​One of the trickiest aspects of creating lighting plans can be working out how much light is enough.

It comes down to being able to quantify ​light, which we achieve through knowing the lumen output of a fitting (Lumens is a measure of luminous flux, which is how much light is emitted by the light source/fitting) and the mounting height at which it will be installed and then being able to understand the quality of that light for performing various tasks in the home.
