The lux (symbol: lx) is the SI derived unit of illuminance and luminous emittance, measuring luminous flux per unit area. It is equal to one lumen per square meter.

The digital lux meter can measure up to 50,000 lux, approximately 5,000 footcandles. It's used for checking the level of luminescence, luminescence is a measure of the amount of light falling on a surface. It is defined as: 'the density of the luminous flux incident on a surface'.

Digital Lux Meter: Accurate & Free app measures the light intensity in two units: lux and fc (foot-candle).
1 foot-candle = 10.764 lux.
