NettetIlluminance is calculated with the following formula: Lux [lx] = luminous flux [lm] / area [m2]. The illuminance is 1 lux if a luminous flux of 1 lumen falls uniformly on an area of 1 m². Another formula for calculating illuminance at greater distances is as follows: Lux [lx] = luminous intensity [cd] / radius or distance squared. The further ...
