Lux is used in measuring luminous flux per unit area.
The lux is the SI unit of illuminance, and is equal to 1 lumen per square meter.
A lux (lx) is the SI unit of iluminance, or light intensity as seen by the human eye.
LUX is the measurement of illuminance and luminous emittance from light sources.
Sunlight typically provides around 100,000 lux of brightness on a clear day. Lux is a unit of measurement for illuminance, or the amount of light that falls on a surface.
Candela (cd).
Lux is a measure of illuminance, or the amount of light hitting a surface. Watts, on the other hand, are a measure of power. The relationship between watts and lux depends on the characteristics of the light source and the distance from the source to the surface. In general, there is no direct conversion between watts and lux.
