Projectors While LCD systems with less than 400-500 ANSI lumens may be sufficient for projecting black and white Excel images in dark room settings, they may not have enough firepower to keep multicolored PowerPoint presentations from appearing washed out. When deciding
how much brightness your projector has to have, keep in mind how
dark the rooms will typically be for your presentations and how
far your projector will be from the screen. The more light in the
room or the farther away the projector, the brighter your projector
should be. ANSI lumens for projectors currently range from 400 to 1,000 for ultralights up to as much as 10,000 for fixed machines. For on-the-road presentations, 500 to 1,000 ANSI lumens should be fine. Larger conference rooms will need 1,000 to 2,000 lumens, while fixed installation machines will need to project between 2,500 and 10,000 lumens to handle auditoriums or other large venues. The brightness of a projector can sometimes be misrepresented, so be sure to check the brightness of the individual projector and not the published brightness of the model line. Lamp Type If you're comparing two projectors of the same brightness, ask about the wattage of their respective lamps. If there's a difference, go with the projector that has a lower-powered bulb. The low-watt lamp will last longer, stay cooler, and be more efficient than a bulb with a higher wattage. |
