Lamp life buy lcd projector sony and lcd is commonly discussed in terms of " half life". this simply means the manufacture has set a limit on what they feel is the quality life of the lamp. if the lamp half life is 2000 hours, the lamp will generally last much longer although the brightness of the image may deteriorate. for example, on an lcd projector, the lamp half life is generally 2000 hours. the image brightness is normally above 85% of the original brightness up to 2000 hours. after 2000 hours you may see a drastic reduction in brightness. dlp projectors normally have less of a life and the brightness generally starts deteriorating before the half life. dlp & lcd digital sony light processing (dlp): the commercial name for this technology from texas instruments (ti): the technology inside is lcd often referred to as either "micro-mirrors", or dmd: it works this way: build a few hundred thousand tiny mirrors, and line them up in 800 rows of 600 mirrors each. now attach a hinge to each of those 480,000 mirrors. attach each of those 480,000 hinges to its own very tiny motor! power each motor with electrostatic energy!
is designed for portable use as well as fixed installation. there is an adequate handle that folds into the side of the unit and becomes almost invisible when not in use. yes, it is three pounds heavier than the, but if you need to put 2000 ansi lumens on the screen, three extra pounds is not much to complain about. activating the focus control puts an inadequate little target up in the middle of the screen, and if you don''t find the plus/minus buttons on the control panel or remote right away, it disappears. the focus control leaves something to be desired. one must toggle back and forth almost constantly just to keep the focus function active and on the screen. the target is so small that it takes several passes through the sweet spot to find the ideal setting. in future products, we would like to see a little more thought put into focusing control. produces a very bright image with sony a gorgeous color palate. the soft array of colors in was rendered as beautifully as any digital projector we''ve ever seen in this price range. the vibrant colors in were reproduced with accuracy and balance.
brightness lcd 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. you may have to reduce lighting a little, but a totally dark or dimly lit room is not necessary. 1000 - 1500 lumens aimed at large conference rooms and classrooms, these machines project a bright image even with lights on. 1500 - lumens and up these projectors are used for nightclubs, concert halls, auditoriums, churches and other large venues. with this information in mind, there are some things to consider when choosing your brightness. the light in the room no matter the brightness of your projector is, a dark room will always provide the best image. however, many situations require some light for note taking and communication. if a room''s lighting cannot be controlled, a bright projector will be needed.
