Illumination is a luminous quantity equal to the ratio of the luminous flux incident on a small surface area to its area. Luminous intensity is the amount of light energy transferred in a specific direction over a given period of time. In the SI system, luminous intensity is measured in candelas, but there are other units of measure for this physical quantity. How to use the light converter: Enter the number in the available units of light intensity in the appropriate field and press Enter. You will get all possible variants of this value in other units. Thanks to the column “Examples of illumination”, you can get an idea of what these or other numbers mean in practice.
