Quality control is one of the main functions of the quality management process. Its purpose is an identification of production errors for their prompt elimination and with minimal production losses. The launch of the concept of quality assurance into practice has significantly increased the efficiency of production with a sufficiently high quality of products and services, which has created conditions for the formation of a global market for goods and services. For LED lights luminous flux is the basic parameter that is needed to calculate the illumination of things and to understand the basic parameters of the suitability of the LED lights. In the analyzed articles, the specific time of the beginning of measurements of the luminous flux of the lamp is not given, which is a source of data discrepancies and erroneous results of calculating its light output. Therefore, to eliminate this deficiency in the technical characteristics, the luminous flux should be reduced after a certain stabilization time after power supply. To solve the problem associated with the development of standards for determining the level of degradation of the luminous flux, in this article the technique for predicting the decline of the luminous flux of a LED lamp through the determination of the level of decline in illumination is developed and the approximation of curves is presented.
