If you are planning to use this unit with the lights on, you might need to consider the fact that just about any projector is going to look better with the lights off or very little light. If you plan on having a great deal of light running your going to need a pretty bright unit. Plus how much do you plan to spend? Frankley you could do better than that unit for a little more or a little less. But the deeper the contrast the better the picture all around. Blacks and darker footage will look more detailed and vibrant with higher contrast, and so will color saturation and color depth. 600:1 is fairly weak unless the unit is boasting 2000 lumens or more. it might be advisable to do a great amount more research. After all it is an investment that will be used and watched by a great many people. Best to find a unit with the best price, highest contrast, and brightest lumens you can find. And one with a good reputation.

Hi, I had an infocus x1 with 1600? lumes and 2000:1 contrast Ratio( but got it a few hun hours short of its bulb life expectancy, found in daytime picture very washed out in dark at night not bad but color still week ,I now have a choice betweena Panansonic PT-735U 2600 ANSI 300:1 CONTRAST r, OR A SANYO A4500 LUME 1000:1CONTRAST, HOW WILL THESE WORK FOR HOME THEATER/ WHICH WILL BE BETTER?
mY HOME IS OPEN CONCEPT SO TILL NIGHT FALL I WILL ALWAYS HAVE SOME AMBIANT LIGHT,(Sorry bout the caps I forgot to take them off lousy typerany how I read contrast ratio means nothing if there is some light? but what can I expect from these units in a Darkened enviroment?

I wouldn't even use a projector in a bright environment as a daily viewer. The Epson 550 is very striking as an option.

But, neither of what you listed will perform that well as neither are home theater projectors at their core. They are business projectors so image quality will severely be limited by the quality of the unit at the core.

A home theater projector may give up a bit to give out more lumens, but if you need it, at least at the core of the system you have a solid foundation.

What you can expect from either of those units is less than lavish home theater. Niether unit will work all that well for home theater especially where contrast is concerned, which is a must for a good deep color saturation and black levels.

From my personal experience, none of the mid range or less lcd or dlp projectors can hold a candle to crt based projectors.
Something about a 10000:1 contrast ratio and film like image quality...
imho.. btw.
