subject: Things To Consider When Selecting An Overhead Projector [print this page] From classroom sessions to business conferences, projectors are widely used for presentations. Even though using a digital overhead projector is easier than other projectors, choosing a particular overhead projector is a tough task. Its even more difficult if you are buying a digital overhead projector for the first time. This blog post will help you make an informed buying decision.
The most important thing to do is to opt for an overhead projector from a reputed brand. When you buy a digital overhead projector from a world-class company youll get two benefits. The first advantage is that a product from a reputed brand offers reliable performance. Secondly, most of the leading companies provide excellent after-sale service to their customers.
If you are buying an overhead projector for your office conference room or college seminar hall, a stationary overhead projector is the one for you. On the other hand, if you want to use your digital overhead projector in different places, a portable overhead projector would be the right choice. You can carry a portable projector in a bag or suitcase comfortably.
Brightness, also known as lumen output of the overhead projector bulbs or overhead projector lamps, is another important aspect to be noted while purchasing a digital overhead projector. If you are going to use the projector in a dark room, then overhead projector bulbs with a higher amount of lumen output are required. But, if youll be using the overhead projector in a bright environment, lower intensity overhead projector lamps will do the job.
The basic structure of an overhead projector is called head assembly. There are singlet, doublet, and triplet head assemblies. Choose them according to the distance you need to project your images.
When it comes to open head or closed head overhead projectors, ,its better to choose a closed head overhead projector, as it is safer than an open head projector. This is because open head overhead projectors are more prone to physical damages than closed head overhead projectors.
