What is lumen in projector

A solid connection exists between the lumen and the quality of the image exhibited by a projector. On this platform, we will try exploring every bit of information on lumens and what significance they carry while projecting an image on the screen.

Lumens are officially and formally called ANSI lumens. In addition, this measurement shows how strong and intense a light source will be! You must understand this terminology beforehand while buying a projector for your business or home needs.

Lumens in Projectors- The basic overview

Lumen is the measurement of brightness. At times, you might have heard about this terminology with the term “ANSI lumens.” For the information, ANSI is abbreviated as American National Standards Institute.

There are different lumen counts for different light sources. Like a candle has 14 lumens, a 100-watt light bulb contains 1600 lumens. On the other hand, sunset shows 400 lumens, and fluorescent lighting exhibits 400 lumens.

Projectors generally carry three light sources, including LED, lamp, and laser. Those planning to invest in the lamp projectors must know that their appliances will show at least 2000 lumens. And the laser projector contains 3500 lumens. Rest, the LED projectors stay above 2000 lumens.

LED projectors seem to be a suitable pick from those mentioned above three light sources. They possess improved and enhanced color saturation and manage to show maximum luminous efficiency.

Why do lumens matter in a projector?

The significance of lumens in a projector should not be disregarded at all. There exist a clear-cut relationship between lumens, brightness, image size and quality, color, and lighting.

When picking a projector, you must check how much bright and quality image it gives out! This can be determined by knowing about its lumens rating. It is a crucial reference point that will help you choose the right model.

If you wish to experience ambient lighting, it is recommended to get a projector that accompanies higher lumens, like up to 3000 lumens. This will help you get better results and excellent image quality.

For those who want to watch movies without ambient lighting on a projector, then approximately 2000 lumens are enough and not more than that. Such a lumen rating gives ideal brightness, a clear image, and no distorted and blurry quality.

The recommended lumen rating for outdoor projectors

Outdoor projectors with a 500 lumens rating seem to be the most appropriate rating. They work perfectly in low light conditions, and you can even utilize them as indoor projectors.

Cheap and low-quality outdoor projectors exhibit 200 to 300 lumens that fail to give high-quality images both day and night. Thus, a 500-lumen rating is recommended to get a great and most satisfactory cinematic experience while having outdoor movie time.

The recommended lumen rating for Home Projectors

When choosing a projector for your home, it is suggested to choose the model rated below 3000 ANSI lumens. This respective rating will be able to project and perfectly display the 80” picture. It brings minimal distortion and no blurriness. Thus, you will get a better color performance at this brightness level. The only drawback is that you have to regulate and keep on reducing the ambient light.

The suggested lumens for projectors utilized for business and education purposes

You can have a projector for small-scale meeting rooms or classrooms that displays 3000 to 3999 ANSI lumens. Such a setting can ideally project the image and is extremely suitable for 80″+ screen size.

Try looking for a projector that possesses 4000 to 4999 ANSI lumens for mid-sized conference rooms. It is assured that you will get high-quality images with such brightness, and you do not have to worry about controlling and reducing the ambient light.

Lastly, the recommended brightness level is 5000+ ANSI lumens for large-sized meeting rooms and classrooms. Here you get a 100”+ picture size. Such projectors are ideal for exhibition halls and auditoriums. Their performance does not get affected by the high levels of ambient light.

Is there a relation between high lumens and 100% image quality?

You might be wondering, is there a relation between high lumens and assurance of getting 100% image quality? Here we will break down this concept!

It does not necessarily mean that the more the lumens, the more fine image quality you will get! Experts have advised investing in the model, which shows balance lumen rating, appropriate brightness, and contrast ration effect. You should not rely only on the number of lumens. Thus, pick a projector that promises to display the clearest images, the best color performance, and desired contrast ratio effect.

Though lumens determine brightness and image quality, you must also consider the light processing mechanism of the projection lamp and color wheel. The projection lamp decides the brightness output. On the other hand, the color wheel controls and regulates color performance.

Which factors affect the projector brightness apart from lumens?

Ambient light and screen size impact and influence the projector’s brightness.

Ambient light

When the ambient light is uncontrolled, the image quality is ruined and destroyed. If your room already has lots of lighting, you must invest in a higher brightness projector. You can have the projector for darker spaced rooms, which offers a lower brightness. The recommended lumen range is 2000 – 4000 lumens.

Screen size

The larger the screen size, the higher the brightness is! If you consistently want to get high-quality images from the projector, it is advisable to choose a large screen size model.


We hope you have now understood the lumen terminology directly related to the projector brightness. 

The lumen rating determines how bright, rich and clear the projector will produce the image. There are different lumen ratings for projectors meant for outdoor/indoor, business, and educative purposes.

For example, projectors for outdoor settings and large rooms need a high lumen count. Rest, choosing a projector with fewer lumens is suggested if you want to use it in a setting where ambient light can be reduced and controlled. Stay tuned and connected!
