How to Set Up a Projection-Based Home Theater, Step by Step Lumen is a measure of amount of light emitted by the projector; in layman’s terms, the brightness. A low lumen value – 1500 or less – will only be visible in a dark room. 3000 lumen and higher will be visible in daylight, but truthfully any projected image will look better when there’s less ambient light.

How LCD Projectors Work The old method of film projection was simple: Each frame of the film was a tiny, translucent photograph. Shine light through the film and then have that light pass through an imaging lens and you'd display a larger version of that tiny image onto a wall or screen. LCD projectors work a little differently. A beam of high-intensity light travels through thousands of shifting pixels in an LCD display instead of through a frame of translucent film. And these projectors don't just use a single LCD display either -- they use three, which is why they're also called 3LCD projectors.
