If new bulb gives full output and in 1000 hours gives little output what average figure can we use for its life?

If 50%-then that should be used in FL=Lumensxgain/screen area calc.Let it rip.

I know DILA bulbs lose half of their brightness over their short life-span, but I do not believe every projector loses as much of its light over its lifespan as well.
