1830 calibrated lumens has been done with several projectors now , safe to say it's on the higher side of that number . I watched The Greatest Showman last night in HDR, on a similar screen size I was running 70% laser . Projector is 17 ft back just overhead and behind the second row of seats . Beauty of the VW885 it is small, light weight and extremely quiet, mounting it this close to the screen is no different than any other projector , in fact mine went on the same mount I had there for the VW675, it was in position and running half an hour later. No special mounting, noise deflectors or additional cooling necessary. If replacing a VW1000 it's almost plug and play really as the mounting points exactly the same . My VW885 produces considerably less heat than my previous VW675 or the JVC RS600, certainly less than the VW1000's 365watt lamp .
You can get more lumans from the RS4500 but that will require mounting it overhead and closest to the screen , also running 100% to make the additional lumans to go one size above the VW885 in screen size . The RS4500 is 100LB, it also produces a lot of heat and more noise running high, you'll have to deal with that. Moving it to the back of a room on a shelf with hush box as many have done places the projector considerably further back , you loose the lumans advantage from mounting closest , it all depends on the distance.
For a screen 12ft wide as you have mentioned, the RS4500 would do this but consider the conditions above. For 12ft or more, I would strongly suggest the VW5000 . Designed to be at the back of a room starting at the 19ft range I do believe and produces around 4000 lumens . The VW5000 is a huge projector as well, produces a lot of heat and noise, at the back of the room on
a solid shelf is where it is meant to go I do believe.
There is a eshift 4K DLP laser projector available as well in the 5000lumen range . According to Dave Harper it's supposed to be a fantastic option, maybe you could ask him about that one , find out the pros and cons. Sony is also going to release a new 4K laser projector in the fall, supposed to use the ARC lens . I expect it will have more brightness than the VW885 otherwise it
is going to cross over too much . How much brightness will be interesting, I'm sure they do not want it crossing into the VW5000 brightness territory either . How big will this new projector also up in the air, none of the above will be known until release in the fall .
Good thing is all the options you are considering are good ones , once you have nailed down the screen size, aspect and gain, a better decision can be made .
