People are becoming more complex with the advancement in technology. While selecting a new projector with the required brightness levels, you may need clarification on the terminologies used for measuring brightness levels. For this purpose, you’ll need to learn the terminologies, how they are measured, and their purpose. Otherwise, there is a risk that you might need to buy the right projector for your home, school, or office. We are here to explain all the terminologies, including Lux VS Lumens Projector.
Units For Measurement Of Projector Brightness:
To better understand projector brightness, you must know all the terms used to describe it. The terms most commonly used are Lux, Lumens, and ANSI Lumens. All these terms are similar and possess various similarities, but they have some distinguishing factors as well.
Let’s explain these terms separately below:
What Is Lumens?
Lumen is referred to as the the total output of light produced whenever a source is turned on. It does not depend upon the distance of the source from the surface and thus it remains constant even if this distance is altered. Lumens in projectors are used to show the strength of light source.
What Is Lux?
Lux is the scientific unit for measuring the brightness of light as it is perceived by the human eye on the definite surface area. In lux the distance of the source plays a very important role. This is because brightness or the intensity of light decreases as the distance between the source and surface increases. But when it comes to projector, Lux is referred to as lumen per square area.
What Is ANSI Lumen?
Another term listed in any projector’s specifications is ANSI lumen. Here ANSI is the abbreviation for the American National Standard Units. It is a more accurate unit of light intensity than lumen or lux as it measures light input or luminous flux by referring to several other variables.
Now the point to be kept in mind is why certain projector companies use the term ANSI lumen instead of the lumen. This is mainly owing to its accuracy compared to the lumen, which is often inaccurate.
If We Compare Lux VS Lumens Projector: What Wins?
Lux and Lumens are similar but not identical. If we talk about Lux VS Lumens Projector, we can say that lumens are the quantity of light generated by the light source, but when we speak lux, they are changed according to the distance from the light source. In projectors, mostly lumens are mentioned as they are fixed for a similar light source to show its power.
Lumen Requirement Of Any Projector:
While addressing one of the most critical questions, i.e., Lux VS Lumens projector, another essential question comes to mind. This question is about the lumen requirement of any projector. So it is very significant to address this question as well.
In order to answer this question, one would need to know the purpose for which the projector is to be used once it is installed in the place of interest. In this regard, you need to consider the content to be projected, the light brightness of the surrounding, and last but not the least, the resolution of the projector.
1) Content To Be Projected:
If the user is buying the projector to set up a home theatre, then certainly a projector with a more significant number of lumen will be needed. But if you are purchasing a projector for use in offices for projecting presentations, a projector with a lower lumen number can also be brought.
To ease the process of buying the right projector, we have listed the number of lumens required in any projector and the content displayed.
Gaming: If the sole purpose of the projector is gaming, then 2000 lumens are required.
Home Theatre: The number of lumens required in a projector for setting up a home theatre is the same as that needed for gaming, i.e., 2000 lumens.
Office Use: If the projector is to be used solely for projecting presentations in an office setup, then the lumen number can be compromised to almost 1500 lumens.
2) Light Brightness Of The Surrounding:
Surrounding light plays a highly significant role in determining the number of lumens required while buying a projector. If the projector is to be used in a very dark room with little or no light, then the number of the lumen can be kept low. But if the ambient brightness is going to be high, you can never compromise on the lumen number.
3) Resolution Of The Projector:
If we want to find the answer to the question about the Lux VS Lumens projector, which is better, we must also consider the projector’s resolution. More excellent resolution is required for the gaming projector as well as those utilized for home theatres. Mostly projectors with a resolution of 1080p are used for these purposes. In the case of portable projectors, this resolution is reduced from almost 840 into 480p.
As we know that you are a projector user or a potential buyer, it is very important for you to understand all the specifications of projectors because every specification has a distinct value. In this article, the users are provided with a guide to understanding the basic concept of Lux, Lumens, and ANSI Lumen, along with the best choice among Lux VS Lumens projectors. These three terms are very important to understand the levels of brightness of a light source of the projector.
Finally, lumens are primarily mentioned in a projector’s specification because they are fixed for a light source and are not dependent on the distance of the light source. Lumens show the strength of the lamp to produce light. I hope this article is helpful to you. Best of luck!
What are Lux?
Lux is the measurement of light on a surface. Mainly it depends on the distance of light source from the object on which the light is observed?
What are the unites of brightness in projectors?
Lumens are the brightness units in projectors that show the strength of the light source in projectors.
