The Importance Of Light Bulb Lumen

Many people often misunderstand that when choosing a light bulb with a lot of brightness, you have to choose a high wattage bulb. In fact, the wattage of a light bulb is just a value that tells how much power the light bulb uses. Simply put, the more The wattage of the bulb is high even though it produces a very bright light output. But at the same time, it will consume more electricity, so you should check the brightness of the lumen (Lumen) together as well. So let's take a look together at what the light bulb brightness value is. How is it important? We also bring some simple basic calculation tips to help you save more electricity.

How important is light bulb brightness? Let's see.

Lamp brightness or lumens (LM) is a unit of measurement for the brightness of light emitted by a light bulb. It counts the total amount of light emitted by the light source. This will have a radius of 1 foot or 1 lumen per square foot. To make it easier to understand, it is in 1 square foot of that area. There will be 1 line of light or 1 lumen, and the higher the number of lumens, the brighter the brightness. Your bulbs will produce more brightness as well.

For example, if you purchase a 600 lumen light bulb, that means that the light line that will fall on your installation area will be 600 square feet.

Therefore, this brightness value is another important point that you should observe along with the wattage. Including considering the size of the room before choosing to buy. Because it will help you choose to use it in the appropriate area. Keeps your room from being too bright and hurting your eyes. Or not providing too little light that will cause you to perform various activities inconveniently.

Relationship between brightness and wattage

As mentioned above that when choosing a light bulb, you should check both the brightness value and the wattage together. To get the correct light value Suitable for use In addition, both values have a hidden relationship in terms of saving electricity. In order to choose a light bulb that helps save energy, you should choose High brightness but low wattage

Example

• LED light bulb brand A, brightness 2,520 lumens, wattage 20 watts, divide them together to get 2,520 ÷ 20 = 126 lumens/watt.
• LED light bulb brand B, brightness value 2,520 lumens, wattage 30 watts, divide them together to get 3,300 ÷ 20 = 84 lumens/watt.

When looking at it with the naked eye, many people would think that a brand B light bulb would definitely be brighter without calculations. But if you come by and see this article for a bit. We ask that you stop calculating by dividing brightness and wattage. From the results, you can see that Brand A, which you see has a low wattage value, produces up to 126 lumens of light per 1 watt, while Brand B, which has more power, But it gives only 84 lumens of light per 1 watt.

To make it easy to understand, Brand A uses less energy than Brand B and also has more brightness. For this reason, it helps you save electricity while still having enough brightness for use.

In the case if you are a person who does not like brightness, you can choose a low brightness value. But it is still necessary to choose a low wattage value as before. Because if you choose both brightness and high wattage values, Of course, this can increase your costs, especially for those who often use their lights for long periods of time or leave them on all night.
