How Many Lumens is the Sun? Different Light Type Explained

How Many Lumens is the Sun

The intensity of Sunlight | Measure with Lumen: Counting Lumen is important in our everyday life. Although, we don’t really do it pretty often. But, it does have a great impact on many tools and factors. Think about it, if you are lying on a beach and the intensity of sunlight is more than usual, then what will happen? It can heavily affect your skin. It also raises the question, how many lumens is the sun and how much is suitable for the human body.

On the other hand, we use different types of light in regular usage. Every light has a lumen value to describe its intensity and vision area. If the amount is much higher than the recommended range, then it can have a negative effect on our eyes. Every light has such a lumen count, and we should learn about them beforehand. Let’s talk about them more elaborately.


The first thing you have to know is what lumen means. In simple terms, a Lumen is a unit. It also shows as “lm” in the short form. The amount of visible light radiates from a source per second or time unit. It has a direct relation to lux, which indicates the lumen rate per square meter. Well, it is the basic scientific introduction of the lumen.

Different types of lamps generate light depending on the lumen count that goes from 200-4000 depending on the incandescent light build quality. As a reminder, incandescent means the bulb or light that is covered with glass protection and generates light through a heated wire. Usually, they are filled with inert gas or empty to prevent oxidization. As we all know, Sun is the only natural source of light.

There are different types of lumen units available. As an example, ANSI lumen and Peak lumen. They are used to measure different projector’s light amounts. ANSI lumen is used for regular projectors, where peak lumen is used for CRT projectors. Let’s talk more about the lumen. You will learn about how many lumens is the sun along with different light types. Often people use Candle to measure light as well. So, how many lumens is a candle? 1 candle equals 12.57lumens.

There is a long-distance lying between the Sun and Earth. There are also a lot of gas layers and gravitational field layers available in between them. So, no matter how much lumen the Sun produces, only a small portion of it finally hits the earth.

Researches show that Sun produces 93 lumens per watt of energy for visible light. For every square meter, it produces 127,000 lumens. Considering the total area of the Sun, it generates around 35.73 octillion lumens. So, how many candelas is the sun? You just have to divide the number by 12.57.

Although, a slight portion of it actually comes to earth. Still, it is bright enough to burn our eyes with a little longer look. That’s a crazy amount for sure. It shows just how bright is the sun.





While talking about lumen, it is necessary to learn about its measurement depending on the sunlight. As we mentioned, Sun is the only natural source of light. Sunlight is electromagnetic radiation that comes off because of the massive heat produced by the Sun. Sunlight contains many types of light, like visible and invisible. Among visible lights, there are 7 known variants. We know them by their visible nature, and they are pretty known to us. Violet, Blue, Red, Green, Yellow, Indigo, and Orange. We also count White and Black as two other visible lights. A mixture is also possible among these visible lights to create a hybrid one. But, they do exist within the wavelength range from 380-700 nanometers.

There are other types of light like infrared, ultraviolet, cosmic, and more. They are not visible in human eyes and have a much lower or higher wavelength. Not to mention, they are pretty reactive and capable of causing certain effects on any living body. Although there are many lab-made modifications to use them, and we are pretty familiar use many UV and X-ray light usage.

The average light falls 164 watts per square meter. As we know, sunlight is essential for living beings. So, the rate and filtration are pretty important. Apart from all this information, the most important one is the lumen count. As we are talking about lumen, let’s have a good look at how many lumens is the sun and how sunlight helps us. We will also describe different light particles with detailed information.

Different Light Type

Here, we are going to talk about different types of light. Sunlight comes as a combination of various lights. We will try to describe them individually to get a proper idea about them. You may already know some of them. Let’s get some detailed information below.

Visible Light

As we already mentioned, visible light has a range from 380-700 nm. There are only 7 light and a mixture of them within this range. They do not have a negative effect on the living body. Although, some different creatures have different physical attributes and reactions to light. Some of them can handle other lights as well. Blue, Green, Red, Orange, Yellow, Violet, and Indigo are the seven visible lights. You can get their wavelength from the wiki.

Ultraviolet Ray

Sun is having constant nuclear fusion that also makes it producing UV rays. It usually has a lower wavelength than visible light that goes from 100-400 nm. There are many types of it as well. Basically, there are 3 types. Ultraviolet A, B, and C. UV A is the lowest effective UV of the types. It has a wavelength range from 315-400 nm. On the other hand, UV B has 280-315 nm, and UV C has 100-280 nm. All of them are capable of causing minor to high cancer, disease, or permanent physical failure.


Infrared rays have a high wavelength that can go from 700-3000 nm and more.  It has 3 types that are known as A, B, and C. Type A goes 700-1400 nm, Type B is 1400-3000 nm, and Type C is 3000 nm – 1 mm.

Final Word: How Many Lumens is the Sun?

As you have already learned, Lumen is a unit to measure all types of light. Although, the usual measurement is appropriate for visible lights. Other forms of light use more complicated units. As a reminder, we have discussed sunlight, how many lumens is the sun can produce, many types of light along with their wavelengths. As we have mentioned, the sun produces a large amount of light every second. Their intensity is way too high. Measuring the quantity with lumen is pretty hard well. It is pretty much over the chart. But, you can get a proper assumption over the statistics.
