Proposals of the constructions of laboratory standards and sources for various applications based on electroluminescent sources are increasingly popular. This manuscript describes the research on designing the multichannel LED source for photometry. The optimized set of LEDs, composed of 25 channels, reproduces the illuminant A with a mismatch error of 1.58%.
