Most white light is not pure white - it is actually tinted a little. Colour Temperature, or Correlated Colour Temperature (CCT) refers to the colour tint of a white light. Measured in the unit Kelvin (K), the spectrum of CCT indicates the many different shades of white light.
In the LED world, there are commonly 3 main colour temperature groups: 'warm white', 'natural white', and 'cool white'. Any colour on the spectrum ranging from 2000K-3000K is referred to as 'warm white', 'natural white' refers to colour temperatures between 3100K-4500K, and 'cool white' from 4600K-6500K. As these labels refer to a range of colours, it is best to check with your supplier, the exact CCT in order to obtain the colour temperature you desire.
The colours on the chart above are exaggerated - they are not actually depicting the primary colours red and blue, but simply show the tinted colours of white. Warm white colour is a white light with a yellowish tint (think of your halogen light bulbs). Cool white is a white with a bluish tint (think flourescent tube lights), and natural white is a colour somewhere in between the two.
In order to choose the right colour temperature for your needs, you can follow these general rules:
- Cool white - creates alertness and is suitable for working/task areas. Example: Offices, Garage
- Natural white - not too yellow and not too blue, natural white is suitable for everyday, general purpose use. Example: Living room, Kitchen
Warm white - Warm white tends to create a comfortable, relaxing feeling, and is less harsh on the eyes. This range of colour temperature is suitable for Bedrooms, Resturants
Now that you are an expert on colour temperatures, please consider our LED downlights range. Please note that most of the products on our website listed as 'warm white' refer to 3000K, 'natural white' refers to 4000K, and 'cool white' refers to 6000K.
