22" TN panels usually have two fluorescent backlight tubes inside--
one at the top screen edge, and one at the bottom.
24" panels apparently use more tubes... two on the edges may not be
enough to evenly illuminate a screen of that size. I'm not sure of
the arrangement, though, having yet to peek inside one. From reading
spec sheets, there's a big jump in power consumption between 22" - 24"
sizes, and backlighting is always the main contributor to that.

Have you tested a 22" at maximum brightness? My 216BW at home (21.6"
16:10) is way *too* bright at 100%. Working in a dim room, usually 0%
is plenty for text work (at only 18W, nice). I'll bump it up to 5-10%
when watching movies.
This depends on the intended use and ambient light conditions, of
course. Trying to use one outdoors, you'd certainly need all the
brightness you can get, or perhaps a transflective panel...
All LCD monitors will gradually dim over time as the tubes age, just
like CRTs, so it's good to allow some extra brightness headroom with
that in mind.
