My old projector, IN72, blew a capacitor and while I will attempt to revive it by replacing the capacitor it is time to get into Blu Ray and 1080p resolution

I have narrowed down my projector choices to the JVC HD250 and the Sony VWPro1. I am leaning toward the VWPro1 because it has a more complete color calibration system and it is a brighter projector (1300 lumens vs. 1000 lumens) although it gives up the black levels that the JVC is known for. Both projectors are relatively quiet, which is an important consideration for me.
Here is my issue: My projector distance (ceiling mounted) to my Elite Cinetension 120 inch Cinegray screen is approximately 17 feet 8 inches and while this is within the zoom range of the Sony is it toward the far limit and I understand that this will reduce the light output. The JVC, while having a lower lumen rating, would be right in the middle of the zoom range. Does this negate the higher lumen rating of the Sony?
I have only viewed my IN72 on low output for the best image quality and didn't have an issue with brightness in my light controlled home theater. I couldn't find specs for "best" (i.e. low output) for either Sony or JVC models.
Has anyone mounted either the JVC HD250 or Sony VWPro1 about 17 and a half feet away from a 120 inch screen and can comment on the light output?
My goal was to get approximately 16 fL off of the screen but I am questioning whether this is possible with my set up. Remounting the projector would be difficult as the wires are run in ceiling, which is double sheetrocked for sound proofing.
Thank you for your feedback. I didn't think getting a new projector would be so difficult.
Kind regards,
Tom
