WebApr 10, 2024 · Luminance is the intensity that is measured on a surface at a specific position. The SI unit is candela per square meter, which is still sometimes called a nit. The color of the Luminance is a certain color that can be defined by hue (0o - 360°), saturation (0% - 100%) and lightness (0% - 100%). Web(SI units), the lux (lx) is regarded as the reference unit. Some countries use the footcandle (fc) which is not an SI unit. For this reason, this illuminance meter provides a function to display readings converted to fc units with a unit selector switch.
