BRIGHTNESSBrightness is becoming less important as projectors get more advanced.The brightness of a projector is measured in lumens. Most projectors released in the last year are around 1500 lumens or above, which is more than adequate for the average board room seating about 20 people. Brightness is much less important for home cinema or you may opt to go for something between 2000 and 3000 lumens. However, expect to pay a bit more for this luxury!
