CALiPER was launched in 2006 to address a need for unbiased, trusted product performance information. DOE testing and analysis, conducted by qualified test labs using industry-approved test procedures, helped to discourage low-quality products and inflated claims. As a result, far fewer claims of exaggerated performance occurred, and product quality vastly improved. Early CALiPER testing also contributed fundamentally to the development of standardized photometric test methods specifically for SSL and the associated accreditation of testing laboratories.

As the SSL market matured, CALiPER continually transitioned its evaluations to the newest products and functions, such as color-tunable products and OLED-based luminaires, as well as long-term performance testing. CALiPER supported the development of new test procedures and application guidance, with DOE investigations providing data essential for understanding the most current and critical issues facing SSL.

Testing Results

CALiPER testing results, summaries, and analyses have been widely shared via reports, webinars, videos, presentations, and other means.

  • Application Reports focused on specific product types and design scenarios, offering comparative analysis that put LED performance in context relative to the overall lighting industry and benchmark technologies. Product category investigations included industrial luminaires, OLED luminaires, LED color-tunable products, LED MR16 lamps, PAR38 lamps, LED linear lamps and troffers, and retail replacement lamps. These reports educated the industry on potential issues and important areas for improvement.
  • Snapshot Reports used data from the now-defunct LED Lighting Facts® product list to compare LED performance to standard technologies and were designed to help lighting retailers, distributors, designers, utilities, energy-efficiency program sponsors, and other industry stakeholders understand the state of the LED market and its trajectory.
