Choosing a Projector
By: Wally Dalziel
Many churches, when evaluating and selecting projectors for their A/V needs, have questions concerning the following elements of the equipment. Here is a breakdown of the various considerations when purchasing a projector for your worship facility.
Projector brightness is measured in ANSI lumens. Projectors suitable for churches are typically rated from 1500 lumens to 4500 lumens.
If you can control the light entering the church, you save money buying projector with a low ANSI lumens rating. As a guide, a projector with 1500 lumens is generally suitable.
If you have got a lot of ambient light in the room and can't do anything about it, you could opt for a high brightness, high contrast projector. In really bright conditions, though, it is recommended that you opt for a projector over 2500 lumens.
What does contrast actually mean to you?
Essentially, the higher contrast on a projector increases the perception of depth in the image and means subtle color variations show up more clearly. Hence, subtle textures are more visible. It also means that dark scenes do not look washed out.
Looking for a projector with a high contrast ratio would not be too important if you are running song sheets through a computer, although it could be a deciding factor if you are looking to run film nights from time to time.

DVI and component connections are less common. If you have a high-end DVD player that has component output capability, you can take advantage of these connections, so look out for them in the product specification sheets. If you don't have component outputs, you can normally use the S-Video connection.
XGA resolution is inherently superior to SVGA, as it displays about 63 percent more pixels. Of course, this also means that it is more expensive.
The average life of a bulb is about 2,000 hours. Some projectors go up to 6,000 hours. With a lamp module costing about $600, a 2,000-hour bulb works out under 20p an hour of usage, which is relatively cost-effective but may be a price consideration.
