Brightness - Measured in ANSI Lumens
It is important to consider the brightness of the room environment. No matter how powerful your projector, you generally can't compete with the sun unless you are prepared to spend a small fortune. When thinking about where to put your projector and screen, consider where sunlight comes into the building and see if you can put blinds up if necessary.
