Document Summary

Lighting that provides illumination to special object like sculptures. Type of lighting where 90- 100% of light output is directed to ceiling or upper walls. Lighting used primarily to draw attention to particular points of interest. The luminous flux emitted per unit solid angle by a light source, expressed in candelas. A unit of luminous intensity used prior to 1948 equal to the luminous intensity of a wax candle of a standard specifications. The basic si unit of luminous intensity equal to the luminous intensity of a source that emits monochromatic radiation. The rate of flow of flow visible light per unit time expressed in lumens. The si unit of luminous flux equal to the light emitted in a solid angle of one steradian by a uniform point source having an intensity of one candela. The si unit of illumination equal to one lumen per square meter.
