Projector Lamp Advice For UK Consumers

Increasing The Amount Of Time Your Projector Lamp Module Lasts For
Increasing the number of hours that a projector or television lamp lasts for is often a major concern for people who own projector or DLP TV equipment. The following Projector Lamp Experts UK information section will provide you with some helpful advice about the length of operating time that you can expect from your projector's lamp module, and furthermore the measures that you can take to try to get the maximum amount of life time possible from your LCD or DLP projector or rear projection DLP television lamp.
How long does a projector lamp operate for?
A projector lamp's life, or operating time, is an important concern for projector users, since most people will need to replace their projector or TV's lamp at least once over the unit's life. Each projector lamp made has an expected number of hours that it should last for. This is often referred to as the "lamp life", and is normally quoted in a number of hours. For an average projector lamp, the lamp will normally last in the range of 1,500 to 2,000 hours. Some projector models which were made more recently boast lamps which possess an expected lamp life of more than 5,000 hours.
The quoted figure for projector lamp life is based on a bell curve average. This means that the majority of projector and TV lamps will last for the 1,500 to 2,000 lamp hours quoted, but there will be the occasional projector lamp which might not last for this expected number of hours. Most, if not all projector lamp manufacturers will supply a warranty with their projector lamps which will protect the consumer from early lamp failure for a certain period of operating time or number of operating hours.
The life of the lamp inside a projector or television is affected by the conditions it is used in. A lamp will have the best possibility of lasting for the expected 1,500-2,000 lamp life hours if it is operated under normal conditions. This is defined as using the projector for approximately three to five hours of per day in a clean operating environment which is as free as possible from dust particles. If the lamp is inside a projector or TV which is used in an environment containing lots of dust, or if the projector equipment is used much more frequently than three to five hours per day, it is more likely that the projector or TV lamp will last for a fewer number of hours. If the projector or TV lamp is inside equipment that is constantly on, for 24 hours a day, 7 days a week, this lamp would be at the highest risk of burning out early before the quoted lamp life hour expectancy.
When should a projector lamp be replaced?
During the operation of your projector or television, as the metal halide lamp inside gradually loses power and pressure builds up inside the projector bulb, you will be able to see a gradual reduction in the brightness of the projected image. Although this gradual dimming can be hard to detect at first, it will eventually have a noticeable effect on your projector or TV's display. When you start to notice your projector or TV display dimming, it is time to replace your equipment's lamp. Occasionally a projector or TV lamp may burn out completely at end of its life which is usually caused by temperature stresses on the bulb itself. Most projectors which were made recently have a counter built into the projector which counts the number of hours the lamp has been operating for, and will alert you when it is time to change the projector's lamp. After each time the projector lamp is replaced, this lamp hour counter should be restarted. Your projector's user manual will have more details on the lamp hour counter feature if one is available. If you cannot find the lamp hour counter on your projector, you can contact Projector Lamp Experts UK for assistance. We will be happy to help you.
How can you make a television lamp or projector lamp last longer?
The list below describes some of the steps that you as a projector operator can take to make sure that the lamp in your equipment lasts for the maximum amount of time possible.
- Leaving your projector in an extremely hot or a very cold environment should be avoided at all costs, for example in a car on a summer or winter day. The main cause of early projector lamp failure is exposure to excessive temperature stresses.
- Try to make sure that your projector or television does not overheat while it is in operation.
- You should try to make sure that there is a good amount of space around the projector or TV's fan or exhaust system so that extra heat produced by the projector or television can be dispersed away from the unit effectively.
- If it is suitable for your situation, and the option is available on your projector, try using the economy projector mode, which reduces the brightness of the light that the lamp outputs but increases that amount of time that the projector lamp will last for.
- Always try to let your projector's lamp cool down after you are finished using it, for at least 10 minutes before you unplug your projector. You should also try to steer clear of moving the projector equipment during this cooling period and while the projector lamp is powered up. Damage to the projector lamp is much more likely while the lamp is very hot.
- If you can operate your projector or DLP TV in a clean environment which does not contain much dust, your lamp will stand more chance of lasting longer. A reduction in dust around the projector or TV will stop the projector or TV's cooling fans and air filters from becoming clogged.
- The air filters on your projector or DLP TV should be cleaned regularly and often.
