A Note About CALiPER and Laboratory Accreditation

CALiPER is not a testing laboratory or an accreditation organization. DOE established the CALiPER program to provide accurate and comparable data on LED products by arranging for reliable independent testing and data reporting of commercially available products. The CALiPER program established a process for qualifying testing laboratories to do this testing during the period when appropriate test standards such as LM-79 were under development and not yet covered by nationally recognized accreditation processes.

Laboratories Contracted for CALiPER LM-79 Testing

Additional CALiPER testing may also in some cases be performed at NIST (National Institute of Standards and Technology) or at PNNL (Pacific Northwest National Laboratory), or at appropriately accredited manufacturer laboratories.
