WebFeb 22, 2024 · Illuminance is the metric that is used to measure the light intensity within a space. It is measured in footcandles or lux – it is the amount of light (lumens) falling on a surface (over any given square foot or square meter). Therefore, light intensity is measured in terms of lumens per square foot (footcandles) or lumens per square meter (lux).
