Step 4. What is colour temperature? (kelvins)
Colour temperature is the appearance of light which the light bulb radiates. You have guessed it, different bulbs radiate different colour temperatures. In LED lighting there are three basic choices of light bulbs, all of which are suitable for different rooms - warm white, cool white and daylight. Each one produces a slightly different colour. The look and feel of a room is hugely influenced by its colour temperature. This temperature is expressed in Kelvins. Based on a Kelvin numbered scale, the higher the colour temperature, the cooler, more natural light will be imitated. A lower number on the Kelvin scale will provide a softer, warmer, more relaxing glow.
