How Many Lumens Do You Need To Project In Daylight | 2023 Latest Guide

Are You curious about How Many Lumens Do You Need To Project In Daylight?

Projectors are amazing machines created by mankind and there is no doubt that there is plenty of thought process invested in it.

While the earliest form of projectors dates back to as old as 1659, there is surely plenty of development done ever since to cater to the needs of enthusiasts that want to watch their movies or perform tasks on a larger screen through the manipulation of rays.

Although we have come a long way in manipulating these so-called rays that are tweaked at a distinct wavelength at our will, there are still some drawbacks that might hinder our experience.

One of these hindrances is the ambient light from either an artificial stimulant or mother nature such as daylight and if you are searching for every nook and cranny to find the answer on how many Lumens do you need to project in daylight, then you might as well keep on reading because you are exactly where you should be.

Assuming you are not tech-savvy enough to understand these esoteric terminologies, it is in my best interest to shed some light ( No pun intended)  on how a projector works and what exactly is a Lumen intensity.

What is a lumen and what are its uses?

Proper knowledge about one thing leads to a better understanding of another. So, before moving on to the main topic, let us first understand what is a lumen. A lumen is defined as the unit of measurement for the amount of light that is emitted from a certain source. The word lumen is derived from the Latin word ‘lūmen’ which means light. In simpler terms, we can say that lumens are used to measure the brightness of a light source.

This unit is extremely important for projectors as the light output of a projector is usually measured in lumens. The amount of light output by a projector is one of the most important factors that need to be considered while choosing a projector. If you are looking for a projector for your home theater or want to use it in daylight, then you need to make sure that the projector you choose has a high-lumen output.

Now that we know what lumens are, let us move on to the main topic and understand How Many Lumens Do You Need To Project In Daylight.

How Many Lumens Do You Need To Project In Daylight

Now that you know a general understanding of how a projector works and what Lumens are. In order to get a decent projector setup in a brightly lit scenario such as daylight, you would be needing a lumen intensity of around 3000 to 5000 ratio. 

However, I would like you to know beforehand that the picture quality might not be as optimal as it would be in an ideal solution because ambient lighting highly disrupts the rays that are being thrown from a projector.

How can you calculate the number of lumens needed for your specific application?

There will be many times when you have to use your projector for different purposes. For example, you might want to use it for a business presentation in a brightly lit room or want to watch a movie in your home theater. The number of lumens required for each of these applications will be different.

In order to calculate the number of lumens required for your specific application, you need to consider two things:

– The screen size on which you will be projecting the image

– The level of ambient light in the room

Once you have considered these two factors, you can use the following formula to calculate the number of lumens required for your specific application.

For business presentations: (Screen size in inches) x (Room’s Lux level) / 1000 = Required Lumens

For home theaters: (Screen size in inches) x(Room’s Lux level) x 1.5 / 1000 = Required Lumens

For outdoor: (Screen size in inches) x (Room’s Lux level) x 3 / 1000 = Required Lumens

Here is a table for different situations and the recommended lumens:

SituationRecommended Lumens
Business Presentation in a Brightly Lit Room3500
Business Presentation in a Dimly Lit Room2500
Home Theater Use in a Darkened Room1000
Outdoor Use in Direct Sunlight3000

This table is just for reference and you should always use the formula to calculate the number of lumens required for your specific application.

4 Ways To Improve The Output Of A Projector In Daylight

1: Finding The Right Spot

You can still find workarounds like placing your projector in a place where the sunlight isn’t directly facing the lamp source or using the display screen where there is a sufficient amount of shadows present to prevent your images from looking washed.

To further improve the quality of your output, you can choose the right condition where the intensity of sunlight isn’t high enough such as cloudy weather because it can positively impact the reflection of light on the display screen, giving you much better results.

2: Choosing A Decent Reflective Screen

A reflective screen is another best solution to get the right amount of light rays reflected right back to the viewer’s eyes. You can choose either an off-white or grey color for your reflective screen which is big enough to repel any projections without compromising the results of your imagery or videography.

3: Investing In Laser-Based Projectors

LED or Halide-based projectors are fine and work quite well to meet the standards of the everyday consumer, however, if you have extra cash to invest to get a better edge when it comes to the quality and crispiness of your image, it is in your best interest to invest in a laser light source projector which is not only accurate in terms of color tone productions but also has super high Lumens intensity to withstand almost any ambient lighting.

4: Choosing Short Throw Projectors Over Standard Ones

Short-throw projectors are designed to be placed as close to the projector screen as possible because their throw ratio is extremely small which makes them extremely efficient when placed at the right angle because they produce super bright imagery with eye-popping colors without having high lumens aspect as their attributes.

However, they aren’t ideal for long-distance placement or bigger rooms because the rays emulated from its lens usually get scattered all over the place which makes the image looks stretched and downscaled.


Before we finish up let’s look at some common questions.

Q: What is the difference between lumens and brightness?

A: The difference between lumens and brightness is that lumens measure the amount of light output by a light source while brightness measures the level of intensity of the light. Lumens are usually used to measure the light output of a projector while brightness is a more general term that can be used to measure the light output of any light source.

Q: What is the difference between lumens and ANSI lumens?

A: ANSI lumen is a measure of the brightness of a projector that is calibrated to meet specific standards. Lumens, on the other hand, is a general measure of the light output of any light source. ANSI lumens are usually higher than lumens because they are measured under specific conditions.

Q: Do more lumens mean better projection?

A: Not necessarily. More lumens only mean that the projector is capable of producing more light. How well the projector performs will also depend on other factors such as the native resolution, contrast ratio, and throw ratio.

Q: What are some tips for projecting in daylight?

A: Some tips for projecting in daylight are to use a projector with a high-lumen output, use a screen with a high gain, and to block out as much light as possible. You can also use a projector with an auto-iris feature to further improve the image quality.

Q: Can I use a lower-lumen projector for my home theater?

A: Yes, you can. However, you might not be able to get the same level of image quality as you would with a higher-lumen projector.

Final Verdict

Working with projectors is usually fun, however, ambient lighting can get a little annoying because you cannot have dim-lit rooms available to you at all times to get optimal results. But fret not, because I have briefly answered how many lumens do you need to project in daylight.

Moreover, if you are still facing issues, you can read the above elements to tinker with your settings and placements to get better results while using your equipment in daylight for your everyday purposes.
