Unit Definitions & Metrology Context

The SI unit of illuminance is the lux (lx), which equals one lumen per square meter (1 lx = 1 lm/m²). It quantifies the intensity of light falling on a given surface.

About Lux (lx): Lux (lx) is a unit in the Illuminance measurement category. It is widely used in si standard illuminance (1 lumen/m²). The lux (lx) serves as the primary reference base unit for the illuminance domain.

About Nox (nox): Nox (nox) is a unit in the Illuminance measurement category. It is widely used in night vision & astronomy optics (1 millilux). Relative to the illuminance base unit, 1 nox equals 0.001 Lux (lx).
