Good question and I don't know the answer. I do know that running an
LCD at reduced level will do nothing either way regarding life of the
unit - unless they reduce the light level of the backlight for overall
settings which is a possibility. I've heard of varying the backlight
dynamically to increase the contrast ratio number as we consumers fall
for 'bigger is better' even when it can be proven false. Varying the
backlight dynamically would have all sorts of oddities but statically
changing it with the controls wouldn't be bad assuming the color
temperature is constant.
It's only one unit but our 4+ year old Samsung DLP currently has
around 10,000 hours (was 9100 a few months ago) and has its second
bulb and color wheel. I replaced them - it's considered user
replaceable - for a total cost of $195.30. I have 2 friends with the
same model with similar stories but that's only 3 units.
As a general rule for all electronics don't bang or vibrate them and
keep the dust cleaned out so that they aren't overheated. Heat is the
number one killer and dust the biggest culprit. Every year about this
time I take the computers in to work to give them a blast with the air
hose (20 - 30 PSI max) and they never look as dirty as they actually
are judging by the size of the 'cloud'.
