Lumens Guide

Ansi-Lumens

Projector brightness is rated in lumens.

A lumen rating indicates the overall brightness that a projector is able to produce. Lumens are actually dimensionless, so the lumen output of the projector is static and has nothing to do with the size of the image. However, the size of the image has everything to do with how bright the image you see is. For example, the larger the image is that you are trying to create, the brighter the projector will need to be if you want to overcome ambient light and still see a nice, vibrant image.

Below is a set of standard rules intended to help you select a projector powerful enough to overcome the environment you'll use it in.

Selecting a projector that is equal to or greater than our lumen/brightness recommendations will not be detrimental with regard to performance, however it may cost you more money than you need to spend. These rules are simply guidelines to use for a bright, high-contrast image, but they are not set in stone. Projectors with lower outputs than our lumen/brightness recommendations will still display a viewable image, but they may not pack the "punch" that many come to expect when watching business related materials.

If you have further questions, or will use the projector in a manner different than described below, please don't hesitate to call us for further assistance on 0800 170 7012.

1. I am creating an image that is = 6 feet in width

In a 100% light controlled room - 1000 lumens should be sufficient
In a room with some ambient light, but no direct lighting on the space you plan to project the image - 1000 lumens should be sufficient
In a room with the lights on, but no light directly over the area where you will project the image - 1000 to 1200 lumens should be sufficient
In a room with bright ambient light - 1400 to 1500 lumens should be sufficient
I don't know how bright the room will be, but I do know that my image size won't surpass six (6) feet - 1500 lumens to ensure that you will overcome all lighting conditions should be sufficient

2. I am creating an image that is between six (6) and eight (8) feet in width

In a 100% light controlled room - 1000 to 1200 lumens should be sufficient
In a room with some ambient light, but no direct lighting on the space you plan to project the image - 1200 to 1400 lumens should be sufficient
In a room with the lights on, but no light directly over the area where you will project the image - 1300 to 1500 lumens should be sufficient
In a room with bright ambient light - 1500 to 1800 lumens should be sufficient
I don't know how bright the room will be, but I do know that my image size won't surpass eight (8) feet - 1800 lumens to ensure that you will overcome all lighting conditions should be sufficient

3. I am creating an image that is over eight (8) feet wide but less than ten (10) feet wide

In a 100% light controlled room - 1500 lumens should be sufficient
In a room with some ambient light, but no direct lighting on the space you plan to project the image - 1500 to 1800 lumens should be sufficient
In a room with the lights on, but no light directly over the area where you will project the image - 2000 lumens should be sufficient
In a room with bright ambient light - 2000 to 2500 lumens should be sufficient
I don't know how bright the room will be but I do know that my image size won't surpass ten (10) feet. - 2500 lumens to ensure that you will overcome all lighting conditions should be sufficient

4. I'm creating an image over ten (10) feet wide but less than fourteen (14) feet wide

In a 100% light controlled room - 2000 lumens should be sufficient
In a room with some ambient light, but no direct lighting on the space you plan to project the image - 2000 to 2300 lumens should be sufficient
In a room with the lights on, but no light directly over the area where you will project the image - 2300 to 2700 lumens should be sufficient
In a room with bright ambient light - 2700 to 3200 lumens should be sufficient
I don't know how bright the room will be, but I do know that my image size won't surpass fourteen (14) feet - 3200 lumens to ensure that you will overcome all lighting conditions should be sufficient

5. I'm creating images for very large audiences that will surpass fourteen (14) feet in width
