Solid-state lighting (SSL) technologies today are changing and improving rapidly, and products arriving on the market exhibit a wide range of performance. There is a need for reliable, unbiased product performance information to foster the developing market for high-performance SSL products.
The DOE Commercially Available LED Product Evaluation and Reporting (CALiPER) program supports testing of a wide array of SSL products available for general illumination. DOE allows its test results to be distributed in the public interest for non-commercial, educational purposes only. Detailed test reports are provided to users who provide their name, affiliation, and confirmation of agreement to abide by DOE's NO COMMERCIAL USE POLICY.

About the CALiPER Program
Analysis of CALiPER test results and feedback from lighting manufacturers, efficiency programs, and utilities guide DOE planning for the CALiPER program. Learn more about the CALiPER program, including details about the CALiPER guidance committee and the CALiPER Roundtable report.
For more information on the CALiPER product selection process, test procedures used, accredited testing laboratories, and other issues related to CALiPER testing, see Frequently Asked Questions.
DOE publishes CALiPER Summary Reports following completion of a testing series, and starting in 2012, each 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.

Detailed Test Reports
Detailed Reports provide extensive data on individual products tested through the CALiPER program and are distributed in the public interest for non-commercial, educational purposes only. Detailed Report information can be accessed through an online system with both basic and advanced search options.
CALiPER Benchmark Reports, published periodically, provide detailed analysis of test results for both traditional (non-LED) and LED products for a given application, comparing a range of standard lighting measures. Download CALiPER Benchmark Reports.
The DOE CALiPER Program conducts and publishes advanced exploratory studies on issues related to testing of lighting technology and applications. Download CALiPER Exploratory Studies.
