Illuminance means the unit measure of light at a surface.
Illuminance means the amount of light that is incident to the surface of the sign. This is the method for describing ambient light levels or the amount of light that is projected onto a front-lit sign. This is typically measured in footcandles.
Illuminance means the level of light measured on an
Illuminance means the amount of light falling upon a real or imaginary surface, commonly “light level” or “illumination,” measured in foot candles (lumens/square foot) in the English System, and lux (lumens/square meter) in the SI (metric) system.
Illuminance means the intensity of light falling on a surface, measured in lux;
Illuminance means the amount of light that is intercepted by an object that is a distance away from the Sign measured in Footcandles. That is, the lighted Sign face illuminates objects that are away from it, and the lighting level produced by the Sign on a particular object is measured in Footcandles.
Illuminance means the photometric quality most closely associated with the perception of brightness and a measurement of the intensity of light falling on a surface at a given distance from the light source. Illuminance can be measured with a footcandle meter, also known as a luxmeter.
