A projection lamp can give you 500 hours, while another may give you 2000
hours before it starts to show signs of aging. So, what is it with the life
of the lamp for projectors that can assure you that the one you are buying
will have a long life? To answer, you will need to know how the lamp for
projectors works, how you can help in prolonging its life by taking just a
few precautions and, finally, from where do you buy a genuine lamp.
Your projection lamp works in one of several different ways but the
difference is not phenomenal. You have image processors that process the
information required before finally supplying the image to the lamp. The
lamp now produces an intense bright light. All the other parts of the
projector are busy with image production and the processing of video
signals. However, there are different parts that are required for your lamp
to do its work properly. These parts are the reflector and the supporting
housing besides the electrical wiring and, of course, the lamp. The
reflector collects the light from the bulb and reflects it on to an
integrator that is just a light pipe that helps in shaping of the reflected
light on to the mirrored panels.
However, your projection lamp is costly. This is because a lamp for a
projector is more complex and far more expensive. It works by igniting
mercury vapor compressed to high pressure inside a quartz tube. However,
you can extract a long life from your lamp by observing a few precautions
after reading the literature first. Do not move the projector, when hot,
because the lamp is very fragile at this time. It may even burst. Some
models of projectors have the option of the fan running even when the
projector has been switched off. Do not pull out the plug in such a case.
While changing the bulb wear a pair of gloves before handling the new bulb,
since your body oils may reduce the life of the bulb. Finally, set the
projector on the economy mode.
There are reliable distributors that stock more than 6000 bulbs of
different brands and models. When you place an order for lamp, you know
that each bulb comes with its 90 days of warranty and the clause of ‘no
questions asked’. The bulbs are all manufactured according to the OEM’s
instructions and are totally reliable. These will naturally give you long
