Intensity Definition & Meaning - Merriam-Webster

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 ... NettetIntensity does diminish by the different in areas, which is insignificant for most small moves. Conversions should only be used as a last resort, as nothing is more accurate than an actual measurement. If light intensity is the facilitator of sight, then uniformity manages the quality of what is seen.
