LCD Projectors (Liquid Crystal Display)

LCD Projectors function by spotless light through transparent LCD cells. Most LCD projectors us advanced polysillicon LCDs, which use three separate color panels (red, green, and blue) to produce the preferred color. Projected images are produced by the combination of light shinning through the LCD cells. LCDs have excellent color saturation, usually have adjustable brightness and contrast, are typically brighter than DLPs at the same lumen output, and they have a broader range of connectivity.

DLP Projector (Digital Light Processing)

DLP projectors were developed by Texas Instruments and project images by reflecting lights against hundreds of little mirrors called digital micro devices (DMD). Each mirror representing one pixel is powered by electronics that adjust the angle of the mirror according to the color being displayed. DLP projectors are lighter in weight than their LCD counterparts. They are all digital technology and typically have higher contrast ratios, meaning that they project video images better than LCDs. They are portable, tend to be smaller and lighter than LCD projectors and connect easily to other digital devices.

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 cut down the lamp life, or of poorer quality, it could cause the projector lamp to burst.

Changing the projector lamp:

A projector lamp will gradually lose clarity over time. In fact, the curve is so slight that you may not even notice it. When your presentation or video has dimmed so much that you can hardly see the image, it’s time to order a new projector lamp. Another way that you’ll know that you need a projector lamp replacement is by viewing the total lamp hours used on the projector. All projectors have a built-in lamp hour counter that starts at zero when new, and should be reset once you change the projector lamp. You should be able to find the total projector lamp hours used within the menu system of your projector. Consult your users’ manual for instructions on how to check projector lamp hours on your model of projector.

Allow projector lamp to cool:

A filthy projector filter will cause it to run hotter and might cause the projector bulb to burn out prematurely. Therefore, we recommend cleaning the projector filter once a quarter with a can of compressed air. If your environment is smoke-filled or dusty, you may need to clean the projector filter monthly. The result of cleaning your projector filter regularly may result in additional months of use from your same projector bulb.

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.

Avoid dangerous 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 instantly. You must allow the data/video projector to warm to room temperature before turning on the projector to avoid the unsafe situation of an exploding projector lamp.

Price: $365.27
BenQ 60.J3416.CG1 Projector Lamp for DX660 DS660 DX650 DS650 Compatible Projector:DLP Lamp Power:210W

Brighter projectors tend not to have long lamp life, and this is what barred normal consumers from wanting to buy these machines. It wasn’t until manufacturers like BENQ came out with projectors like the DX660, that brightness became inexpensive.

The BENQ DX660 has a lamp life of 2000 hours, and this is quite amazing considering its brightness. It employs a 210W projector lamp, combined with an ultra efficient cooling system. The cooling system is what allows this lamp to last as long as it does.

The BENQ DX660 is a DLP projector, but unless you are ultra-sensitive, you most likely will not see any rainbows Dorothy. Resolution is pretty efficient at 1024×768 native, and a compression ability of up to 1280×1024p. This unbelievably wonderful resolution is coupled with HDTV at 1080i making viewing a pleasure, especially if you spend a little extra for those HD Sports channels.
