What Does Lumens mean. The technical definition of lumen is as follows; A lumen is the standard measurement for a unit of luminous flux, it is a measure of the perceived power of light.hat's because watts and lumens measure two very different things. A watt is a unit of electrical energy in other words, input. A lumen is a measure of light intensity output. More simply a light bulb uses watts to make lumens.
Lumen (unit) - Explanation. 1  If a light source emits one candela of luminous intensity uniformly across a solid angle of one steradian, the total luminous flux emitted into that angle is one lumen (1 cdÂ·1 sr = 1 lm). Alternatively, an isotropic one-candela light-source emits a total luminous flux of exactly 4Ï lumens.
