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.
