Canon REALiS WUX6000
Projector Specs

We are having a lot of fun doing church in an AMC movie theatre and currently using their old Sanyo PLC XP57L XGA projector at 5500 lumens. This is what AMC used for running trailers and pre-movie advertisements before they went completely digital. Our theatre has a throw length of 63ft. The horizontal screen size is 40ft. Using the Sanyo the image is a little dim - but fits the screen fine.

Using the Projector Calculator on I can't seem to get my configurations to fit our distances with any lens for the Sanyo PLC XP57L. Can anyone help? I must be doing something wrong.

The reason we are researching this is because we would like to purchase our own projector and save the $100/week they are charging for using this projector. The Canon RealiS WUX6000 looks like it would do the trick with an upgrade in image resolution and 500 lumens more brightness.
The calculator on Projector Central states that we should get 5fL of brightness on the screen with our dimensions. This doesn't seem like a lot - but is likely to be pretty similar to what we get using the Sanyo. I've read that 12-22fL is ideal for a dark room, so 5fL seems pretty low considering the room isn't blacked out. Our lighting is pretty controlled. We use some focused Source 4 pars from the back of the theatre to light the band/stage area (front of theatre) without too much light bleeding onto the screen. We also have the theatre's down lights on during worship otherwise it really is too dark for people to see each other.
I've attached an image as an example.

Any suggestions or experience with this kind of setup as we look to upgrade projectors would be welcome!

I'm not sure what to say. A 40' wide image can be hit from the aforementioned Sanyo, to fill the width, using their LNS-W31A, Short Zoom Lens. It allows for the 40' wide image to be hit from 51' to 73'2".

But, it measures only 2 lumens per square foot at that size and that setup. That's incredibly dim if it is indeed filling the full width. Also an issue as the screen likely is not a 4:3 aspect ratio, but more likely 16:9 or 2.35, so much of the light is falling off the edge of the screen (33%).

The screen size called for with that projector is 30'x40', which is 1,200 square feet it is trying to illuminate, which is huge. Commercial projectors run about $80,000 or more to deliver those 12 lumens or so that actually end up on screen.

I'm not sure of your budget, but I would strictly limit the search to LCD projectors and widescreen projectors so that the lumens that come out of the projector actually fall on screen.

The Canon is a decent model and will deliver a fair bit more light on the screen since it's natively widescreen.

If you weren't unhappy with the resolution/detail you were seeing before, then spending more for more resolution makes a lot less sense then spending more for added brightness. 1920x1200 won't fix your lumen issue.

I would lean towards the brighter Panasonic models which are more affordable...

For example:

With the ET-DLE150 lens, can throw a 40' wide image from 63' lens to screen. (56' to 80' actually).

Realistically, this size of screen is traditionally handled by 15,000 to 20,000 lumen projectors. If you are using it once a week, and intend to continue to do so for at least two years, then spending $10,000 on a projector isn't unreasonable, but I would focus on brightness first.

This is my search list that I am (kind of) using...<g=&t=&db=&dt=&c=&ar=Wide+%2816%3A9-10%29&dvi=&wr=&ol=1&pjl=&pjw=&pjh=&td=&is=&i=d&tr=&oop=1&sort=brt

You can change the brightness parameters to get a model which is appropriate.

You could always consider a double stack of projectors, which takes a lot more setup time, but doubles brightness on screen and can save some money.

Also, not sure if you are truly locked in at that 63' throw distance if you are providing your own projector.

Two of these...

May work if the projector allows for a screen that size, you could get 10,000 lumens on the screen for about 3 grand. More setup time every week, but could work very well.
