The model for every Projector bulbs varies for every brand and these bulbs
like other lamps and light fixtures have a limited life. When shopping for
projectors, we see a number of models with differing prices. Before taking
up a decision, one needs to find the cost of the replacement lamps and find
out what their rated lifespan. These factors give the total budget for
another 5 to 10 years. Say for instance, a $,2000 projector that needs a
new $600 lamps for every 1,000 hours will be more expensive than a $2,200
projector that needs a new $300 lamp every 3,000 hours.
The estimated life of a projector lamp is always given in hours on the
instruction manuals. This hourly ranges from 1,000 hours to 3,000 hours
which is actually an estimate and cannot be guaranteed. To reach the hours
listed for every model of a projector lamp, one should take special care
for lasting not shorter than 1,000 hours and if done properly, projector
lamps may last longer than 3,000 hours.
The lifetime rating of a projector lamps are always known before hand, it
can be replaced on time rather than the lamp burning out in the middle of a
long presentation. Today, projectors usually have built-in timers which
help to understand the remaining hours for changing the projector lamps.
For projectors that are used no more than 3 to 5 hours per day in a
dust-free environment, the lamp will last through its entire rated lamp
One should bear in mind when operating projector lamps that heat, moisture
and dust needs to be specially kept at bay. Dust causes the projector lamps
to run hotter, which means a shorter life span. Once the projector use is
done, it should not be switched off immediately instead, flip off the lamp
and allow the fan to run until it is cool. These measures should always be
taken to let the bulb cool completely with the fitted fan after every use.
The fan vents should not be blocked as the projector need to gets proper
airflow at all times.
The projector has this feature to use “Lamp Economy Mode” for lengthening
the life of the lamp by reducing its brightness. On doing so, one will get
a 50% increase in lamp life with a 20% reduction in brightness and one will
not likely get to see the reduced lumen output.
