Overhead Projector Lamps – These projectors lamps feature an intense light bulb and a flat base beneath it. This projector bulb sends the image to a special type of mirror, which in turn enlarges the image and delivers it to the blank screen. High-power halogen lamps are generally used in an overhead projector lamp. Business professionals or educators who want to share graphs, sales charts, and other documents will find an overhead projector lamp extremely useful. They are also the most affordable of the lot.
Slide Projector Lamps – These bulbs are especially useful for viewing photographic slides. Projector lamps in a slide projector contain a unique slot for 35 millimeter slides. The images present on each slide are enlarged and then projected on the big screen. Slide projectors are ideal for teachers, professionals, or photographers who demonstrate using physical camera images.
Multimedia Projector Lamps – Images from DVD, film reel, or videotape are enlarged projected on a larger screen by these lamps. Movie theaters and home theater systems make use of a multimedia projector. Though the most expensive among the three, lamps in a multimedia projector last approximately 2,000 hours or more.
