Decades ago, projectors were so bulky and expensive that only businesses and organisations had them. As a projector is able to project images onto a large screen or surface, it is usually used for presentations to large groups of people. But these days, they are a lot more affordable and portable, so it’s not uncommon for families to have one at home.


Images are magnified onto a large surface or screen using a bright light bulb and lens. How big the projected image is depends on the resolution, brightness of the bulb and the distance of the projector to the screen. Usually mounted from the ceiling, at home, it may be used to watch movies or live sports when there’s a large gathering. Some home users are even doing away with the TV set, in favour of this device. 


There are three main features one should look out for in projectors: resolution, bulb brightness and bulb longevity. In summary, the higher the resolution, the sharper the image.

Bulb brightness is measured in lumens. If you’re using the projector during the day, you would need a brighter bulb. If the viewing environment is dark, most portable projectors with lower lumen ratings would be sufficient.

Bulb longevity is measured in “bulb hours”. A good bulb should last between 10,000 and 20,000 hours before it needs replacing. If you aim to project onto a large screen, go for a projector with a high resolution and a very bright bulb.
