Measuring lux with the photometer – how does that work?

The luminous power (unit: lumen) between a light source and the area illuminated by it is measured using the lux (lx) unit. The illuminance is exactly one lux when luminous power of one lumen (lm) uniformly illuminates an area of one square metre. A lux measuring instrument is referred to as a lux meter or also as a photometer.
