The total luminous power of a light source.
The light flux is measured in lumens (lm) and describes the total amount of light produced by a light source.
Diffusing decreases the density of the light flux as you move away from the source.
Luminaires with the same capacity can produce different light fluxes depending on their light efficiency.
At Ledee, we do lighting calculations using DiaLux to estimate the amount of lighting needed and its distribution.
