I'd guess, you'll have a real long wait for a projector. :) I'd suspect any manufacturer would not be forth coming with a projector if one of the requirements was to put 300 hours on it. It's tough enough to get one, much less long enough to turn it on.
OTH, my own suspicions would lead me to believe the decline in Ft.Lamberts over 300 hours would not be significant, and, if you're starting out fresh but just barely on the upside of minimums, you should not be flying that airplane anyway (I mean, using that screen material). Understand, we have been speaking of Ft.Lamberts in the range of 14-17. I've seen many where the picture was hovering at 8 very nicely (typically from a CRT).
Actually, to become "Design Cinema Certified" (now that carries about as much weight as a flea), I'd like to see the following specs listed at 50% of the rated bulb life:
Lumens at 6500K at 30%, 50%, and 100% white levels (or 70%, 50% and 0% gray).
