Make your projector lamp last: Don´t move your projector While the projector lamp is still on (even while it is powering down), the lamp is very sensitive to movement. Moving the projector while the projector lamp is still on could shorten the lamp life, or worse, it could cause the projector lamp to burst. Projector lamps: Changing the projector lamp For most projectors, installing a projector lamp is simple and usually only involves the turning of a few screws. However, keep in mind that the projector lamp housing and glass are very fragile, so you should consult your owners' manual or the instructions that came with the projector lamp, before you attempt to install the lamp yourself. The most important precaution to note is when handling the projector lamp, NEVER touch the glass housing on the lamp. Oils from your fingers can cause the projector bulb to burn out or even burst prematurely. Handle the projector bulb carefully using the metal housing, and your lamp should last thousands of hours. Make your projector lamp last: Give your projector "breathing room" Make your projector lamp last: Give your projector “breathing room”. Pay attention to where the fan exhaust is on your DLP or LCD projector. All of the heat from the projector lamp must be dispersed away from the projector and exits at the fan exhaust. Make sure that this projector fan exhaust is two to three feet away from a wall or any solid object that could block it. Without “breathing” properly, the projector lamp will be too hot and could burn out much sooner. Make your DLP or LCD projector lamp last as long as possible by using this projector lamp tip. Projectors for less: SVGA Resolution Projectors SVGA resolution projectors will save you several hundred dollars over XGA resolution projectors. If you will be projecting small to medium sized type, or very detailed images, SVGA resolution projectors may not be for you. However, if the majority of your projector presentations will be PowerPoint presentations with large text and images, SVGA resolution may work, and will save you plenty over a comparable XGA resolution projector. Projector lamps: What does a projector lamp cost? If you think the cost of a projector lamp is comparable to a standard 60-watt lightbulb, think again. Projector lamps are relatively expensive, ranging from $200 for low lumen projectors, to over $600 for high lumen projectors. The average projector lamp cost is $350. There are good reasons that the price is what it is. Projector lamps are highly sophisticated instruments that produce amazing brightness. In addition, the assembly process is complicated and supply is somewhat limited. Some projector bulbs are on backorder for several months! We recommend purchasing a spare projector bulb when you buy a projector. That way, you will have a spare in case of emergencies, and you might also get a good discount on the lamp by purchasing the projector as well. Make your projector lamp last: Avoid hazardous climates The most hazardous climate to a projector lamp is extreme cold in the wintertime. If you leave a data/video projector in your car when it's 40 degrees or below, the data/video projector lamp will have a tendency to explode if you turn the projector on immediately. You must allow the data/video projector to warm to room temperature before turning on the projector to avoid the dangerous scenario of an exploding projector lamp. Projector lamps: Projector Lamp Warranty Projector lamp warranties can vary between manufacturers so consult your users' manual or manufacturer's warranty information. If you no longer have a users' manual, consult with an online projector purveyor and they may be able to furnish you with the information. The typical projector lamp warranty is 60 or 90 days from receipt of projector. Projector troubleshooting: Projector image is cut-off The solution to this common problem is simple. This usually occurs when your multimedia projector's resolution is in sync with the computer resolution. This is typically a simple fix that can be solved by pressing the Auto Image or Image Sync button on the multimedia projector or remote. This should automatically resize your projected image to match your computer resolution. If this does not work, or if your multimedia projector does not feature this intuitive Auto Image button, you'll need to change the resolution on your computer. Projectors are typically SVGA resolution (800 x 600) or XGA resolution (1024 x 768). Change the resolution on your computer to match the projector resolution. Consult your computer manual on how to change your computer resolution. Make your projector lamp last: Don´t leave in hot car This projector lamp tip should go without saying. Most any electronics can be damaged when left in a car on a hot summer day. Without air conditioning, a car can reach temperatures hot enough to fry an egg – or a projector. Take heed of this projector lamp tip and make sure that your projector is always in a room temperature environment. Make your projector lamp last: Allow projector lamp to cool What is the most common reason for projector bulbs with shortened lives? Not allowing the projector bulbs to cool. Most projectors have a feature where they power down themselves, just make sure that you don't move the projector while it is in this mode. Some older model projectors may also feature a hard on/off switch as well as a projector lamp on/off switch. For those, turn the projector lamp off first and after it powers down, turn the projector off. Make your projector lamp last: Use projector in Eco-mode Many digital projectors offer what is called Economy Mode or Eco-Mode. This is a setting that uses less brightness from the projector lamp, yet will make the projector lamp last longer. An example of this projector Eco-Mode is if you have a projector with 2000 lumens of brightness, its lamp hour rating might be 2000 hours. If you put the projector in Economy Mode, the brightness might go down to around 1600 lumens of brightness, but the projector lamp may last 3000 hours. If you go back and forth from the two brightness options, then your lamp hours would be somewhere between 2000 and 3000. Make your projector lamp last: Don´t shake your projector Be careful not to shake, jostle, bump or move your multimedia projector quickly, especially when the projector is on. A multimedia projector's electronics are sensitive to these types of movements. Projector Lamps: Projector Lamp Life Expectancy For older model projector (prior to year 2000), most projector lamps last approximately one thousand hours. Today´s newer multimedia projectors feature projector lamps that will last for two thousand hours or more. A few multimedia projectors will produce up to four thousand hours of use, and a handful will boast an astonishing six thousand hours of projector lamp use. Many multimedia projectors now offer two different lamp ratings in their specs. The lower number is the projector lamp life expectancy under normal use. There are also a higher number of hours offered if you use the projector in Eco-mode. By sacrificing a little brightness from the multimedia projector, you can add many hours to the life of your projector lamp. A good rule of thumb to save lamp hours is not to use more brightness than you need in any given situation. When your projected image does start to dim, AVPartner.com sells projector lamps for most any model of multimedia projector. Projectors for less: Projector Size matters Digital projectors just like most technology products are becoming more compact and much lighter. Today, there are several digital projectors that are less than three pounds, and even a couple that are less than two pounds! Problem is that as the weight goes down, the price of digital projectors goes up. You can save hundreds or even a thousand dollars or more by purchasing an DLP or LCD projector that weighs six to ten pounds, rather than one that weighs four pounds or less. If your shoulder can bear the extra poundage, you'll save plenty of money. Advantages of Wireless Projectors Wireless projectors are becoming more widely available as more people are using wireless in their laptop computers and other technology. The main benefits of projecting wirelessly is as follows: 1. Cabling issues are eliminated which makes your workspace tidier, less confusing, and signal loss through cabling is no longer a problem. 2. Another advantage of projecting wirelessly is that you can switch between multiple PC servers easier. 3. Another advantage of wireless projectors is that the presenter will also be able to have better mobility while presenting without walking around or tripping over wires. Which wireless projectors are the best for your application? The Way DLP Works DLP, short for Digital Light Processing, is powered by a single semiconductor called a digital micro-mirror device (DMD). This semiconductor, invented by Texas Instruments, contains almost 2 million tiny, hinged mirrors. Red, green and blue light is filtered and directed onto the DMD, which switches on and off up to 5,000 times per second. The various streams of light are reflected by the 2 million mirrors and onto a screen, which creates the image. Some high-end DLP devices use three DMDs, one for each stream of light. DLP offers a high-contrast, high-quality image that clearly beats traditional CRT and rivals LCD. Disadvantages to Wireless Projectors With the advantages that wireless projectors offers, there are a few disadvantages as well. 1. With wireless projection, there will be a slight delay when you give the projector a signal. 2. You cannot project full motion video in real time when projecting wirelessly. 3. The wireless projector will cost a little more than an equivalent projector that is equipped with standard cabling. 4. There are possible security issues with wireless projecting. Protect your projector: Projector Ceiling mount Out of sight, out of mind. Ceiling mounting a projector is one of the most professional-looking ways to mount a projector. Plus, it makes it difficult to get to, and difficult to steal. There are also projector ceiling mounts that are available that feature an alarm built into them for added security. If you do have a ceiling mounted projector, you must make sure that you do not forget to clean the filter each month. Resolution For Projectors The two most common resolutions for projectors are SVGA (800x600) and XGA (1024x768). Higher resolutions like SXGA (1280x1024) will dramatically increase the price you should expect to pay, simply because the quality is outstanding. VGA (640x480) has been used for many years in the past, but is no longer an acceptable resolution and you would be hard-pressed to find modern projectors that support it. XGA is generally thought to be the standard and can accommodate 95 percent of all applications. Ultra Light Projectors If you want an easily portable projector, think ultra-light. It can weigh as little as 4 pounds, making it easy for anyone to carry around. You won't find less features or options just because it's smaller either, as the features you find in standard projectors will be available in an ultra light projector as well. Just remember that ultra-light portable projectors are also easier to steal. So make sure you have solid security for your projector, too.
