There are various types of projectors that are in use today. In certain settings, people still utilize older models, which use projector lamps that are very are to find. However, there are also other newer projectors that use different types of projector lamps. Unfortunately, there are many people who do not know the difference. It’s important to note that the type of projector that you currently own will ultimately dictate which type of projector lamp you are able to use. However, if you are thinking about purchasing a projector in the near future, one thing to think about for sure is the projector lamps and whether cheap or quality lamps are the best option for your purchase. This is the most important thing to consider when buying a projector, for the simple fact that you will eventually have to replace the projector lamp. Buying a projector that allows you to use the lamp that is easily replaceable but also lives up to your needs is the best way to go.

Comparing Projector Lamps

All of the different projector lamps have pros and cons, and one that is perfect for one person may not be for the other. For a long time, most projectors utilized halogen bulbs in their projector lamps; these have many pros. One of the biggest benefits of projector lamps that use halogen bulbs is that they are usually much less expensive than most other popular types of projector lamps. However, there are also many cons to these projector lamps. The fact of the matter is that they are cheap but also produce a cheap quality in terms of the image that is transferred. This is usually because there is a yellowish tint produced by these projector lamps that is quite undesirable. These bulbs often do not last as long as other types of projector lamps and the typical lifespan for the average projector lamp that utilizes a halogen bulb is around 100 hours.

Metal Halide Bulbs

The other available option when it comes to projector lamps – for people that do not want to use the cheap halogen bulb lamps – are projector lamps that use metal halide bulbs. The biggest con when it comes to these products is that they are typically much more expensive than the other options. However, there are many reasons that a lot of people prefer these lamps, mainly because of the quality images that these bulbs and projector lamps are able to produce. For this reason, many people have been opting for projector lamps that utilize metal halide bulbs rather than halogen bulbs. Another one of the biggest pros is the fact that there are many different options for replacing these projector lamps, as they are much easier to locate than projector lamps that still use halogen bulbs. By far, the biggest advantage to using projector lamps is the fact that they last a lot longer than all other types of projector lamps. The average lifespan for projector lamps that utilize metal halide lamps is anywhere from 1000-4000 hours, depending on the model type, brand, and amount of use.

Another thing to consider when it comes to projector lamps is whether or not you are able to use OEM lamps or compatible lamps. For those of you that are unfamiliar, OEM lamps are original lamps for your specific projector that are produced and made by the original manufacturer. These usually cost a lot more money than buying compatible projector lamps, which are made by third party companies to work for other projector types. The fact of the matter is that buying OEM lamps will allow you peace of mind, knowing you have the right lamp that is designed for your specific model of projector. However, you may be able to save a lot of money by purchasing compatible lamps from a third party company if you are able to do so.

The Connection Between Projector and Lamp

One of the best options available to people that are looking for compatible projector lamps is to try and find branded compatible lamps. These are compatible lamps that are made by a reputable and branded company. This is the best option for many people, as it will allow you to have the best of both worlds. This will give you the peace of mind of buying a lamp from a reputable company and still have the ability to save money, as compared to that of an OEM projector lamp.

The projector image looks very dim. Reason?

It indicated that you have to replace your projector lamp. In some projectors they have an inbulit option to check the hours used. Check your user guide for information about the features.

How many hours will my projector lamp work?

Just like any light bulb, projector bulbs have an expected operating time, called lamp life. 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 2000 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.

What can I do to help my projector lamp last longer?

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.

Operate your projector in a clean, relatively dust-free environment.

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’re ready to use it and avoid frequent on and offs.

Avoid shock to the lamp or projector.

Use “Lamp Economy Mode”, If your projector has this feature, to lengthen the life of the lamp by reducing its brightness. In most cases you will get a 50% increase in lamp life with a 20% reduction in brightness and you will not likely notice the reduced lumen output.

Allow the projector fan to turn off after you power down and before you unplug the projector. The only exception to this is a projector that is designed to keep the fan turning for a brief period after removing power.

Hope this answers will help you!

Below are some of the questions you have to consider before purchasing a projector lamp.

1. Compatible or original

2. Bare bulb or lamp with module

3. Is the quality of the original lamp better than that of replacement lamp?

Compatible or original

Actually it depends. It’s like choosing a branded computer and a compatible computer. Original lamps are expensive but if you’re a brand man then go for it. A compatible lamp will bring you better price performance ratio, since we still use same filament that is used on original lamp, and we just use compatible lamp cup. So we recommend compatible. They do not have big difference from the original.

Bare bulb or lamp with module

If you think the following matches your situation, you might need a new lamp with module:

a. If you do not like to install it yourself

b. You are worried you might break the lamp when you install it, since the housing is very hard to be taken apart.

c. Your lamp housing is in a bad condition.

d. Dust particles left in the Module is very hard to remove, then you need to buy lamp with module.

If you are a handy man and your projector lamp housing is still in good condition, we think buying a bare bulb is a good choice of you. Buying a bare bulb can save you big money.

Is the quality of the original lamp better than that of replacement lamp?

It’s a tricky question. When projector manufacturer chooses a lamp supplier, they not only consider quality but cost as well. If supplier A provides the best quality with expensive prices and supplier B provide very good quality but not as good as that of supplier A, but it provides better prices. Who will the projector manufacturer choose? He will choose supplier B.

Projector lamp technology grows very fast. The quality of each supplier is not very different.

If your projector is an old model, the quality of a replacement lamp is most likely better than that of original lamp.

Even for new a projector lamp, the quality of replacement lamp is very close to the quality of original one.

You never know when your projector’s lamp might fail, so it is smart to carry a back-up on business trips or keep a spare one at the presentation facility. This replacement lamp from Dell^TM is a life-saver, in case your projector’s bulb burns out. This durable bulb will give you hours of excellent, crisp and clear brightness. This product has been tested and validated on Dell systems. It is supported by Dell Technical Support when used with a Dell system.

Quality HDTV capable DLP and LCD/LCOS rear projection prices have dropped considerably in the last few years. Prices have plummeted to well under $2000 for 62 inch sizes with 1920 x 1080 super high resolution. The cost the main internal replacement lamps has recently followed suit. This is a positive development in “light” of the fact that there is a very high probability that you will have to (or want to) replace the projection lamp.

Rear Projection Televisions are not like other televisions that can run maintenance-free for 10 years or more. They need to have their lamps changed on occasion, and most have air filters that need to be cleaned every month or two. Lamps typically last about 8,000 hours on most models high end models, some of the cheaper models last only 1,000-2,000 hours. Newer LED technology based lamps last up to 20,000 hours. Keep in mind however that some lamps won’t make it all the way to their estimated life spans. If you operate your LCD or DLP TV in a warm environment that is not adequately ventilated, or at higher elevations, this can reduce lamp life. Failing to keep the air filter clean may reduce lamp life as well. And some lamps will just fail sooner than others–estimating average lamp life is not an exact science and testing methods vary greatly among manufacturers.

Considering that the average viewer spends four hours per day watching television most lamps in high-end LCD and DLP TV models should last about 5.47 years and the low end models and over 7 years for LED based lamps. However normal DLP televisions could need lamp replacement in as soon as 9 months if you watch a lot of TV. At the end of this article I provide a list of manufactures I have tested and what you can expect as far as lamp life and replacement cost.

How to Get the Most out of Your Lamp:

To extend the lamp life of your rear projection television one recommended action is to change the default color setting (and contrast) you are using to watch TV. Most rear projection televisions are delivered with their color setting on the brightest picture setting, which can reduce the estimated lamp life to less than half. The manufactures set it to the highest contrast and brightness settings because it looks best on the showroom floor of your local electronics store.

Most rear projection televisions come with three presets. For example, the Sony’s LCD rear projection TVs has three presets Vivid, Standard and Pro. Vivid is the preset the KDS-R60XBR1 is set to when first taking it out of the box. The “Vivid” setting will lessen the life of the lamp to approximately 3600 hours because it is the brightest setting. The “Standard” setting will extend to about 5300 hours of lamp life and “Pro” will further extend the lamp life to around 8000 hours. No matter what rear projection TV you own, changing the picture setting to normal or standard will lengthen the life of the lamp. Decreasing the contrast setting to around 50% will accomplish the same.

Here is a checklist of what to do to get the most out of your lamp:

1. Check out the presets and select the setting with the lowest light output.

2. Once you’ve done that adjust the brightness down to your liking. The lower the brightness the long the lamp will last.

3. Check and clean the air filters on a monthly basis. Having a clean air filters means that your lamp has better airflow. Air is what is used to cool the lamp and the cooler your lamp runs the longer it will last.

Warranties and Lamp Replacement:

The manufacturer warranty typically covers the replacement of a lamp if it goes out during the manufacturers standard warranty period, but many only cover the first 90 days of the lamp life. Check your owners’ manual for the specific coverage offered with your TV.

When purchasing an extended warranty on your projection TV be sure to check if it includes lamp replacement in the projection TV during the extended warranty period. Verbal confirmation is not good enough. See it in writing. In many cases there is an additional charge specifically for a replacement lamp warranty though some extended warranties such as the XpresServ warranty do cover bulb replacement.

From our past experience with DLP rear projection TVs over the past several years and all the problems these TVs have encountered repair wise, we definitely recommend purchase of an extended warranty if you can find a reasonable price that includes bulb replacement. Rear Projection TVs need more frequent service than other types of TVs even though the repairs are usually fairly easy. They require a lot of professinal tweaking. For this reason, try to purchase an extended warranty with in home service. If you are in the average among TV watchers, you will likely need to have the lamp replaced within the first 2 to 3 years. A five year extended warranty covering defects and in home repair service usually cost around 10% of your TV.

Replacing a Lamp After the Warranty:

To find a lamp for your television I recommend going back to the company you purchased your TV from or you can usually find good prices at the dealers listed on this site.

If you need to replace the lamp after the warranty period you have two options you can either do it yourself or hire someone to come out a do it for you. Replacing the lamp yourself can seem like a daunting task but it’s usually not that difficult and can be done in less than an hour, with the actual replacement only taking a few minutes.

Each owner’s manual for a rear projection TV comes with instructions on how to replace the lamp. Here are the typical steps for replacing a lamp.

1. Turn your TV off. Let it sit there for about 5 minutes to let the cooling fan help cool the lamp.

2. Unplug your TV from the power let it sit about another 30 minutes. Even with the TV turned off power is still going to the lamp and the lamp receptacle can still be hot enough to burn you. Even if you think that the lamp is cool I recommend that you do not touch the receptacle.

3. Usually the lamp has a cover that you will need to unscrew. Most manufactures use a Philips head screw for holding the cover shut. Unscrew the lamp cover.

4. Unpackage the replacement lamp. Be careful not to tough the glass, as oil from your fingers can damage the lamp’s surface.

5. Pull the lamp out. Most lamps have a plastic tab or hoop on the handle that you can use to pull it out. Follow the owners manual for specific instructions on how to pull the lamp out. Make sure you do not touch the surrounding lamp housing if you just turned off the TV. It can burn you if it is hot.

6. After the lamp has cooled, place it into the empty box of the replacement lamp. Never put the used lamp into a plastic bag.

7. Using the guiding post also called “gutters” by some manufactures slide the lamp replacement lamp in pushing it until you hear a firm click.

8. Screw the lamp cover back in.

Managing the Used Lamp

Do not leave the used lamp near flammable materials or within the reach of children.

Do not pour water onto the used lamp or put any objects inside the lamp. Doing so could cause the lamp to burst.

1. Have your equipment powered down before connecting any cables. A signal cable carries a current while powered on and a sudden difference in electrical current can potentially burn out the projector lamp or cause other damage to projector components.

2. Use economy mode whenever possible. If your using a projector that has over 2000 lumens (a term used to describe the brightness of the projector), it usually has some sort of economy mode. If the event does not require full projector brightness use this mode to extend lamp life. Economy mode will lower the amount of lumens to save power and lengthen lamp life.

3. Avoid moving the projector as much as possible while it is powered on. The lamp, along with various other projector components, are sensitive to shakes or bumps. Any significant trauma could damage the projector and or lamp.

4. Do not unplug the projector after powering down. The cooling fan will continue to run in order to cool the lamp after shutting down the projector. It is recommended to keep it plugged in for at least another 3 minutes, doing otherwise could shorten the lamp’s life or even damage the lamp.

5. Clean your projector. Dust is the bane of projectors when allowed to collect in the filter or on the lens. A microfiber cloth works well for cleaning the lens. If dust collects on the filter it will block the filter and decrease air flow which can affect the projector’s cooling and can shorten lamp life.

You will have noticed in these tips that we pay special attention to preserving the life of the lamp. The reason for this is because the lamp is the most crucial part of the projector, and as such, is the most expensive component to replace. Projector costs have gone down significantly in the past few years, but replacement lamps have not. Lamps can cost up to $400 so you can see why it might be important to conserve as much lamp life as possible.

1. Wear gloves when you handle lamp. There chances of getting hot spot because of oils and other deposits from hands and fingers. Handle carefully.
2. Always keep projector air filters clean. If it’s not clean then it will not vent heat properly. This may cause damage to the projector due to over heat. Also make sure that you are not keeping anything in front of your exhaust vent. This will also cause over heat.
3. Close your lamp housing properly. If its not sealed properly then there are chances of getting dust.
4. Do not move your projector when your lamp is too hot. Hot lamps are very fragile. Small vibration may affect the lamp filament to break. So move when it’s completely cooled.
5. Do not unplug the projector until the lamp has properly cooled. After the projector has been shut off, the fan will remain on for about 5 minutes. This aids in cooling the lamp evenly and completely and decreases the chance of early lamp failure.
6. Do not turn the projector on and off habitually during presentations. Each time the projector is switched on, the supply of power causes stress on the lamp filament. Try to minimize on/ off cycles.
7. Some projectors offer “low lamp” or “economy mode” options. Use them whenever possible. These options have been developed to extend lamp life.
