WebGrowing awareness of new, energy-saving lighting often overlooks the integral role of the ceiling. A high light reflectance ceiling – LR 0.83 or greater, per ASTM E1477-98 as referred to in ASTM E1264-98 – makes these lighting systems, especially indirect lighting, more effective while further reducing energy costs and consumption. WebThe ceiling is the most important light-reflecting surface; hence, the recommended reflectance values are high at 80 percent or more. Reflectance values should be at least 50 percent for walls and at least 20 percent for floors. Reflectance and Paint Sheen.
