hi,

we had bulb "explosions" with our IBM/InFocus projectors in the first 100 hours,
the bulbs shattered and failed; the projectors were also very sensitive to
syncing with the computers so the order you turned things on were critical.

we now have some mitsubishi projectors, which at 2100 lumens in our small conf
room are extremely bright, almost too bright! and they have no sync problems.

No bulb replacements?! Wow. Our Epsons require new bulbs about once a year.
Considering their expense (#300 / $500ish for each bulb), this is quite a
problem. Is it just the Epsons that need so many new bulbs or is it that we
just use them more than you...?
