Watt/Sq. cm (at 555 nm)

The watt per square centimetre at 555 nm is a radiometric unit of irradiance at the wavelength of peak human visual sensitivity. The conversion to lux uses the luminous efficacy of 683 lm/W at 555 nm, making 1 W/cm² equal to 6,830,000 lux. 


Lux

The lux (lx) is the SI unit of illuminance, measuring luminous flux per unit area. One lux equals one lumen per square metre. It is used to measure the intensity of light as perceived by the human eye falling on a surface. Typical office lighting is around 300–500 lux, while direct sunlight exceeds 100,000 lux.
