• Source: Orders of magnitude (illuminance)

As visual perception varies logarithmically, it is helpful to have an appreciation of both illuminance and luminance by orders of magnitude.




Illuminance


To help compare different orders of magnitude, the following list describes various source in lux, which is a lumen per square metre.




Luminance


This section lists examples of luminances, measured in candelas per square metre and grouped by order of magnitude.
