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.
Keep in mind that when comparing lumens you are dealing with ratios. For example, an 3000 lumen projector will look 50% brighter than a 1500 lumen projector. A 5000 lumen projector will only look 30% brighter than a 3500 lumen projector, even though there is a difference of 1500 lumens in both cases.ontrast Ratio works hand in hand with lumens. A projector with a 1000:1 contrast ratio will look brighter than one with 400:1, even though they have the same lumen rating. This is particularly true in a darkened room.
