Color temperature is a parameter used to describe the colour of a light source and is usually expressed as a value in Kelvin (K for short). Lower colour temperatures (e.g. 2700K to 3000K) give a warm tone, similar to candlelight or the soft light of dusk, while higher colour temperatures (e.g. 5000K to 6500K) give a cool tone, similar to the bright light of day.

Color temperature plays an important role in the ambience and environment of interior lighting. Different colour temperatures of light can create very different atmospheres and moods. Warm tones give a warm and cosy feeling and are suitable for relaxing and unwinded areas such as bedrooms and living rooms, while cooler tones are more suitable for offices, commercial premises and other environments where clarity and brightness are required.

It is crucial to understand the importance of colour temperature when choosing indoor spotlights. Depending on the needs and scenario, choosing the right colour temperature can create the ideal lighting effect. Below, let’s take a look at the common colour temperature ranges and characteristics.

Common colour temperature ranges and characteristics

In interior lighting, common colour temperature ranges include warm, neutral and cool tones. Each colour temperature range has its own unique characteristics and applicable scenarios.

  • Warm tones (2700K to 3000K): Warm tones give a warm and intimate feel to the light and are suitable for use in domestic locations such as living rooms, bedrooms and dining rooms. This colour temperature creates a relaxing and cosy atmosphere.
  • Neutral tones (3500K to 4000K): Neutral tones of light are an intermediate colour temperature between warm and cool tones. Suitable for offices, study areas and commercial premises, this colour temperature provides bright and clear lighting.
  • Cool tones (5000K to 6500K): Cool tones give a refreshing and energetic feel to the light, similar to natural light. This colour temperature is suitable for use in environments where high levels of brightness and clarity are required, such as hospitals, supermarkets and offices.

After understanding the characteristics of the different colour temperature ranges and the applicable scenarios, let’s move on to some common colour temperature standards in artificial lighting.

Common colour temperature standards in artificial lighting include incandescent and daylight colour temperatures. Understanding these common colour temperatures can help us to choose the right light.

  • Incandescent colour temperature (approx. 2700K): Incandescent lamps are a common type of conventional lighting device, which usually have a colour temperature of around 2700K. Incandescent colour temperatures exhibit warm tones and are suitable for use in domestic lighting, such as living rooms and bedrooms.
  • Daylight colour temperature (approx. 5500K to 6500K): The daylight colour temperature is close to the colour temperature of natural light, showing a higher brightness and cooler tones. This colour temperature is suitable for use in environments where high brightness and clarity are required, such as offices and commercial premises.

Once we understand the common colour temperature standards, we can choose the right colour temperature for the needs of a particular scene. Below, I will provide you with some guidance on how to choose the right colour temperature.

How to choose the right colour temperature

There are several factors to consider when choosing the right colour temperature. Firstly, you need to consider the lighting requirements and the environment in which it will be used. Different places and activities may require different lighting effects. For example, bedrooms and living rooms usually require a warm and cosy lighting atmosphere, while offices and commercial premises need bright and clear lighting.

Next, consider the elements of the environment. Factors such as interior décor, wall colour and furniture can affect the reflection and presentation of light. Warmer colour temperatures can enhance a sense of warmth, while cooler colour temperatures can add vibrancy and brightness.

Depending on the needs of the space, I offer you the following guidance suggestions:

  • Living rooms and bedrooms: choose warm tones (2700K to 3000K) to create a warm and relaxing atmosphere.
  • Offices and business premises: choosing neutral tones of light (3500K to 4000K) will provide bright and clear lighting to help increase productivity.
  • Study areas and reading corners: choosing lights in neutral tones (3500K to 4000K) can provide clear illumination and reduce eye strain.
  • Kitchens and bathrooms: Choose neutral or slightly cooler shades of light (4000K to 5000K) that provide bright lighting and bring out the details of objects.
  • Commercial display areas and galleries: choose the right colour temperature for the items on display and the ambience required, with warm tones creating a sense of warmth and cool tones enhancing the brightness and contrast of the exhibits.

Finally, let’s explore techniques and options for adjusting colour temperature.
