A method, based on the formation of LED pairs with complementary characteristics, is presented to produce LED‐based light sources with narrow CCT, LOP, and VF distributions. A weighted matching algorithm was developed to select LED pairs under a multiple selection criteria. Based on the weighted matching algorithm, 96 LEDs were combined to form 48 LED pairs, and it was experimentally demonstrated that the variance of LED CCT and LOP distributions decreased by 93% and 71 %, respectively. %Z https://katalog.ub.uni-leipzig.de/Record/ai-49-aHR0cDovL2R4LmRvaS5vcmcvMTAuMTg4OS9qc2lkMTkuNi40MzE %U https://katalog.ub.uni-leipzig.de/Record/ai-49-aHR0cDovL2R4LmRvaS5vcmcvMTAuMTg4OS9qc2lkMTkuNi40MzE
