A major benefit of LED lighting technology is the ability to create and control the colour temperature of the light during the production process.
Colour temperature is measured in Kelvin, which gives an indication to the visual appearance of the light given by the luminaire, albeit a shade of white. The higher the Kelvin (or CCT), the more intense the lumen output. A luminaire and colour temperature should be chosen with its application in mind. Lower Kelvin temperatures are usually a warm colour, such as warm or natural white whereas higher temperatures (5000 kelvin and above) are cooler colours, such as a pure or warm white. But what colour temperature should you be using for your applications?
Warm White which is around a 2800-3000 Kelvin temperature is generally used in living spaces to create a relaxing atmosphere. Commonly seen around the home in living rooms and bedrooms:
Natural White which is around a 4000-4500 Kelvin temperature is seen in both domestic and commercial LED lighting applications. Commonly used for lighting areas like kitchens and offices.
Pure White which is around a 5500 – 600 Kelvin temperature and if often employed when a crisp, high quality of light is required for task areas. They are regularly seen in offices, work stations and in retail where product appearance can be enhanced by a fine quality of light.
Cool White which is around a 6500 – 7000 Kelvin temperature with a cool/blue tint. As it is 10% brighter than warm white counterparts it is often employed when maximum lumen output is required, so is commonly seen in use for exterior or industrial applications such as warehouse lighting.
