Shop for an Overhead Projector
An overhead projector is most often used in schools for classroom presentations, but can also be used for business projects. Transparencies are placed on a flat screen and illuminated by an overhead light located in a rotating arm. This equipment is rapidly being replaced by PowerPoint presentations and computer monitors, but it is still used in many schools, police departments and small businesses.
Instructions
1. Decide how you will use the overhead projector. Perhaps it will be for school or business projects or even home use. This will determine the model best suited for your needs. If you plan on using your projector often, for class projects or business presentations, purchase a unit with an easy-to-clean, closed head lens.
2. Verify what items you will use for presentation. Consider use of color or clear transparencies or if you'll write on the material as you present it. This will determine the brightness of the lamp you'll need and the cooling system requirements.
3. Determine your budget and where to buy. Overhead projectors can cost between $100 and $400 depending on the features, while lightweight, opaque projectors can cost up to $1000. Since most schools still use overhead projectors, the widest selection is at Schooloutfitters.com, with more bargains at Amazon.com.
4. Consider the options you'll need. Direct optic projectors have a light source that is projected in a straight line to the screen, and they use Halogen lamps of up to 600 watts. Chamber optic projectors provide a sharper resolution. Due to this, they cost a bit more than direct optic projectors.
5. Purchase a sturdier housing unit if you will use the projector in a classroom with children. Portable, lightweight units are better for business travel.
6. Check for warranty and repair information. This will save time and money if a problem should arise with your overhead projector. You may want to consider a leasing option if you will need the projector on an occasional basis.
