Okay this is loosely related to lighting, but it does have to do with light. I am talking about a projector for my theater. Who here is honestly surprised that the school cut it out of the renovation budget, only to 3 years later realize they need one? Well the head of school has finally given the go-ahead for us to get a mounted projector. I'm praying they wont' half ass this too but not running the cable, or not running the cable to the stage, so we can't use it with powerpoints. Unfortunately this is running through the Technology Dept., not Theatre Dept, so I have to work closely with the computer teacher on this one. He encouraged me today to write a note to the head of school outlining what we need. As I have no real knowledge about projectors, and mounting them, I hoped some of you could shed some light on this situation. I don't want the administration to mess something else up, so I wanna make sure we get the right projector in the right place. My questions include: -What is the appropriate number of lumens? I think we are looking at 75ish foot throw. -What is the significance of contrast ratio, and what should I look for? I'm afraid it would get washed out during the day, as the company who installed our curtains messed up, and light pours through the windows. -Is resolution going to be a factor at this distance? -What types of features are on various projectors, what should I look for? What differs on a projector the designers assume will be deadhung for presenting applications? -What type of airflow do these need, if any? -Will long runs of video cable degrade in signal quality? -What is the best place to hang? Up on the ceiling keystoned to high hell, straight on from a back of house pipe? -Where are these commercially available? -What is the ballpark price? -What is the lamp life in hours going to be around? Thanks guys (and gals), I had a hard time finding this detailed information on my own.
