The replacement of projector bulbs is an all-too-frequent occurrence for anybody that has owned a home theater projector for any length of time. While a two thousand hour lifespan may sound like a lifetime to some people, rest assured it is not long before the projector lamp will need replacing. There are however, some general tips that can help to expand the life of a headlamp for the projection unit.

Do not touch the lamp with bare hands One of the most frequent problems encountered is people replacing the bulbs with their bare hands. While this is fine for an ordinary light bulb, it is not a good practice for a projector lamp. The lamp in a projection unit burns much hotter than any regular light bulbs. The effects of touching it with bare skin are equally magnified and problematic.

Touching a projector bulb with the bare skin leaves traces of oil on the lamp surface. While this may seem a very minor detail, it is detrimental both to the bulb and the quality of the resulting multimedia display. The oils will get burnt onto the lamp and drastically reduce the lifespan. As the oil is baked into the surface, it actually diffuses the light being projected, reducing the lumens actually being sent to the refractive surfaces. The light will not be enough to project the image that has come to be expected from the home theater projection system. While the problem may not be noticeable at first, over the course of a little time, the quality will degrade to the point of not being viewable.

Turn off the projector power after turning off the lamp

It is highly recommended to turn the power on the projector to the “off” position only after having turned off the lamp and allowing it to cool. This will allow the cooling fans to do the job they were designed to do. While rapid cooling and heating result in repeated contractions and expansions of the bulb filament, it is much better that it be done more quickly with the cooling fans. Likewise, turning the projector on and allowing the cooling fans to run for a moment before turning on the lamp will help as well. This will add hours to bulb life expectancy and allow for longer hours of viewing pleasure on the home theater projection system.

Over the years, I have grown really attached to my home theater system. I must say, of all the rooms in the house, my own little movie theater is the one I could not live without. I am absolutely in love with my home theater system and, if you are anything like me, I am sure you will love yours too. I found, when I was initially building my system, that there was so much information to absorb. Every product out there seemed better than the next, and I found myself unsure about which to buy. Here are a few things to keep in mind when shopping for a new home theater projector.

There are two main types of projectors on the market; DLP and LCD. DLP stands for digital light processing. It was invented by Texas Instruments, and utilizes a microscopic array of over 2 million mirrors. DLP has a higher contrast than LCD, but there are some unfavorable consumer reports that note something called the “rainbow effect”. The “rainbow effect” is noticeable when looking from one side of the screen to the other, and is characterized by a sudden burst of color.

LCD stands for liquid crystal display. These projectors have three distinct glass LCD panels inside; one for each component of the video signal (red, green, and blue). While DLP chips reflect light, the LCD panels allow light to pass through them. LCD projectors produce brighter images, and they are known for having excellent color saturation. In the end, you will be hard-pressed to notice a great difference between the two types of projection systems.

When shopping for a new projector, keep your particular needs in the forefront of your thoughts. As I mentioned above, it is really easy to lose yourself in the minutiae of each particular system. Connectivity is a definitely something to be mindful of. Make sure that you are able to connect all of your components, including your gaming system. Nothing beats playing Halo in real-life size! Contract ratio is another important factor; the higher the ratio, the better the picture will be.

The brightness of your projector is another thing to consider. Light output is measured in ANSI (American National Standards Institute) lumens. You will want to avoid a projector that produces anything shy of 1000 lumens. As you are likely aware, the projection resolution is extremely important. This refers to the number of pixels that can be displayed on the screen. Go for something that is no less than 1024×768, as this will allow you to fully appreciate the depth and quality of HDTV. In the end, you should buy the projector that is in line with your needs and your budget. Soprano’s is coming on right now! Time to go!
