Light temperature is measured in which unit?

Light temperature is measured in Kelvin (K), which is the correct answer. This unit is used to describe the color temperature of light sources, which affects how warm or cool the light appears. The Kelvin scale ranges from low values that correspond to warm, yellowish light (around 2000K to 3000K) to high values representing cool, bluish light (above 5000K).

Understanding light temperature in Kelvin is crucial for interior designers because it influences the mood and functionality of a space. For example, warmer light temperatures can create a cozy atmosphere, suitable for relaxation areas, while cooler temperatures are often utilized in workspaces to enhance focus and productivity.

Celsius and Fahrenheit are units of temperature measurement typically related to environmental temperature, not the color temperature of light. Watts, on the other hand, measure electrical power consumption and do not provide any information regarding the color or appearance of light.
