporting (CALiPER) program is available which provides an ongoing series of “snapshots” of solid-state lighting (SSL) technology progress and trends. The  Round 9 Summary Report includes test results for recessed downlights, 2’x2’ troffers and flat-panel luminaires, 4’ linear replacement lamps, and small replacement lamps. Just as in previous rounds of testing, Round 9 products exhibited a wide range of performance, with a number of underperforming products and inaccurate performance claims. Most notably, the results for CALiPER Round 9 show that for applications like downlights and 2’x2’ troffers, many SSL products are now clearly competitive with incumbent technologies.
