Good Evening,

I'm an elementary school PE teacher that wanted to have a large flat screen TV, pair of speakers, and an Apple TV installed to enhance my classes. You can get a rough idea of what I was thinking here (which is what another pe teacher did: https://www.thepespecialist.com/tv/

My new principle heard of my project and kinda blew it up (not that I'm complaining. He's wants me to look into projectors now, which will allow us to turn the gymnasium into a true all purpose room. Projector would be primarily used by me during my classes, but it will also be used during various events throughout the school year (back to school night) type events.

Anyway, my gym is your typical 80's type gym (basketball court with about 4 feet of additional space beyond the side and end lines. It's maybe 3 stories high with cinder block walls. The newest part of the gym are the very bright led lights.

So, I'm looking for a projector that can work with bright led lights on. I don't have a screen size yet, so I'm literally at step one. I will tell you that a company quoted us a projector with 9k lumens that was 9k and I believe my principle near $^%* himself. The total price of the project was 44k and that's never going to happen.

Can anyone help me with a bit of guidance / suggestions.

Thanks!

The things to obviously keep in mind that a projector isn't designed to be way up in the air, like at a gym and show an image down at viewing level. So, it typically must be installed on the same wall as the screen or the opposite wall.

Same wall requires a ultra short throw projector. These are tough to find with the light output you would need to fill a screen more than a 100" diagonal. Which is relatively small. You will still have to deal with the potential for kids hitting it and damaging things.

Opposite wall from the screen has different issues in that the throw distance is VERY far. So, you need to have a long zoom lens which can shrink the image down to the size you are looking for.

I run about a 160" diagonal in my home, and projectors can hit that size, or a bit larger, from 20-30 feet away, but if the space is wider, then you need a projector with interchangeable lenses to get the size you need, which (of course) adds budget.

I would look at the Epson Clearance store and through their website, but you will really need to dial in some additional expectations.

You also need to consider maintenance for lamps on the projector, and if this is to be mounted, which it typically is, then you need to have a properly protective and ventilated box around the projector to keep it safe and secure.

So, I could see getting something like this:

Then doing a lot of math to see what size screen you are going to get compared to what size you may actually want.

Ok, so maybe I can clear a few things up to help in the process.

1. Projector would be mounted to the ceiling rafters from whatever distance to the screen is recommended. Yes, it would need to be properly protected.
2. The screen would be mounted brighter then typical viewing area (1 for safety) and (2 for optimization of the projector).

Maybe I’ll try to block out everything and attach the quote so you can see what they listed.

I was on a projector stores website and was recommended the Epson PowerLite Pro G7905U Projector. Thoughts on this projector to a 12’ screen from a distance of maybe 25’.

Thanks!

So, the projector you listed is similar to the one I listed but is 1,000 lumens brighter. One thing that definitely comes to mind is that if you intend to put this 30 or so feet up in the air, you will have an image that is over 20' to the bottom, and just a few feet from the top of the gym. This is not avoidable as projectors are meant to project in a straight line, not 15' down a wall. So, you will need to be aware of that.

As well, you will want to consider maintenance and lamp use. As replacement lamps will need someone one a ladder that high up in the air on what is likely to be an annual basis, depending on usage.

Keeping in the same category of brightness, if you are putting the projector in a less than accessible location, I would recommend a solid state light engine (laser) so there are no replacement lamps.

From this page:

The L1200 is a 7,000 lumen WUXGA model with laser light engine.

Similar to the model you listed, but adds the solid state light engine.
