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 life.

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.
