The CALiPER (Commercially Available LED Product Evaluation and Reporting) program was launched by DOE in 2006 to support testing of a representative array of solid-state lighting products for general illumination, using industry-approved test procedures carried out by qualified test labs. The program has evolved right along with the SSL market and serves multiple needs. CALiPER testing and analysis identify trends, indicate SSL's suitability for particular applications, and detect secondary issues that require further scrutiny – such as glare, flicker, physical format, and reliability concerns. The program not only guides DOE planning and helps discourage low-quality products and inflated claims, but also serves as a useful tool for manufacturers seeking to improve their products, and for municipalities, utilities, and energy-efficiency programs seeking to make informed program decisions.
Product Testing and Reporting
CALiPER testing results, summaries, and analyses are widely shared via reports, webinars, videos, presentations, and other means.
- Application Reports focus on specific product types and design scenarios, offering comparative analysis that puts LED performance in context relative to the overall lighting industry and benchmark technologies. This approach serves to educate the industry on market trends, potential issues, and important areas for improvement.
- Snapshot Reports use data from the LED Lighting Facts® product list to compare SSL performance to standard lighting technologies, and are designed to help retailers, distributors, designers, utilities, energy efficiency programs, and other stakeholders understand the current state of the LED market and its trajectory.
Standards Development Support
CALiPER test results and analysis are used to support the development of standards and test procedures for SSL – especially those related to complex areas such as flicker, dimming, power quality, and long-term performance. In addition, DOE hosts annual CALiPER roundtables – attended by representatives from industry, independent test laboratories, and key standards-setting groups – to solicit input on test results and procedures and additional testing needs for SSL.
