I got a free bulb with purchase. I'm only like 1500hrs in, and it's still plenty bright with the iris at -8, so I'm guessing between the two i'll be shopping for a new projector before a new bulb.
that being said, there's enough aftermarket suppliers that even if jvc stopped producing them, you'd at least have an option. that being said, it appears you can still get bulbs for jvc projectors a few generations earlier than the x35, so I wouldn't panic yet.
