Portable Overhead Projector
If you are constantly traveling and you need something that's dependable yet lightweight, then the portable overhead projector will be ideal for all those important presentations. Yes, these projectors are easy to use and reliable. But, how does one go about choosing the right kind? Find out from the following article...

Once you have decided to purchase one, then here a couple of options to consider before you go ahead and buy it: lamp changer, hi/lo switch, open or closed head, lumen output, wide angle, standard focal length, and the singlet, doublet or triplet head. Yes, when purchasing a portable projector there is indeed a lot to consider, and if these terms all sound like gibberish to you, then it will be very easy for a slick-talking salesman to sell you the cheapest and worst equipment. Like purchasing a computer or an automobile, the more features you add, the more expensive will be your purchase. So make sure you consider the above-mentioned options carefully and how or if they will fit in with your requirements before you go ahead and make your final decision.
Features to Consider
- Lumen Output ~ The term 'lumen' refers to the amount of brightness or light that the optics of the generator and the projection lamp produces. Will your offshore presentation be in a dark room, partially dark or fully lit room? In general, boardroom or classrooms require projectors that produce roughly 3000-4000 lumens.
- Lamp Changer ~ a lamp changer is a type of projector that has two lamp sockets and lamps. You won't be burning both the lamps at the same time, the whole idea is to give you the ability to rapidly change to a completely different projection lamp during the presentation. If your presentation requires you to change a burned out projection lamp quickly, then this is a good option.
- Hi/Lo Switch ~ This switch basically controls the lumens of your projector. However, most people believe that this particular option is more or less a gimmick rather than an option.
Most people don't even need to use the warranty, and for the few who do, the warranty is only for a limited time and covers just a few components in the portable projector. So, don't let these gimmicks fool you - always purchase one that is reputed and keep in mind that there is no manufacturer who will offer any item for nothing no matter how good the warranty may sound to you.
