LED lights are a modern and energy-efficient way of lighting that offers many advantages. One of them is the possibility to choose the color temperature of the light, which has a great influence on the atmosphere and the well-being. But what is the color temperature actually and how can you choose it?

In this article you will learn everything you need to know about it.


What is the color temperature?

The color temperature is a measure of the light color of a light source and is given in Kelvin (K). The color temperature describes how warm or cold the light appears, and depends on the wavelength of the light. The shorter the wavelength, the higher the color temperature and the bluer the light. The longer the wavelength, the lower the color temperature and the redder the light.

The color temperature is not to be confused with the temperature in degrees Celsius, which indicates the heat of a light source. A high color temperature does not mean that the light source is hot, but that it emits cold light. Conversely, a low color temperature does not mean that the light source is cold, but that it emits warm light.

The color temperature is determined by a comparison with an idealized black body, which absorbs all incident rays and only emits thermal radiation. Depending on how hot this body is, the color of its radiation changes from red to yellow and white to blue. The color temperature corresponds to the temperature of the black body, whose radiation has the same color as the light source.

The color temperature of natural and artificial light sources can vary greatly. For example, sunlight has a color temperature between 2000 K and 6500 K depending on the time of day and weather conditions. A candle has a color temperature of about 1500 K, an incandescent bulb of about 2700 K, a halogen bulb of about 3000 K, a fluorescent lamp of about 4000 K and an LED lamp of about 2500 K to 8000 K.


How to choose the color temperature?

The choice of color temperature depends on various factors, such as the purpose, the room, the personal taste and the mood you want to create. The color temperature not only affects the appearance, but also the effect of the light on the eyes, the circadian rhythm and the emotions. Generally, warm light colors are cozy, relaxing and inviting, while cold light colors are activating, concentration-enhancing and factual.

To choose the right color temperature for your LED lights, you can follow these guidelines:

For living rooms such as living room, bedroom or dining room, warm light colors between 2500 K and 3000 K are recommended, which create a cozy and homely atmosphere. These light colors are also suitable for accent lighting of pictures, shelves or plants.

For work rooms such as kitchen, bathroom or office, neutral light colors between 3000 K and 4000 K are recommended, which enable a bright and clear lighting. These light colors are also suitable for general lighting of hallways, stairs or entrances.

For special applications such as industry, commerce or medicine, cold light colors from 4000 K are recommended, which offer a high color rendering and a high contrast effect. These light colors are also suitable for daylight simulation or plant lighting.

Conclusion

The color temperature is an important aspect when choosing LED lights, as it determines the light color and the light effect. The color temperature is given in Kelvin and describes how warm or cold the light appears. The lower the color temperature, the warmer and cozier the light. The higher the color temperature, the colder and brighter the light. The choice of color temperature depends on the purpose, the room, the personal taste and the mood you want to create.
