Using the projector in daylight is an opposite term, but the latest technology has made it possible. “How many lumens do you need to project in daylight?” is a genuine question that often comes to the user’s mind. Depending on the quality and strength of the projector, the number of lumens could be different.

Most probably, projectors with a brightness of 2500 lumens can be used in daylight or under-shade outdoor activities. If your projector has 3,000 lumens or above, the image will surely be more precise and brighter for better daylight viewing.

Let’s start with the terms that you should consider for excellent image quality.

Important Factors to Consider

While using a projector to project in daylight, you should consider some crucial aspects that can enhance overall performance.

  • If you use a projector for some outdoor purpose, make sure the sunlight is not falling directly on the projection screen. Because sunlight always has high lumens than any of the best projectors. Therefore, it will be impossible to see images on the projection surface in light.
  • For a better projector screen, the projection surface should be shaded. The lights around should be dim as much as possible. Close the room curtains if you are using them in a bright room because unnecessary sun lighting in rooms causes overheating of the projector lens.
  • A projection screen utilizes a huge reflective surface material for daylight viewing, which differs from projecting film on the wall and assures that you are obtaining the projector’s expected lumens value. Projector screens use the idea of screen gain. Such a notion enhances the reflection value of projection. This indicates that if the projection screen holds the screen gain value of 1.2x and your projector projects 1000 lumens of illuminance, then the observed brightness comes out to be 1200 lumens.
  • Simply we can say that a projection screen boosts up your noted/expected brightness. If you are using a cheap or economical projector, this screen is suggested on a large scale. It can provide its services in a conference room, office, bright room, and serve as a home-theater.
  • You can watch a diminutive screen size if your projector is located very near the projection surface. On the other hand, a projector placed at a considerable distance from the screen results in a larger but faded picture. Many projectors arrive with distinct throw ratios, and they range from long-throw, short throw, and ultra-short throw. The most usual type of projectors are long-throw projectors, and they create a 100-inches screen with suitable brightness at a separation of 8-12 feet.
  • If you are using the projector in expansive rooms such as a classroom or presentation room, make sure no light is entering the room. I mean control the ambient light and direct sunlight as much as possible. Even it is necessary for a better viewing experience without squinting your eyes. However, if you consider dimming the room up to 50% and using the 3,000 lumens projector, you will find a significant difference in image resolution and quality.
  • Projecting on a wall could be the worst experience if the wall does not have projection paint. Because ordinary paint absorbs maximum light instead of reflecting it. Even it is not recommended to use a wall for projection during the day or night.

Importance of Brightness:

While projecting an image or video through a projector in daylight, you should remember a few things. As you know, straight sunlight will make any projector light dim and blurred. However, by using perfect lumens on your projector of choice, you can manage daylight normally or ambient light in a meeting room. Keep in mind that the key factor remains the projector’s general brightness and maybe the reflectivity of the screen you’re utilizing. Overall, brightness is one of the essential factors.


Projecting quality depends on the contrast ratio, resolution, and brightness of the projector. All these terms play an effective role in a clear projection screen and excellent daylight viewing experience. Even the best projector can meet your requirements to project in sunlight rooms. Watching movies and favorite content in the daylight has become easier for you with an outdoor projector of 3000 lumen brightness. Consequently, choose a projector that produces high brightness. Good Luck

Frequently Asked Questions

How many lumens can damage your eyes?

There is no specific value; it depends on the environment and your eyes. If you are using a high brightness projector in a dark environment, it can affect your eyes. Be careful while watching in too much light because it probably leads to eye issues.

How many lumens do you need?

Usually, the number of lumens you need depends on the location. A light of 10-20 lumens per square foot would be enough for a bedroom or sitting room. But you require lighting at around 60-80 lumens per square foot for a kitchen or room where a high level of light is needed.

How many lumens do you need for an outdoor projector?

Normally, an outdoor movie projector with a more advanced lumen brightness ranging from 2500 lumens to 3000 lumens would be suitable for outdoor setup. It would be best to consider buying a bright enough model to show sharp and crisp images in standard ambient light.

How do I make my projector bright in daylight?

Close your windows and blinds if they are open to boost your projector’s brightness. Direct sunlight will consistently detract the brightness of a projector, even over 4,000 lumens. Likewise, make sure to turn off the lights, mainly if they are bright enough to make it to the display.
