In terms of multimedia presentations, LCD projectors have proven to provide
impressive image quality and high resolutions. However, if your projector
suddenly fails to work and you need to present a proposal with potential
clients, it could cause your business to lose money, or worse, it could
cause your job.
The most common problem of projectors is the sudden burn out of LCD
projector lamps. Fortunately, these LCD projector lamps can be easily
replaced. Although anyone can replace the lamps for your LCD projector,
choosing the lamp can be an overwhelming task. You need to ensure that the
type of lamp you buy is compatible with your projector.
A high-quality LCD projector lamp should be able to operate for over 4,000
hours. However, the measurements of lamp life are not reliable because the
lamp can still work, even if it becomes dimmer. For this reason, you need
to check the “peak lamp life” listed in most manufacturers of LCD projector
lamps, which provides users with information of the total brightness a
particular lamp could provide.
Choosing a high-quality lamp for your LCD projector should be your first
concern, instead of price. Compared to the affordable halogen lamps that
last about 70 hours, metal halide lamps can work up to 500 hours. Meaning,
the more expensive LCD projector lamp you choose, the longer-lasting life
it would provide.
How to Choose an LCD Projector Lamp
There are only two types of lamps used in LCD projectors – metal halide and
tungsten halogen. In order to choose a quality lamp, you have to understand
how each one works.
A metal-halide lamp provides better brightness, but lower consumption of
power. Be aware that lamp wattages do not reflect the brightness.
Metal-halide LCD projector lamps are more efficient because it could
provide your projector with a very white light until the end of its life.
On the other hand, tungsten-halogen lamps produce whiter lights because it
runs at a higher temperature than other lamps. Although the white light
will become yellow during its lifetime, it provides a longer lamp life
because of its low-pressure and high temperature features.
Although metal-halide LCD projector lamps are more expensive, they could
provide over 2,000 hours compared to the tungsten-halogen lamps’ 70 hours
of operation. Be aware that lamps of your projectors could last longer when
you operate them in “economy mode”, which automatically cools down when the
projector becomes idle.
