As you hinted to, this is the hidden cash cow for the projector industry.
I have an epson 5000xb (or similar) that blew (exploded + shattered)
the bulb at around 200-500 hours. MTBF is not a warranty! :-(

I would be interesed in hacking something together to replace the
bulb, even if it is not the same brightness. I am not about to pay
$400 for a light bulb for a $800 projector. Perhaps we can compare
notes? :-)
