we''ve created even greater values for customers in the projector marketplace." The heart of these projectors'' advanced imaging technology lies in own three-LCD projection system. These three 0.7-inch LCDs are engineered and synchronized to achieve high levels of image quality, such as brightness distribution (illumination ratio), color saturation, color accuracy and efficiency. They create varying shades of red, green and blue that blend to produce a projected image with brighter, richer, truer colors and sharp black text. Barely two years ago, I hailed a projector that weighed in at under seven pounds. At the time, that seemed like a great breakthrough for weary road warriors. It meant that together with a laptop weighing six pounds or so, a mobile exec could have a complete presentation kit small enough to fit into an oversize briefcase and light enough to carry without risking grave damage to the back. Funny how these things evolve: By today''s standards, that setup is a big, bulky dinosaur. Brightness is measured in lumens. The lumens can range anywhere from 300 lumens to 3300 lumens, with 3300 being the brightest. Lumen Range Comments 300 - 500 lumens These will usually be the least expensive projectors. Also, the low light output may require your presentations to be made in a dark or dimly lit room. 500 - 1000 lumens Projectors projectorsdealer and projectorsdealer in this range are geared toward normal business conference room and classroom use.
