Popis: This research examined human subjective responses to small, high-luminance light sources against low-luminance backgrounds and evaluated performance of four discomfort glare models. Forty-seven observers evaluated 36 conditions including three glare source luminances (20,000, 205,000, 750,000 cd/m2), two source positions (0°, 10°), two source sizes (10−5, 10−4 sr), and three background luminances (0.03, 0.3, 1 cd/m2) on a seven-point rating scale of perceived glare. The Unified Glare Rating (UGR) small source extension had the highest correlation with subjective responses (r = 0.879, P
