Illuminance vs luminous flux
In photometry, illuminance is the total luminous flux incident on a surface, per unit area. It is a ... where Ev is the illuminance in lux, and Mv is the apparent magnitude. The reverse conversion is. M v = − 14.18 − 2.5 log ( E v ) -displaystyle .,To clarify the difference, illuminance refers to intensity of light falling onto a surface, while brightness refers to the visual perceptions and physiological ... ,Luminous flux per unit solid angle per unit projected source area. The candela per square metre is sometimes called the nit. Illuminance, Ev, lux (= lumen per ... ,Luminous flux per unit solid angle per unit projected source area.
