What is CALiPER?
DOE’s SSL Commercially Available LED Product Evaluation and Reporting (CALiPER) program independently tests and provides unbiased information on the performance of commercially available SSL products. The test results guide DOE planning for ENERGY STARĀ® and technology procurement activities, provide objective product performance information to the public, and inform the development and refinement of standards and test procedures for SSL products. DOE supports testing of a wide, representative array of SSL products available for general illumination, using industry-approved test procedures. Guidelines for product selection ensure that the overall set of tests provides insight on a range of lighting applications and product categories, a range of performance characteristics, a mix of manufacturers, a variety of LED devices, and variations in geometric configurations that may affect testing and performance. Commercially available products are purchased and then tested by one of several pr
