WebThe candela, symbol cd, is the SI unit of luminous intensity in a given direction. It is defined by taking the fixed numerical value of the luminous efficacy of monochromatic radiation … WebLux (luminous intensity) = lumen per square metre also adds linearly. If you has say 3 LEDs (each of say 1200 lumen output), each exactly and uniformly illuminating a 1m x 0.5 m area and you placed the areas side by side to make a single 1m x 1.5m area, then. Each sub area would have a luminous intensity of 1200/0.5 = 2400 lux.
