What are Lumens?

Lumen describes the brightness (the amount or intensity) of light. Lumen is the count of the brightness of a light. It is the international unit of measurement of light. In scientific terms, a lumen is the measurement of luminous flux. It measures the amount of visible light emitted from a light source in a given time.
It is a standard scale for measuring brightness. Every light source, from fluorescent to LED, uses this scale. Hence, knowing recommended lumens per square foot is essential.
All this while, we have been measuring light with watts. Though correct, watt describes how much power a light source uses. It is a measure of energy. But, a lumen is the accurate measure of brightness. The light with a higher lumen will be brighter. Before lumens were standard, watts determined the power of a light source. Higher the watts, the higher the watt and brighter the bulb. Today, this calculation does not work. There are different kinds of lights in the market today. They have different energy needs. For instance, a LED bulb is energy-efficient compared to other bulbs of the same watt. It means that a LED uses less energy (watt) than its counterparts but gives more output. Watt cannot accurately measure brightness as bulbs are energy efficient. Hence, lumens are the correct measure to check the brightness of a light source.

Why do you need to have appropriate lumens for your space?

Lumens determine the amount of light needed to illuminate a space. Every space needs a different amount of lumens. Your lumen need depends on the size and intended use of the room.
But how do you determine how many lumens you need for an area? There are many factors that you should consider.

  • The size of the space plays a vital role in determining the lumen need.
  • What is the purpose of the room? What activity will take place there? Does the activity (cooking, sitting, or sleeping) need less or more light?
  • The taste of the owner/occupant also matters since they will choose the light source as per their taste.

The lumen of the light source in your space is very crucial. It affects a lot of things. It would be best if you had appropriate lumens in your area.

  • First, it controls the functionality and atmosphere of the area. If the space has few lumens, the lighting would be too dim, and adequate vision could be a hindrance. If there are too many lumens, the room will be too bright. It would make sitting in that area difficult for a long time.
  • The amount of lumens also gives the right aesthetic touch to your place. For example, if you need to highlight something with lights, you should use a bright light. You can set the mood of the area with lights.
  • Apart from functionality and vibe, they are essential for energy conservation. Using too many lumens for a compact space will lead to excessive energy consumption. It will also result in higher electricity costs. But if you use a bulb with too few lumens, you will have to use more light sources. It, too, will lead to more energy consumption and high electricity costs.

Hence, proper lumens ensure that the area is well-illuminated. The space is functional, energy-efficient, comfortable, and has the right vibe.
