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.
The amount of brightness you need is determined by the room you project in. Projector brightness is measured in lumens. For home theater projectors where ambient light is kept to a minimum, you'll need a minimum of 1500 lumens.For classrooms, conference rooms or rooms with windows, a projector with a minimum of 2500 lumens is best.For large auditoriums or lecture halls, you'll need more lumens.f you are looking to buy a new projector for a classroom, meeting room or home theater, the image you project on the screen should make a great impression on your audience.
