Yes, LISUN is a manufacturer of test and measurement equipment for the lighting industry, and their goniophotometer can be used to perform the CIE 121 test. The CIE 121 test is a standard that was developed by the International Commission on Illumination (CIE) for measuring and reporting the angular distribution of luminous intensity of a light source. LISUN's goniophotometer can be used to perform this test. Both the CIE 121 test and the IESNA LM-63 test entail measuring the light output of a lighting fixture from a variety of angles; however, the CIE 121 test and the IESNA LM-63 test vary in the circumstances under which the measurements are taken as well as the criteria for reporting the results. A goniophotometer, such as the one that is manufactured by LISUN, is outfitted with a rotating stage that is able to hold the light source that is being evaluated as well as a detector that is able to measure the amount of light output at various angles.
