Getting a bright projector makes more sense if you’re buying it for presentation purpose than home theater purpose. For the former, you especially need sufficient light output to counter the ambient lighting, so that the screen doesn't get all washed out. For the latter, there's always this implicit assumption that you're able to control the room lighting. That said, brightness is an essential spec to pay attention to when buying a 3D projector. Since each eye only picks up half the light from the screen, the projector's brightness is effectively halved in 3D mode.
Another spec to look out for is contrast ratio - this basically means the number of levels between the blackest black and the whitest white a projector can achieve. But no matter how high your projector’s contrast ratio is, it’d be wasted if you can’t control the room lighting. The quickest and easiest way to improve contrast even if you’ve a beamer with a low contrast ratio is to turn down the lights, though many a time this isn’t possible. Also, avoid projecting on a wall or a blackboard; use a projection screen instead.
