Easy to understand graphic explaining the difference between lux and lumens as well as a conversion calculator.
Lux - Unit of Illuminance The number of lux indicates how much light falls on a surface, expressed in lumens per square metre. This light can come from anywhere: a lamp, sunlight coming in through a window, reflections on walls, and so on. To extend our water analogy, illuminance in ...
the luminous flux is the same, which is 100 lumens, but the area over which the light spread has changed. Therefore, the illuminance at 2 meters is one fourth of the value at 1m, which is 25lux. Further away the illuminance is even lower. ...
The lumen of the intestine Common Curiosities What is a lumen? A lumen is a unit of luminous flux and measures the total amount of visible light emitted by a source. 14 Can you have high lumens but low lux? Yes, if light is spread over a larger area, it can result in high lumens ...
