When it comes to lighting, many people have no idea what the difference is between lux and lumens. But if you really want to know something about lighting, it is important to understand the difference between lux and lumens. In this blog we explain the difference between lux and lumens in detail. All our lighting has its own lumen and lux values, including the biodynamic lighting that adjusts the light during the day to create more of an outdoor experience.

What is Lumen?

Lumen is a unit for luminous flux and is the most commonly used measure for measuring the intensity of light. The higher the value, the more light the lamp gives. The lumen value of a lamp therefore indicates how much light is produced. So if you want to buy a lamp that gives a lot of light, it is important that you know the size of the lumen value of the lamp.

In addition, it is important to know that the lumen value of a light source can differ depending on the color temperature. Lamps with a low color temperature can in some cases also have a lower lumen value. Of course, this also applies the other way around.

What is lux?

Lux is the amount of light that ultimately reaches the surface. This means that the higher the lux value, the more light falls on a certain surface. It is measured in lumens per square meter (lm/m³).

The amount of lux required depends on the activity that is carried out in the space. For example, for a living room, the perfect amount of lux would be lower than for an office space where a lot of reading and writing would be done. For lighting in a living room, between 200-300 lux is often recommended, while for an office space 500-1000 lux would be better.

Lux is also important for outdoor lighting. A parking lot needs more light than a park. As mentioned earlier, lighting is often tailored to the activities taking place in the space.

Lux is therefore an important factor because there are various lux standards that the lighting within a certain business space must meet. This helps to determine the appropriate lighting for a certain space within a company. It is important to have enough lighting to be able to carry out the desired activity and to meet the standards.

Where do the terms lux and lumen come from as measured values?

Lux and lumen are derived from the Latin words lux and lumen, which literally mean light and luminous flux. Lux and lumen are two different units that are used to measure the brightness of light. Lux is a unit for measuring light that falls on a surface, while lumen is a unit for the total amount of light that is given off by a fixture or lamp. Lux and lumen are often used in combination to assess the brightness of a light source.

What exactly is the difference between lux and lumen?

As previously described, the difference between lux and lumen is that lux measures the amount of light that actually reaches the surface, while lumen measures the luminous flux produced by a lamp. Lux therefore measures how much light falls on a surface, while lumen measures how much light the lamp produces.

Example of the differences between lux and lumen

The difference between lux and lumen can be difficult to understand, so here is an example. Imagine you have a lamp with a lumen value of 1000. This means that the lamp produces 1000 lumens. If this lamp is placed in a room with a surface area of ​​10 m², the lux value will be 100. This means that 100 lux falls on the surface. The formula is: Lux = Lumen/m³
