I was the "projectionist" at many meetings during graduate school, as a
way of earning a bit of extra cash. I was always in a dilemma as to
whether to let the fan on the projector run or not, after turning off the
bulb. I have heard *extremely opinionated* "experts" argue both ways: one
says cool the bulb quickly to extend lamp life; the second schools says
let the bulb cool slowly to extend lamp life. After much angst, thinking,
and weighting of opinions, my decision was the second (ie, don't run the
fan; let the bulb cool slowly at room temperature), but I'd like to hear
informed (= rationally stated & reasonably supported) opinions either way.
Second question: Glad we're talking about Leitz projectors. I own a
pradovit n24 which has worked well for me, but I burned out the bulb and
can't find a replacement. Suggestions? It's pretty worthless without a
bulb.
I've tuned out the past couple of digests, and see that in the meantime
we have produced the thousandth olympus digest! Wow, are we a bunch of
windbags or what? (Question: Once the light has gone out, should you
allow the windbag to continue blowing?)
