"The color temperature of light sources is measured in Kelvin and is an important factor when choosing the right lighting. In this text we will deal with the term Kelvin and explain what it actually means."

The importance of Kelvin in terms of light and lights



What is Kelvin?


The Kelvin scale is one Unit to measurement the Color temperature From light. She is after the British physicist and engineer William Thomson, also known as lord Kelvinnamed, which revolutionized thermodynamics and temperature measurement in the 19th century.


Kelvin is a unit for measuring the thermodynamic temperaturethat is based on the absolute zero point scale, which is defined as the lowest theoretically possible temperature.


In contrast to the Celsius scale, which uses the freezer and boiling point of water as reference points, the Kelvin scale measures the energythe one of a object emitted becomes.


A higher Kelvin value means one higher Color temperature and one colder Light color.



The light color at lights - how much Kelvin for which living area?


The color temperature in the room measured in Kelvin (K) not only describes the light color of the attached lamp, but above all determines the prevailing atmosphere.


Whether it in Living area Most of the light color depends cozy and warm or factual and cool. With which Kelvin number you create which ambience and where rather warm white light and where, on the other hand, cold white light makes sense, we clarify these questions here in Blog Contribution.


"When choosing the right lighting, the light color plays an important role. However, it is important to note that the perception of the light color can be individually different and can therefore also play a role in the choice of light color."

How is Kelvin related to lamps?



The color temperature of light is influenced by different light sources, such as light bulbs, LED lamps and neon tubes. Each light source has a different color temperature, which is determined by its Kelvin value. For example, an incandescent lamp has a color temperature of around 2700 Kelvin and creates a warm, yellowish light, while an LED lamp with 5000 Kelvin creates a cool, bluish light.



Kelvin at s.luce


s.luce Pendant lights are not only an expression of style and design, they also ensure pleasant lighting in your home. The pendant lights of s.luce are known for fitting perfectly into different room concepts, be it in a modern living room, a kitchen or in a dining area. But not only the design is important, but also the light color, which is measured in Kelvin, plays a crucial role.


The Kelvin scale indicates how warm or cold the light of a lamp appears. As a rule, the Kelvin value for interior lighting is between 2700k and 6500k. A lower number of Kelvin creates a warmer, yellowish light that ensures cosiness, while a higher Kelvin number creates a cool, bluish light that is ideal for working. The lights of s.luce Almost all of them are equipped with an LED lamp - s.luce Luminaires are known for illuminating the living space with a pleasant color temperature of 2700 to 3000 Kelvin and thus perfectly in the spotlight. Also discover multiple pendant lights s.luce, illuminate your home with the perfect light color and highlight your air spaces perfectly.


s.luce Multiple pendant lights are a fantastic element for those who are looking for a unique and effective lighting solution. They consist of several lights that hang from a central point, often at different heights, to create an attractive and dynamic design. This type of lighting creates a strong visual interest and has the ability to mix a mixture of direct and indirect light into the room, which is both functional and aesthetically appealing. Another important aspect of s.luce Multiple pendant lights are that they are often equipped with LED lamps that create a light color of 3000 Kelvin.


Pleasant atmosphere: A light color of 3000 Kelvin creates a warm white light that is pleasant for the eye. It ensures a cozy and inviting atmosphere that is well suited for living areas.


Color rendering: This light color is close to the natural daylight color, which means that the colors in your room are represented realistically and alive. This is particularly important in rooms where colors and details are important, as in the kitchen or reading.


Energy efficiency: LED lamps with 3000 Kelvin are not only pleasant for the eye, but also energy-efficient. A daylight lamp consumes less electricity than traditional incandescent lamps and last longer, which is both environmentally friendly and cost -effective.


versatility: A light of 3000 Kelvin is a good balance between the warm and the cool spectrum. It is well suited for a variety of applications and rooms, from living and bedrooms to offices and kitchens. Overall, the combination of the visual interest of the s.luce Multiple pendant lights and the warm, inviting atmosphere that a 3000 Kelvin light offers, a fantastic lighting solution for every home.

Which light colors are there and where do I use which light color?



First of all, we want to give you a brief overview of which light colors there are and how much Kelvin has which color temperature. Here you differentiate between three light colors: Warm white, neutral white or universal white named and that daylight whitewhat often as cold white is called.


Light bulbs, for example, always release warm white light, whereas Led lamps are available in all three light colors.


Warm white Light includes the lower color temperatures between 2.700 and 3.300 Kelvin. Neutral white Light is then accurate between warm white and cold white from the Kelvin number 3.300 until 5.300 Kelvin and Cold white or daylight white has a color temperature of over 5.300 Kelvin.


Since our perception of a room depends heavily on the light color of the lighting, it is important that the right color temperature is also used in each room - otherwise it will quickly be uncomfortable in rooms in which we actually want to relax or the light is in other areas As in the study, not sober enough and makes us sleepy.


In living rooms like that Sleep - or living room as well as im Dining area , in which a particularly cozy atmosphere is desired, warm white light is recommended below 3,300 Kelvin.


It seems comfortable and, due to the rather yellowish to reddish color, reminds of the lighting mood during an initial sunset. A lamp in this Kelvin area radiates a very homely ambience, which is perfect for areas in which you relax or enjoy.


A rather universal or neutral white light color between 3,300 and 5,300 Kelvin, on the other hand, should be in Bathroom , the Kitchen or in study be used. It is no longer just to feel good, but the lighting must also support certain activities such as cooking, writing, reading, shaving or make -up.


The color temperature lies exactly between the very cozy reddish warm white and the rather bluish extremely sober daylight white and therefore looks factual, but not too cold - perfect for the home office area.


The extremely cool daylight with a color temperature of over 5,300 Kelvin is very rarely used in living rooms because it looks very sober and cold. In the cellar Or partly also in jobs. In the non -private area such as in factories or as Shop lighting On the other hand, such a light color occurs more often.

Overview of light colors and their area of ​​application.



Where which light color is suitable with which Kelvin number is ultimately dependent on our perception and can therefore also be different - there is no correct or wrong here. To give them the decision at the Illuminant To simplify choice for your lamp, we offer a clear guide again here:


Warm white light (2,700 to 3,300 Kelvin)


Cozy atmosphere for living and bedrooms as well as in the dining room


Neutral white light (3,300 to 5,300 Kelvin)


factual feel -good light in the bathroom, the kitchen and in the office


Daylight white light (over 5,300 Kelvin)


Very cool light for basement, the workplace or in the non -private area


Cold white light (over 6,500 Kelvin)


suitable for special applications such as in photography or in the industry 

Conclusion on light color-Kelvin



If you cannot choose or want to use your lamp for different activities, you can also use the so -called Dimm2 warm function, pay attention to the abbreviation CCT or simply use an LED lamp that can be flexibly adjusted in the light color. This makes it possible to convert a lamp of warm white to universal white or cold white.


Kelvin is an important unit for measuring the color temperature of light. Choosing the right color temperature for lamps can have a major impact on the mood and perception in one room. When buying lamps, it is therefore important to take the Kelvin value into account and choose the correct color temperature for the room
