Definition of LED Colour Temperature:

ColourTemperature LED bulb colour temperature, measured in degrees Kelvin, determines the colour of an LED light bulb. It is the amount of red, yellow, blue and pure white light given off by the light bulb. This effect is often expressed as to how ‘warm’ or ‘cool’ the white light being produced is.

This concept can be simplified if you imagine the light given off from the sun at different times of day. At midday the light is at its brightest and whitest. At sunrise and sunset the light takes a yellower or more reddish tint. Thus, lower temperature LEDs have more yellow and higher colour temperatures are purer white.

LED Colour Temperature

The following boundaries should heed a better understanding of the various colour temperature definitions:

  • Warm White: typically from 2600 Kelvin to 3500 Kelvin
  • Natural White: typically from 4000 Kelvin to 4500 Kelvin
  • Daylight White: typically from 5000 Kelvin to 5500 Kelvin
  • Commercial or Cool White: typically above 6000 Kelvin
Name of White Comparable to a: Kelvin Colour Temperature
Warm White typical incandescent light bulb 2700-3500 Kelvin
Natural typical retail space with fluorescent lighting 4000-4500 Kelvin
Day/Daylight White used for high colour definition - typical noon day sun in many parts of the world 5000-6000 Kelvin
Cool/Commercial White used in many industrial and commercial applications like hospitals 6000-7000 Kelvin

Colour temperature is an aesthetic choice and you may have different preferences to match different applications. The following is a very general guide:

  • Warmer Whites are preferable in living and dining areas as well as reception areas to create a more relaxed environment.
  • Natural Whites are preferable for kitchens and bathrooms where tasks are performed.
  • Daylight Whites are favoured by retailers and offices, though natural whites could be utilised here also./li>
  • Cool Whites are found mainly in industrial and hospital areas.

Older eyes often react better in cooler colour temperatures. Women often prefer warmer colours than men. Task lighting is better if cooler. Cooler whites can raise attention/awareness. Warmer whites can soften environments and make for a more relaxed space. Warmer whites a more likely to mask the true colour of objects, adding a add yellow tint.
