In the lighting industry, color temperature refers to the perceived warmth or coolness of light emitted by a light source. It is measured in Kelvin (K) and helps determine the color appearance of the light. Lower color temperatures, such as 2700K-3000K, produce a warm and cozy yellowish light, resembling traditional incandescent bulbs. Higher color temperatures, such as 5000K, emit a cooler and bluish light, resembling daylight. Understanding color temperature is essential in selecting the right lighting to create the desired ambiance and aesthetic in various applications.
