The lux (symbol: lx) is the unit of illuminance, or luminous flux per unit area, in the International System of Units (SI). It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre, but with the power at each wavelength w… WebA lux (lx) is the SI unit of illuminance and luminous emittance, measuring luminous flux per unit area. One lux is equal to one lumen per square meter: 1 lx = 1 lm/m² = 1 cd·sr·m⁻². meter-candle A meter-candle (m·cd) is a metric unit of illuminance and luminous emittance, measuring luminous flux per unit area.
