You''ll even have some extra space in your briefcase. 1,000 LUMENS. The remarkable thing about the LP 130 is you give up very little to gain ultra-portability. The projector is based on the Instruments digital light processing system and puts out a very impressive 1,000 lumens. In plain English, that means it projects an image bright enough to be seen comfortably in a normally lit conference room. It can handle resolutions up to 1,024 x 768 pixels and features a zoom lens, which allows you to control the image size from a fixed projector location.

In the projector business, small and light still translate into expensive. One cautionary note about any projector: Always allow the unit to cool completely before packing it up, and treat it at least as gently as you would a laptop. specifies the lamp life as 2,000 hours of use, but that can be shortened

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 in this range are geared toward normal business conference room and classroom use.

Over $8,000.00 These are usually projectors with either XGA(1024 x 768) or SXGA (1280 x1024) native or true resolution incorporating a minimum of 1,000 lumens of brightness Projector warranties vary from brand to brand. However, they usually have at least one year or more coverage of all parts except the lamp. The lamp will sometimes have a 90 day warranty. Some manufacturers also offer a 24 hour replacement service. In some cases, this may cost extra. Contrast Ratio is the ratio between the whitest and blackest portions of an image.
