You’ve probably heard how how much light the sun emits, but how many lumens is the sun? You can work out how many lumens there are for any given brightness by using a formula that takes into account the distance between you and the object in question. This blog post will use photometric units of measure to help explain what a lumen is and how it relates to other aspects of our lives in comparison to how bright is the sun.
When people ask the question “How many Lumens is the Sun?”, it is often because they want to know how much light a lumen represents and as the sun is the brightest thing we know, we begin with that.
There are many types of lighting device, some types of lights include headlamps, flashlights, indoor lighting, outdoor lighting, LED lights and grow lights etc. The how many lumens is the sun question can be asked when talking about any of these light’s output as a way of comparison.
The amount of light that the sun produces is hard to measure. It has many different types of light, like radio waves and x-rays. But we can only measure the amount of visible light.
A lumen is a specific amount of visible light. The sun produces a lot of it, but we don’t know how much because it also has other types of light, electro-magnetic radiation, too.
Scientists have found out what it is like on Earth. They do this with ground-based telescopes, space shuttle missions, satellites, sounding rockets, high-altitude aircrafts and computer models. When they are finished measuring where the sun is in the sky at any given time of day for any given location on Earth’s surface, they know how bright it is that place.
That brightness of the sun on earth’s surface is called solar constant. It has a value of 1366 watts per square meter at the distance from Earth to where the sun shines brightest.
If you had a one meter by one meter solar panel that was 100% efficient standing perpendicular to the sun, it would produce 1,366 watts of energy. That is enough energy to power a blow dryer and dry your hair!
However, this is for the full spectrum of the sun. We are only concerned with visible light, so we need to adjust this number to account for only what the eye can see. The way to do that is either by solving an integration problem or just taking our word for it.
For our sun’s black body temperature of 5778 K, the answer is 93. For every watt our sun creates, it produces 93 lumens of visible light. So at earth’s orbit, each square meter will get 127,000 lumens from our sun!
So be warned – the sun is very bright and it will damage your eyes if you stare at it. You must take precautions and get sunglasses and sunscreen to protect your eyes and skin.
Now let’s find the area of a sphere that has a radius corresponding to earth’s distance from the sun. So with the radius equal to 92.96 million miles, one astronomical unit, or 149.6 billion meters, the area is 281,229,000,000,000 , 000 000 000 000 or 281.2 sextillion square meters. Now we just multiply that with 127 thousand lumens per square meter and we get 35 730 trillion trillion trillion lumens.
Our sun gives off a lot of light. It is a little brighter than the brightest head lamp. I don’t want to be the one buying the batteries for it because then they would wear out quickly. We could use rechargeable lithium ion batteries that are solar-powered!
A lumen is a unit (or measure) for how much light something emits in all directions at once, such as how much light comes from one candle or how much light an entire street lamp emits. The how many lumens is the sun? question can be asked when wanting to know how much light comes from a certain source.
In order to answer how bright the sun is, we need to work out how many lumens it emits using photometry units of measure. One way this could be done would be by measuring how bright one candle was and then multiplying that number by ten million (i.e., 10000000). It turns out that for every square meter on earth there are roughly 10000000 lumen coming down onto our planet’s surface! This means that even though you may think of yourself as standing in complete darkness during night time, your body actually sees more than 200000 lumen – how many lumens is the sun?
The how of how bright is the Sun depends on where you are on earth. If you were standing near one of Earth’s poles, then there would be no direct exposure to sunlight at all; how dark it was where you stood would depend upon how high the sun was in the sky (i.e., how close or far away it was). The opposite would also be true – if your location happened to be exactly underneath our planet’s equator during midday time, then not only will every square meter receive 10000000 lumen , but that light will also come down vertically! This means that everything around you under these conditions becomes extremely hot very quickly and could even damage living tissue due to overheating… how bright is the Sun.
how many lumens is the sun? The number of lumen that our Sun emits per square meter depends on where you are standing in relation to it. This means that if we were talking about how bright a car headlight or even how bright Earth’s full moon was, the answer would be:
Although things like headlights and flashlights can emit up to 2000 – 4000 lumens , sunlight produces much more than this when its beams shine down upon an area! In fact, depending on how far away from earth you are, how much surface area you are covering, how tall your body is and what time of day it is… if you were standing under the sun with all these variables in mind then light beams would be coming down upon every square meter of your being at 280 trillion lumen. This means that how bright is the Sun? It’s about 35 trillion times brighter than most flashlights!
