The importance of color temperature to home lighting is reflected in many aspects, including affecting visual comfort, affecting mental health, creating a different atmosphere, improving the quality of living, and meeting actual needs and preferences.
Whether you are a lighting designer or a user preparing to renovate your own house, you need to fully understand the choice and application of color temperature to create a beautiful and comfortable living environment.
This article will explain the difference between 2700K, 3000K, 4000K and 6000K color temperatures, and recommend the most suitable color temperature scheme for different application areas.
1. What is color temperature？
Before we learn how to choose a color temperature, what is the color temperature?
Color temperature is a scale that represents the light color of a source in Kelvin (K). It describes the color characteristics of the light emitted by the source, that is, the degree of warmth or coolness of the light.
The concept of color temperature is derived from the theory of blackbody radiation in physics, where when a black body (an object that absorbs all incoming light) is heated, it emits light, and as the temperature increases, the color of the light gradually changes from red to orange, yellow, white, and finally blue. Therefore, the color temperature is used to represent the temperature of the blackbody when the spectral composition of the light source is the same as the spectral composition of the blackbody radiation at a certain temperature.
Generally speaking, the lower the color temperature, the yellower the color, and the higher the color temperature, the whiter the color.
For example, when you see the light from a lighted tungsten lamp, this warmer yellow light corresponds to a color temperature of 2700K. The daylight you see in the afternoon, the color of this natural daylight is equivalent to 4000K color temperature.
The following can help you more easily understand the relationship between color and color:
2000K-2700K: Warm yellow (2700K light)
2700K-3000K: Warm white (3000K light)
3500K-4000K: Neutral white (4000K light)
5000K-6000K: Cold white (6000K light)
6500K-8000K: Cold white (daylight)
1.1. What is 2700K light？
The 2700K color temperature belongs to the low color temperature range, and the light emitted is warm yellow. This color temperature of light visually gives a warm, comfortable feeling, similar to the light color of dusk or candlelight.
Advantages of 2700K Lighting
The 2700K color temperature can create a warm, comfortable and romantic atmosphere, which helps to enhance people’s happiness. At the same time, it also has enhanced color expression, which will increase the color saturation of indoor ornaments, making the indoor environment more colorful.
Disadvantages of 2700K Lighting
2700K color temperature recognition is low, due to the yellow light, in the need for high concentration and clear vision of the occasion (such as reading, work, etc.), may not be suitable for use. At the same time, there is also a high energy consumption problem, although LED lamps have been significantly improved in terms of energy saving, but 2700K color temperature lights may need to consume more electricity when reaching the same brightness.
1.2. What is 3000K light？
The light at 3000K color temperature presents a warm white tone, and there are more red components, giving people a warm feeling. At the same time, because the light of this color temperature is closer to the color of natural light at dusk, it has a soft and comfortable visual effect.
Advantages of 3000K Lighting
3000K color temperature helps regulate the body’s biological clock, promote the secretion of melatonin, thereby improving the quality of sleep. At the same time, the 3000K light is more friendly to the eyes, reducing glare and visual fatigue.
Disadvantages of 3000K Lighting
The disadvantages of 3000K and 2700K color temperatures are similar, and the recognition is relatively low due to the warm light.This may affect reading and work efficiency to some extent. At the same time, it inevitably faces the problem of high energy consumption. To achieve the same brightness, 3000K color temperature lights need to consume more power.
1.3. What is 4000K light？
The 4000K color temperature of the light presents a natural white tone, similar to the natural light of the day or the shaded part of the daylight, giving a fresh, bright feeling.
Advantages of 4000K Lighting
The clear and bright 4000K color temperature is ideal for a variety of applications, especially those that emphasize detail and task orientation. The 4000K color temperature not only provides sufficient brightness to ensure that each of your operations can be performed accurately in the space requiring high brightness such as kitchens, bathrooms and home offices, but also promotes visual acuity, helping to improve your work efficiency and quality of life.
Disadvantages of 4000K Lighting
4000K color temperature is a relatively cold and calm feeling, which to a certain extent limits its application in some areas of the home. Specifically, for Spaces that prefer a warm, inviting atmosphere, such as a living room or bedroom, some people may find the tones of 4000K lighting too monotonous to meet the emotional needs of these areas.
1.4. What is 6000K light？
Light at a color temperature of 6000K presents a bluish white, that is, cold white, with high brightness and contrast. Can provide bright and clear lighting effect, make the details of the object more vivid.
Advantages of 6000K Lighting
The 6000K color temperature is particularly suitable for applications that require high levels of visibility and clarity, and the high brightness and contrast of the light helps people maintain greater concentration and efficiency while reading, working and studying.
Disadvantages of 6000K Lighting
Although the high brightness helps to improve work efficiency, due to its high blue component, long-term exposure to such light may still produce certain stimulation to the eyes, the eyes may feel dry, fatigue and discomfort, which is not conducive to the health of the eyes. Therefore, in the environment that needs to use the eye for a long time, the brightness and color temperature of the light should be properly adjusted.
At the same time, the 6000K color temperature is generally considered to be a more stimulating and cold light, which may give people a feeling of tension and discomfort. For people who are more sensitive to ambient light, this light may have a certain negative effect on mood and emotion.
2. Factors to consider when choosing different color temperatures
When you choose lighting with different color temperatures, you really need to consider a number of factors, including brightness, energy saving, emotional impact, eye health and sleep quality. Through a reasonable choice of color temperature, you can create a comfortable and practical lighting environment. Here’s a breakdown of these factors:
2.1. Brightness
Brightness refers to the luminous flux emitted by the light source, and lighting with different color temperatures has different brightness performance. Generally speaking, high color temperature (such as 6000K) lighting brightness is higher, suitable for places requiring high illumination; And low color temperature (such as 2700K) lighting is relatively soft, low brightness.
Select the appropriate brightness according to the specific use scenario. For example, in areas where fine work or reading is required, higher brightness lighting should be selected; In the rest or relaxation area, you can choose a lower brightness lighting.
2.2. Energy saving
Although LED lighting usually has a high energy efficiency. However, LED lighting with different color temperatures may differ slightly in energy conservation. To achieve the same brightness, low color temperature lights need to consume more power. So when you pay attention to the color temperature, you should also pay attention to the energy efficiency mark and power consumption of the lamp. Choosing lamps with high energy efficiency levels and moderate power can reduce energy consumption while ensuring lighting effects.
2.3. Emotional impact
Color temperature has a certain effect on people’s emotions and psychological states. Low color temperature (such as 3000K) lighting usually gives a warm, comfortable feeling, helping to create a relaxed and warm atmosphere; And high color temperature (such as 6000K) lighting is brighter and cooler, suitable for the need to focus and stay awake.
Choose the right color temperature according to the function and use of the space. For example, low color temperature lighting can be selected in places that need to create a warm atmosphere such as bedrooms or dining rooms; In places where you need to stay awake and focused, such as offices or study areas, you can choose high color temperature lighting.
2.4. Eye health
Color temperature also has an effect on eye health. Too low color temperature may cause the light to be yellow and dark, which is not conducive to the protection of vision; Too high a color temperature may produce too much blue light, causing damage to the retina.
It is recommended to choose lighting equipment with moderate color temperature and soft light to reduce irritation and damage to the eyes. At the same time, pay attention to maintaining proper lighting brightness and avoid looking directly at the light source for a long time.
2.5. Sleep quality
The quality of sleep is closely related to the color temperature of lighting. Low color temperature lighting helps to reduce the body’s excitement and promote the secretion of melatonin, which helps to improve sleep quality. High color temperature lighting may keep people awake and is not conducive to falling asleep.
It is recommended that in the rest area such as the bedroom, low color temperature lighting equipment should be selected to create a quiet and comfortable sleeping environment. At the same time, avoid using high color temperature lighting equipment before going to bed, so as not to affect the quality of sleep.
