With all the Grafik Eye chatter lately, I've started considering my lighting control a bit more. Not sure if I'll go with a Graphic Eye, or bite the bullet and step up to a Radio RA2 setup that I can expand to the rest of the house later. My heat load calc was just back of the envelope stuff. You know, 15 cfm per person, and I figured 160 cfm for an 8" round flex duct. That gives me about 40 cfm extra for 8 people, and I figure anything involving people at the bar will likely have the door open anyway.
Use
THIS link on Lutron's page to see ALL of the LED bulbs and fixtures Lutron has qualified to date. Select Grafik Eye QS from the drop-down menu and hit search. You'll be a bit disappointed with the limited selection, I am sure. Once the selection list comes up you can then click on the hyperlink for that specific fixture or bulb. This takes you to another screen with the more detailed information. I only pulled up the fixtures that could do 1%-99% but in almost every case the
perceived light was in the 15-20% range. Not good. If you find anything remotely suitable please let me know, but this, along with the significant upcharge for LED, solidified my decision to just go with the Halogen. As I said before, Lutron recommends a line made by Philips called Halogena which has great light output with less wattage and therefore less heat.

I originally wanted to place it as you suggested, but again, we're getting close to 20' at that point, and I'm not sure how well the PJ will perform there. On top of all that, my riser is 15", so I'm dealing with the head height, and the PJ potentially hanging down into the sight lines of those at the bar.
If you have any suggestions, or even some feedback about the PJ's brightness at ~19', I'd appreciate it. I'm leaning heavily towards a 6020, and if I could pin down where it's going, that would make my life a lot easier!
Did you settle on a screen size and gain yet? That will have the single greatest determination on your brightness and throw distance. And judging by the fact you are now looking at the Epson 6020 that tells me you are considering an anamorphic lens which takes another 3%+ of light output. The standard Panamorph lens has a focal length that maxes out around 17'5". They say the UH-480 can go up to 20' without any significant degredation, but there is a slight loss in focus.
But let's assume you go with a 130" width 2.35:1 screen with 1.1 gain. That puts your max usable throw distance at 19' 10" and will give you 12 ft. lamberts of brightness. The minimum throw distance is 14'6", fyi. I played around with the tool and the sweet spot is between 16' and 17'2". This will yield between 16 and 17 ft. lamberts of brightness which is right where you want to be. You can get a nice bright image with the projector further back but the tradeoff is that you start to lose contrast and color saturation.
Since you have good ceiling height and an unobstructed throw to the screen, your projector can essentially be flush-mounted to the ceiling with only a minimal gap. No one would even come close to hitting their head. In fact, even on the riser with a hush box I bet you still have 7' of total headroom at a minimum. So it might feel weird to have something that close above your head but realistically it is still higher up than a standard door frame height and people walk through those all the time.
Let me know about your screen size / material when you can.

Now I'm starting to wonder if there's anything I've forgotten to do pre-drywall. I don't think so. The way my room is situated and the way the joists run, most of my wiring will go in from two penetrations, and I'm planning to run it all inside my soffits. So aside from the 2" conduit for the PJ, there really wasn't anything else I needed to run outside the theater. I'm open to suggestions, though.
