- As aforementioned, illumination is the property and effect of light in an observable form, presenting the use of light sources. By contrast, illuminance measures how much luminous flux is spread over a given area. Luminous flux, which is measured in the unit of lumens, can been considered as the measurement of how much visible light present in ...

- Illumination (illuminance), E, is the _areal density_ of incident luminous flux: how many lumens per unit area. A lumen per square foot is a foot-candle; a one square foot area on the surface of a sphere of radius one foot and having a one candle point source centered in it would therefore have an illumination of one foot-candle due to the one ...

- The lux (symbol: lx) is the SI derived unit of illuminance, measuring luminous flux per unit area. It is equal to one lumen per square metre. In photometry, this is used as a measure of the intensity, as perceived by the human eye, of light that hits or passes through a surface. It is analogous to the radiometric unit watt per square metre, but with the power at each wavelength weighted ...

Luminance - Wikipedia
- https://en.wikipedia.org/wiki/Luminance
- Luminance is a photometric measure of the luminous intensity per unit area of light travelling in a given direction. It describes the amount of light that passes through, is emitted from, or is reflected from a particular area, and falls within a given solid angle.. Brightness is the term for the subjective impression of the objective luminance measurement standard (see Objectivity …
