OHP accessories
Overhead projectorsSingle and triple lenses

Standard single element lens overhead projectors are fine for writing on acetate sheets or displaying text on screen. High definition overhead projectors have a triple element lens that is designed for displaying fine pictures or engineering diagrams. These are more slightly more expensive than standard overhead projectors.

Single and twin lamp projectors

Overhead projector lamps are inexpensive but only last around 50 hours. When a lamp blows it will need replacing. You need to let the projector cool down before doing this. If the lamp dies during a presentation or teaching session this would be inconvenient and disruptive. Twin lamp overhead projectors have two lamps installed with only one lamp being used at a time. If one lamp dies then a switch is thrown to turn on the second lamp.

Projector brightness

Projector brightness is measured in ANSI lumens. Standard overhead projectors are around 2200 ANSI lumens (250 watt) and are fine for normal classrooms. High brightness projectors are around 4200 ANSI lumens (400 watt) and are used in lecture theatres and other very large rooms.

Flatbed and portable projectors

Flatbed overhead projectors are designed to be portable so that the projector can easily be carried between venues. These are around 5kg to 7kg in weight and fold for easy transport. Some standard projectors just have a foldable arm to allow easier transport.
