Luminous flux is the measure of brightness of a light source in terms of the energy emitted in the form of visible light. Luminous flux, in SI units, is measured in the lumen (lm).
Depending on the application, luminous flux can be measured per lamp, fixture, per linear meter or per square meter. For lamps the most known is the luminous flux of the light bulb, in all its variants (incandescent, fluorescent, LED).
