The 3M Model 1865 Overhead Projector features 3,400 to 4,000 lumens of light for bright, big-screen images. A unique color-tuning dial eliminates blue or brown corners, two different lamp settings switch between high and low for crisp black-and-white text and vivid color images, hushquiet fan reduces noise for more enjoyable presentations, and convenient carrying handle and fold-down post adds optimal portability and storability.
Features also include thermal-protection circuit that disconnects power to lamp in the unlikely event that the projector overheats, practical lamp ejector that makes replacing lamps simple, lamp interrupt switch that shuts off power to lamp, when changing lamps, to prevent premature lamp failure, and handy power-cord wrap.
