The most common question asked by projector users all around the globe is “how many lumens do you need to project in daylight? Well, no one can give an exact answer to this question however, we can provide you with the approximate range of lumens which you need only if you are keen on getting an answer to it.

You need lumens ranging from 2500-3600, in which 2500 being the minimum value required to project in the daylight while 3600 lumens is the recommended value.

Always keep in mind that this range is only for daylight viewing, not for the projection under direct sunlight. Since projection under direct sunlight requires a whopping value of 120,000 lumens of brightness, which is not possible for any projector to provide in today’s world. This factor has been discussed later in the article.

Before buying a projector, keep in mind the purpose for which you are buying the projector. We have prepared for you the list of the best projectors for daylight viewing, which might help you in your selection.

Key Factors To Consider:

If you want to know what are the factors which affect the performance of the projector in displaying projection during daytime and which you must consider before setting it up, go through the below-mentioned key factors.

1) Sunlight doesn’t fall directly

No projector till date can compete with the direct sunlight brightness as it requires almost 120,000 lux of brightness. So always make sure that sunlight is not falling directly on your projection screen, since it will make it impossible to project.

The rays from the sunlight will damage the projection, and it raises the temperature of the projection lens and ultimately results in damaging the inner body of the projector. So avoiding direct sunlight must be your priority.

2) Try to project with some shade in Room

Always try to project in a room having some shade. If there is any loophole, say that the projection surface is near the windows, then cover the windows with curtains for better projection.

3) Make the room dimmer as much as possible

If you don’t want to put too much pressure on your eyes, make sure to make your room as dim as you can. No matter where are you using it, either it is your office, house or classroom, this is a must-do thing for you to do. It will help you in keeping your eyes relaxed and prevents them from squinting.

If you have a projector that provides lumens ranging from 2500-3600, even a slight change in the percentage of dimming the room e.g. From 30% to 60% will have an unbelievable difference in the display brightness.

4) Is Projection On Wall Recommended?

Some people ask whether they can project on a wall or not? The answer to this question is “Yes”. But it is not recommended using your wall for projection. The reason for this is, no matter what the colour of your wall, even the white wall will cause the light to absorb rather than reflect it.

However, if you still insist on projecting on a wall, we recommend you paint the wall with projection paint. This will help you in getting a better display than before but still, that wouldn’t be what you are expecting.

5) Projecting in Daylight Using Projector Screen

As mentioned before, there is a huge hole in using the wall as a projection display since it doesn’t reflect as much as it absorbs.

Good projection requires good reflection which a wall is not able to provide. So using a dedicated projector screen is very helpful as it has high reflective surface components which make your projection look amazing. This lets you take full advantage of the lumens provided.

Therefore, it is always recommended using the projector screen instead of the wall to have a better projection.

6) Screen Gain Mechanism

The main mechanism with which the projector screen works is its screen gain mechanism. What it does is, improves the screen reflection value. For example, if the screen gain of your projection screen is 1.3x and the lumens brightness provided by your projector is 1300 lumens then it will increase the projected lumens brightness to 1690 lumens.

Therefore, if you are using a projector that is low in budget or is not too expensive, you are recommended to use the projector screen to see a visible difference.

7) Proper Projector Placement

Display size or screen size highly depends upon your projector placement. If it is placed too far it will result in a blurred or faded display, or if it is placed too close it will result in a small display size.

All of it depends on the throw ratios provided by the projectors. They come in different varieties ranging from short throw ratio, long-throw ratio and ultra-short-throw ratio.

Short throw projectors produce a 100″ screen display size from a distance of approximately 8-12 feet while on the other hand short throw projectors will provide the same size from the distance of just 2-3 feet. So having proper knowledge related to throw ratio is very important in getting a good and bright display.

8) Selection of Best Projectors for Daylight Viewing

Last but not least, the major contributing factor is the type of projector you use. Projectors are never always designed to use in bright rooms. We have provided you with the list of the best projectors for daylight viewing so that it can make your task easy.


So, the ideal lumens for projection in daylight is from 2500-3600 lumens, but it is not the only thing that matters. We tried our best to provide you with every little detail relevant to your question so that you know exactly what you want.

We hope that after reading this article thoroughly, you have a better understanding of your question, “how many lumens do you need to project in daylight?”.
