If you are going to watch a movie during daylight hours, the best projector is the one with the highest lumens output and the highest resolution. Thus, instead of going for a projector with hundreds of lumens, you should choose one with thousands.
1000 lumens is usually enough in a dark room. A lot more light is needed in brighter rooms and outdoors. Choose a lamp with a lumen rating of 2500 or more. If the room is bright and large, you should use a projector with at least 4,000 lumens.
Pay attention to the lumens listed on your projector when you want to project outdoors, such as videos or music. Choose the brightest possible lumens for outdoor viewing during daylight. The screen will likely need a projector with a brightness of 5,500 lumens if it is more than 40 feet across.
