The use of multimedia is the expected norm in business presentations to support meetings and gatherings. The business and education sectors thoroughly depend on having video projects available for use at the drop of a hat. Any businessman that does not involve multimedia in making product promotion presentations is missing out on a powerful tool, and perhaps may not be taken seriously by your customers. The razzle-dazzle of a slick PowerPoint presentation is almost an expected part of certain promotional methods. It isn’t just limited to the corporate world. Groups from religious institutions, schools and clubs also are heavily into this technology.
The technology that permits these kinds of presentation, namely video projectors, are in fact very reliable devices, but all of them depend on projector lamps to furnish the illumination at high intensity. These lamps have a finite lifetime, since they operate at high intensity and high temperatures. They typically last from 1500 to 3000 hours. Now, if you do 2 hours of presentations each day, which is moderate use, the lamp should last for about 4 to 5 years of M-F use. Naturally, if it is used for six hours a day the hours add up and the lamp might quit after one year. When these projector bulbs reach their end of life, you will have no warning. If you don’t have a spare lamp, you may be unable to do presentations for several days until you locate a replacement bulb. However, by planning ahead, you can have a spare bulb for your projector handy. It might even be wise to go through some of the actual motions of replacement so that when you really have to replace the lamp you will not experience much downtime. Read the rest of this entry »
