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.
Lumens are a unit of measurement of the total brightness that comes from a light source, in this case, a projector. One may also see the term ANSI Lumens. ANSI is an acronym for the American National Standards Institute. In general, the more lumens a projector has, the brighter the image on the screen.sually, the brighter the image, the sharper the contrast will be. Lumens are extremely important due to the fact that projectors with lower Lumens require ambient lighting to be low. In addition, less lumens generally means that the projector will need to be closer to the screen.
