The results of investigation of luminous intensity distribution and color quantities of LED lamps of different design are presented. It is demonstrated that measurement of angular luminous intensity distribution is more accurately indicates characteristics of LED lamp emission than measured luminous intensity value alongside its mechanical axis. It is established that color quantities of investigated LED lamps declared by manufacturer are different from values defined by applicable normative documents.
