Corrected Unified Glare Rating (UGR) for classroom lighting less than 14
In accordance with Section 10.0 of IESNA LM-79, IES Approved Method For The Electrical And Photometric Measurements Of Solid-State Lighting Products, the light intensity distribution was measured. The theoretical Corrected Unified Glare Rating (UGR) was then calculated according to CIE 190:2010, Calculation and Presentation of United Glare Rating Tables for Indoor Lighting Luminaires. Room dimension: X = 4.35H, Y = 3.5H; Spacing to height ratio (S/H) = 1.42 (endwise) & 1.36 (crosswise); Reflectance (Ceiling/Wall/Floor) = 70%/50%/20%; Where, H= 2m
