Light uniformity, also referred to as evenness of lighting, is a measure of how evenly and uniformly the light in a setting is distributed. It is also a description of the smoothness of the lighting pattern or the degree of intensity of light and dark areas in the area to be lighted. Uniform light is usually expressed as a ratio such as max to min. The lower the ratio the more uniform the lighting design.
When a person enters a new lighting environment, the pupil in the human eye automatically constricts or dilates to allow more or less light into the eye. The human eye will fully adjust itself to even lighting in a new setting, even at very low light levels. However, if an environment has uneven lighting the eye will not fully adjust and some areas will always appear darker than others. Even lighting in an environment is generally created by having many lights spread out to cover an area, as opposed to having only a few very bright lights.
