It is vital to get a model which produces the highest quality since projectors are used mainly for presentations. The projection of images of these devices depends on three aspects such as the brightness, type of lamp used and the projection surface.
If the brightness of your projector is not sufficient, it will tend to blur the images. The brightness is measured in terms of ANSI lumens. For ultra light projectors, the most ideal is around 1,000 lumens while for larger rooms like conference halls should at least be 4,000 lumens. Fixed installation projectors should be 10,000 lumens.
The most ideal surfaces are to use screens rather than walls. Screens produce better quality images. The best background for screens is either white or gray.
The lamp type is the main factor in producing brightness. The most commonly used lamps are the Ultra High Efficiency (UHE) and the Ultra High Performance (UHP). It is common for the lamps to die around 1,000 to 4,000 hours of usage.
It is best to choose lamps with lower wattage since they are more economical and will last longer. Some of the projectors come with an economy mode feature which greatly helps in prolonging the lifespan of the lamp.
