How do you explain lux?

One lux (Latin for “light”) is the amount of illumination provided when one lumen is evenly distributed over an area of one square metre. This is also equivalent to the illumination that would exist on a surface all points of which are one metre from a point source of one international candle (candela).

What is the purpose of lux meter?

A lux measuring device or lux meter is therefore a device for determining illuminance. The illuminance is a value that does not refer to the light source, but to the illuminated area. The lux meter can be used to determine how much of the luminous flux emitted by one or more light sources reaches a specific surface.
