The CALiPER program of the U.S. Department of Energy has established a process for qualifying testing laboratories that are capable of providing accurate and comparable performance data for solid state lighting, including LM-79 reports for LED streetlight luminaires.
The LM-79 report involves test and verification of total light output, voltage, current, power, efficacy, lumen distribution, CCT, CRI, and spectral distribution of a solid state light, The report also provides information about the testing lab and equipment used to perform the tests.
