Keep an eye on the point

There are a few things to keep in mind when using an outdoor projector. One of the most important things is brightness. An external projector never works properly under the sun.

The reason for this is that there is no projector brighter than the sun. If you are using a projector, make sure you do this after sunset. Another challenging part of using an external projector is the number of lumens.

What is lumen, Lumens do I Need for An Outdoor Projector?

The American National Standards Institute or ANSI defined the lumen as the measurement unit for the projected brightness. ANSI Lumens consider several factors when measuring projector brightness, including using a white area for baseline comparison and measuring brightness in nine different locations on the screen before averaging the overall projector rating.

What is an outdoor projector?

One output device that distributes an image over a large surface is a projector. A white screen or divider is an example of an external projector. This is in contrast to a monitor or television offering where many people present pictures and videos.

Originally, external projectors were advantageous at conferences or meetings. Outdoor projectors can come in many shapes and sizes. But it’s usually about a foot wide and tall and an inch long.

How many lumens are required for a projector?

Lumens are directly related to the brightness and clarity of your external projector’s display. This is directly related to your image’s quality, as it is the light emitted by your external projector.

This is the brightness of your projector. A brighter picture leads to a clearer picture. If you project an image externally, the brightness level plays a significant role in your final image quality.

The natural light outside also interferes with the brightness of the projector. For this reason, it is always recommended to use an external projector in the dark, so the picture is clear.

If you choose to use external projection, image quality should be your top priority. You do not want your picture to be distorted, blurred, or dark. Therefore a projector with a larger lumen should be chosen.

The higher number of lumens is more spectacular than the image. The more sensational the picture, the more precise the scene; although projector prices increase as the number of lumens increases, a person should always select the maximum lumen within their price range.

Projection Screen Size

Projection Screen Size

Projectors usually emit light in a cone that hits a circular point in front of them. This cone is sharpest in the center, just in front of the projector lamps, and closes at the edges. Ideally, your projector can illuminate a circular area that is larger than the entire screen so that the screen lighting appears even. This means that a sufficiently high lumen output is also required to fill a larger room with relatively bright light.

However, projectors fall into different classes, so you can’t just use a simple office projector or home theater model in a conference room even if you move the projector away from the screen so that the cone of light spreads out more and falls over a larger area because the projector only has a certain amount of lumens (light) with particular intensity. It can emit, which means the image fades out quickly. Also, the fact that the projector optics are only made for a specific operating range means that the image is increasingly difficult to focus on moving away.

What is the best project solution?

Turn off the maximum light. Align your screen so that the projection surface is protected from ambient light. If you’re doing your best to control the outside conditions, use a bright outdoor projector! More lumens is better. We recommend:

  • 9×5 ft screen – at least 2500 lumens, 3000 lumens is ideal
  • 12×7 ft screen – at least 3000 lumens, 3500 lumens is ideal
  • 16×9 ft screen – at least 3500 lumens, 4000 lumens is ideal
  • 20×11 ft screen – at least 4000 lumens, 5500 lumens is ideal
  • 25 x 14.5 foot screen – at least 5000 lumens, 10000 lumens is ideal
  • 40 x 22.5 foot screen – at least 5500 lumens, 12000 lumens is ideal

Why are lumens important for projectors?

Think of the room your screen is in. How much natural or artificial light is there already in this room? Pay attention to all windows, lights, and connecting rooms.

 A good rule of thumb is that the more light there is in your room, the more lumens it needs.

As a result, when installing your home theater in a room with blinds or curtains, you don’t want the most significant number of lumens possible. Which will damage your eyes?

The brightness can also affect the picture quality. The colors may look washed out, or some images may be challenging to see.

The ideal number of lumens depends on where and for what purposes the projectors are used. Also, the size of the projection surface is an important factor.

How to choose the best projects

There are a few factors to consider when choosing the best outdoor projector for your needs.

Picture quality

For an external projector to deliver a high-quality image, 2,000 lumens is the lowest brightness you can get. Outdoor projectors should also display at least HD resolution to achieve sufficient image quality. The Optoma UHD60 deserves our top spot due to its incredible 3,000-lumen output, high-quality 4K resolution, and massive contrast ratio.

The screen

In addition to these very important specs, consider buying a screen, or what will do on the side of the house or on your garage door.

Film source and sound

Consider the source of your movie – would you need to bring out a laptop or game console? Or is the projector compatible with a smart dongle? Some useful external speakers always help too.

Buy the right projector

When you are ready to buy your projector, there is an easy way to find out how many lumens you needed. Before you go to the store, consider the following questions, and refer customer service to the right projector.

  • Where do I place a projector?
  • What is the distance between the projector and the screen?
  • How much natural light is there in the room?
  • Do I want to turn the lights on or off when using a projector?
  • How big or a screen do I need or already have?

With these 5 points, you have already reduced the number of lumens you need.

For example, suppose you set up a home theater in your living room.

You mount your home theater projector on the back wall so that it faces the screen. Hence the distance is about 10 feet. The screen is about 100 inches. Natural light comes from the windows, but all indoor lights are off when you are watching movies.

Since the screen is small and has natural and artificial light, you should look in the table above for a projector that emits 2,000 to 4,000 lumens with medium indoor light.

This way, you can leave the lights at any time or turn them off for movie nights.

With so many options, you have the chance to find the best projector for your needs.

Give it a try, and if it doesn’t work, try a different setting to take it back. The home cinema, the presentation, and the gaming experiences are unique for the viewer.

How to set up outdoor projector

Installing an outdoor projector is usually not a complicated task. It may take some time to use, but once you hang, you will be up and running in no time. Here are some tips to get you started.

All projectors are different. Some of the most common types and builds for these tips are.

There are a variety of outdoor projectors that come with a base and a screen. These sets are generally very easy to assemble and disassemble as the kit includes all the parts. However, they can be challenging. So make sure you have some help.

There are some outdoor inflatable projection screens. These are incredibly lightweight, easy to install, and can withstand light winds. The only real downside to the inflatable projection screen is that the fan may have to run the entire time to inflate it. This can cause too much extra noise, which can make the event worse.

When installing, be sure to speed up the field of view, screen area, and projector area. You want to plan individual elements as well as a little extra space for maintenance or emergencies. Make sure that your projector is set to the optimal angle and distance from the screen. You also need to ensure that it is high enough to avoid disturbances of people walking.

Check the screen angle and write sunrise, noon, and sunset conditions. If you can keep your screen near a natural shade in the afternoon, it helps to see your daylight.

Make sure you have easy access to the power supply. You want to cover the cable and identify and trigger hazards.

Be sure to test well at your preferred venue before the event. This allows you to customize your setup for any unexpected problems.


The number of lumens is usually stated on the packaging of an external projector. Always make sure to check the specifications of the projector before making a purchase. Also, check the image result from an external projector and meter if your image is bright and satisfactory.
