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.
They are definitely the least bright projectors almost all with less than 100 lumens. They are limited in use, need a really dark room to do a good job on a small screen â say 40 inches, but are the ultimate in portability. Pocket projectors are the next size up, and like Pico Projectors tend to have LED light sources. These weigh from roughly 1 lb. to about 4 pounds and are mostly 300 â 700 lumens with the brightest hitting 1000 lumens (2015). These are becoming more and more practical each year.
