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.
Most Home Theater Projectors have Lumens Ratings that average between 1000-1300 Lumens. Home Theater Projectors are typically used in a darker, light-controlled setting, therefore less lumens is required. In the board room, a Projector might have a Lumens Rating between 2000-3000 Lumens.or example, a 100 watt light bulb produces roughly 1200 Lumens. In this case, we are referencing the amount of light produced by a projector or the projector lamp inside the projector.
