This value is expressed in hours and represents the number of hours before the lamp is at half its original brightness. The expected life of a lamp will vary based on the lamp technology and the projector; however, most projectors offer about hours. The lamp's success rate is based on a bell curve, so that a majority of but not all lamps will meet the lamp life hours specified.
Some lamps will fail sooner and this is part of the acceptable operating range of the rating. For projectors that are used under normal operating conditions no more than three to five hours per day in a clean, relatively dust-free environment the lamp will have the greatest likelihood of lasting through its entire rated lamp life.
There are several things you can do to increase your lamp life. Do not allow the projector to become overheated by ensuring that there is adequate clearance near the intake and exhaust vents. Clean air filters every 3 months or more often if there is a lot of dust or contaminants in the room.
Striking the lamp ages the lamp as it causes slight changes to the shape of the electrodes that light the lamp, so light up your projector when you are ready to use it and avoid frequent on and offs. If your projector has this feature, use 'Lamp Economy Mode' to lengthen the life of the lamp by reducing its brightness.
Allow the projector fan to turn off after you power down and before you unplug the projector. Projectors that are used more often or are exposed to environmental contaminants are more likely to show a decrease in lamp life. Projectors that are operated 24 hours a day, 7 days a week are at the highest likelihood of lamp failure before the end of the rated hours. Metal halide high pressure mercury projector lamps experience a gradual dimming of the image brightness as the lamp loses power and pressure builds up within the bulb.
The dimming may be subtle but will nonetheless have increasing impact on your display. You should replace your lamp when the dimming of your image becomes noticeable. Occasionally, at the end of its life the lamp may fail altogether, usually due to temperature stresses. Most modern projectors have a built-in lamp hour counter which will let you know when it is time to change your lamp, and this counter should be reset every time the lamp is changed. Check your projector's user guide for information about this feature.
If you are unable to find the lamp hour counter simply contact one of our Lamp Experts who will be happy to assist you. The following is a list of preventative measures you can take to reduce the likelihood of your projector lamp failing early:. Toll-free phone : Email: info projectorlampexperts. This will give you access to the remaining lamp hours or the lamp hours used so far by your projector lamp.
Knowing how to check lamp hours will vary from one model of the projector to another. Your email address will not be published. Save my name, email, and website in this browser for the next time I comment. Skip to content How long should a projector last? What Is a Projector Lamp?
How Does a Projector Bulb Work? Standard Projector Lamp: A standard projector lamp has an ARC or metal halide lamp with ultra-high-pressure mercury vapor within the bulb. Projector lamp lifespan for this lamp type ranges from 1, hours, 1, hours 2,, hours, and 5, hours. LED Projector Lamp: There are also lamps that make use of LED light-emitting diode bulb technology that lasts significantly longer than their standard metal halide counterparts.
The projector lamp lifespan for this lamp type can be as high as 60, hours or 30 years because it has a 30,hour half-life, which is the case with LED technology. Laser Projector Lamp: A laser or LASER light amplification by stimulated emission of electromagnetic radiation projector lamp has a 20,hour lifespan. What Is Half-Life? It also refers to the time required for a quantity to reduce to half of its initial value.
So the half-life of a standard lamp with a lifespan of 1, hours is about hours. In turn, LED lamps take about 30, hours before it becomes half as bright as before because they have a 60,hour lifespan Projector Lamps and Brightness The brighter the projector lamp the easier it is to burn up. The Bell Curve and Warranties: Most if not all lamps will meet the lamp life hours specified on a given type of light bulb barring things like accidental drops and whatnot because the light output of these lamps are based on a bell curve or the likeliest lifespan scenario.
Many manufacturers entice people to buy their specific projectors by having a warranty covering lamps for a certain period of time or number of hours.
If the lamp fails before 1, or 5, hours but not through customer-induced damage CID , you get a replacement lamp free of charge. When to replace a projector lamp? Your projector lamp could last for only months or up to 7 months if you have it running 24 hours a day and 7 days a week doing Simpsons marathons or something. However, normal operating conditions of hours a day in a clean, dust-free environment will allow you to use these months for years.
Factors such as Environmental Contaminants and Abuse: Your light bulb is covered for a reason. Dust and other environmental contaminants like pet dander and even insects can gather around a light bulb, cake themselves on it, and make it overheat faster, resulting in its quicker destruction versus the bell curve average of 1, hours or 5, hours.
