Colour Temperature

The colour of the LED Lights is described by a term called “Colour Temperature”. It is measured in terms of Kelvin (K).  Though the term has the word temperature in it, it does not refer to the operating temperature of the light.  The colour temperature ranges from 0 to 10,000K. The lights are classified in the several ranges so as to understand the output light in a better way.  Colour temperature in the range from 1000K to 3000K are slightly yellowish in colour. As the temperature proceeds from 3000K towards 10,000K, it becomes white and then blueish.

The colour temperature that has to be chosen depends on the application for which the LED light is being used. 


The lights in this color temperature are better suited for decorative purposes and mild ambiance. 


LED Lights with a colour temperature of around 3000K are best suited for bedroom lighting as they are suitable to have a mild ambiance. 


Cool white LED lights which have a colour temperature of around 5000K are best suited for bathrooms and kitchens as they have provide good visibility. 


6500K is the daylight and LED lights providing such output are best suited for educational institutions, office applications and industrial shop floor. They best render the sunlight.
