   Illuminance
   In photometry, `illuminance` is the total luminous flux incident on a surface, per unit area. It is a measure of the intensity of the incident light, wavelength-weighted by the luminosity function to correlate with human brightness perception. Similarly, `luminous emittance` is the luminous flux per unit area emitted from a surface. Luminous emittance is also known as `luminous exitance`. In SI derived units, these are both measured in lux (lx) ...

   illuminance
   illuminance The amount of light, evaluated according to its capacity to produce visual stimulation, that reaches a unit of surface area during a unit of time. It is measured in lux (the SI unit of illumination, equal to one lumen per square meter). A lumen is the unit of luminous flux in the International System, equal to the amount of light given out throu...

    illuminance
    Also known as luminous flux density, the total amount of visible light falling on a point on a surface from all directions above the surface in a given time. It is equivalent to irradiance weighted with the response curve of the human eye. Illuminance is measured in lux (lx), or lumens per square me...
