Lighting: Kelvin temperatures explained

The Kelvin temperature scale is a unit of measurement used to describe the colour temperature of light. It measures the hue of a specific light source and is expressed in units of Kelvins (K). Lower Kelvin temperatures, such as 2000K to 3000K, are considered warm and produce a yellow or orange hue, while higher Kelvin temperatures, such as 5000K to 6500K, are considered cool and produce a blue or white hue. When selecting lighting, it's important to choose a temperature that fits the desired ambiance and task. For example, warm lighting is often used in residential and hospitality settings, while cool lighting is more appropriate for office and commercial settings.
