Hi you guys. I just found this thread and I love the designs!
Let me just throw out my view on the soffit size. I know that when I painted pkinneb's ceiling, they were a little lower than I suggest, but it worked out. I would say try not to go any less than 9", if at all possible. If that's all the space you have, then that's all you have. I believe, and pkinneb can correct me if I'm wrong, but I believe he is also using a blacklight floodlight that sits on the floor and is aimed up at the ceiling. Depending on the size of the room... a floodlight might not be needed, but if you want the center of the ceiling and the sides so look similar when you turn out the lights... then it might be needed. Usually, the outside edges of the theater, just above the lights in the soffit, will be supercharged and the center area will not be glowing quite as brightly. Usually within about 10 minutes... all of the stars will blend together and they will all be the same brightness, but if the first 10 minutes of different brightness would bother you, then I'd suggest a blacklight floodlight.
Actually, I'd say that most ceilings, even with 12" soffits to even 18" soffits, will show that difference in the brightness that's around the perimeter and in the center just because the perimeter is so close to the soffit lights that it just can't be helped. The more space you have from the soffit to the ceiling the better, but you work with what you have and then adapt from there. I love the look and convenience of blacklight LED strip lights around the ceiling. They look nice and charge most of the stars. If you think it is then needed, or you just want to boost the center area... then you can always add a blacklight floodlight to the mix.
I hope that helps and doesn't throw more wrenches into the mix.
