Colour Temperature Guide

What is Colour Temperature?

Colour temperature measures the colour of a light bulb and not the brightness. This is also used to indicate the 'coolness' and 'warmness' of a LED light source. 

Colour temperature is measured in degrees Kelvin and is a measure of the part of the colour spectrum that is found in light.
A simple way to think about this is to compare the light from the sun from sunrise to sunset. At noon the light is bright and white, even more so nearer the equator. At sunrise and sunset the light takes on a more yellow or even red tint. Lower colour temperatures will have more yellow, and higher colour temperatures will go from yellow, to pure white and eventually to bluish, like you might find on some of the blue tinted headlights on cars.

LED Lighting can produce a wide spectrum of Light, unlike their incandescent and halogen predecessors. However the two main types are Warm white (2750-3250k) and Cool white (6000k). Warm white resembles incandescent and halogen bulbs the closest.

 

What Colour Temperature do I need?


Choosing your Colour Temperature for your LED lighting is of personal preference for each setting and application. In general warm white is used for a more relaxed environment and cool white for working areas. Here is what we have generally found....

  • Cool White - Commercial properties, industry properties, retail outlets, offices, hospitals, kitchens, bathrooms, home study's
  • Warm White -Dining rooms, living areas, reception areas
