Yes, lumens matter because they relate to brightness.  Rather than me
defining it, this came from the Sharp website:
----
"What is the difference between ANSI Lumens, lumens, and lux?

An Ansi lumen is a standard measure of the brightness and uniformity of
a projected image. The ANSI lumen does not assume that the projector's
light source is uniform, so to measure uniformity as well as brightness,
it divides the projected image area into nine equal areas, measures the
brightness at the center point of each area, and averages the
measurements using a standard ANSI test pattern.

A lumen is a measure of the brightness of a uniform light source of one
candle. A lux is a measure of the illumination of an area lit by a
uniform light source, and is equal to one lumen per square meter.
In the projector industry, the ANSI lumen is the standard unit of
measure for brightness and uniformity. The lumen and the lux are
standards in other fields such as optometry and photography."

ANSI stands for American National Standards Institute.

XGA has a resolution of 1024 x 768, whereas SVGA is limited to 800 x
600.  Just like a computer monitor, the images should obviously be much
sharper at XGA resolution since there are more pixels, so more points to
add to the quality of the image.

In my opinion, an SVGA monitor should work for you just fine.  The
Infocus X1 gets wonderful reviews for home theater use as a low end
projector (it is less than 1k) and it is SVGA.  I demoed the X1 for
about a week and was very impressed with the quality of picture for the
little price tag.

Good luck and I hope this has helped you.

I am looking to purchase some new or refurbished projectors for the
school I work in.  In looking some over I have found three questions
that I have.

1.  Do Lumens matter?  If so, how?

2.  Is there any significance to ANSI Lumens?

3.  Most projectors are listed as SVGA, but a few are XGA.  I assume XGA
is a more advanced offering, but what is the difference, if any?

Thanks.
