How to decide on the right colour temperature?

In our last blog we looked at the IP value of a lamp. Here we wrote that it is important to look at the protection that a lamp offers against dust and water. Another factor that you have to take into account is the light colour of a lamp. In this blog we tell you everything about different colour temperatures and which light colour best suits the different rooms at your home or at work.

The colour temperature of an LED lamp is indicated in the measuring unit Kelvin (K) on a scale of 1000 to 10.000. As the temperature of a lamp rises, the light changes from red to orange, to yellow, to white and finally to a blue-white colour. Low colour temperatures are therefore experienced as hot and high temperatures as cool.

Below a few everyday examples:

  • The glow of fire is about 2000K and therefore has a very warm light colour.
  • A sunset is about 4000K and has a cool white light colour.
  • An average sunny day is between 5000 and 5500K and has a cool light colour.
  • A cloudy winter day is around 7000K and is experienced as quite cool.

Which light colour do you need?

In our shop all lamps are divided into three categories: warm white, neutral white and daylight white. Below we describe each category and name a number of applications.

A lamp with a colour temperature between 2000 and 3000K gives a warm white colour. The warm character creates a calm, cozy and intimate atmosphere. Lighting in this category is ideal for the living room or the bedroom. In addition, we see that LED panels in this light colour are often used as shop lighting. The atmosphere-enhancing character lends itself perfectly for that.

Lamps with a neutral light colour fall between 3100 and 4500K. The colour can be described as clear and lively. A room where a neutral white light colour works well is the bathroom. This type of lighting is the most popular option as office lighting. The neutral light colour is perceived as the ideal sweet spot between on the one hand too hot and on the other hand too intense blue.

The category daylight white tends to be the most blue and falls between 4600 and 6500K. This light helps you to concentrate and keeps you alert. That is why lighting in this category is ideal for rooms where you need to be able to concentrate, such as your work room or your countertop lighting. This type of lighting is often used in situations where no daylight enters, such as a warehouse or workshop.

Office lighting

Above we looked at lighting for your home. Warm lighting is used for rooms where you want to create a cozy atmosphere, such as the living room or the bedroom. In a bathroom or office you use cooler lighting so that you can see everything clearly and work in a concentrated way. But which type of light colour is best used in the office? Productivity is very important and therefore several studies have been done into which colour temperature works best in an office situation.


Various studies have shown that our productivity is higher when we work under cooler lighting than under warm lighting. Other studies have shown that daylight offers various health benefits.

Researchers at the University of Greenwich found that employees who work under lighting with a high colour temperature are a lot more productive. The work performance increased due to an increase in mental acuity, vitality and alertness. In addition, the subjects became less tired and showed less sleepiness.

The reason for this is that blue light leads to the reduced production of melatonin. This fabric ensures that we become drowsy. Something that you obviously do not want in your workplace. We therefore advise you to use neutral white light or daylight at your office. Our Pro High Lumen LED panels are ideal for this. These come in different light colours:


“warm ““neutraal ““daglicht
Warm white 3000K Neutral white 4000K Daylight white 6400K

Note: avoid blue light in the bedroom. The reduced production of melatonin makes it difficult for you to fall asleep.

Programmed light: the future?

Just as the outside light changes during the day, you may also want to be able to adjust the lighting in your home or office. During the day you are at work and you need to concentrate. In the evening you want to be able to relax and it is important that your body produces melatonin.

Of course you can move from one room to another, but what if you could just change the light colour? At the moment this may sound like future music, but within one or two years, you will increasingly come across this kind of programmable lighting. How beautiful would it be if the lighting in a room automatically adjusts to your state of mind?
