Color temperature refers to the warmth or coolness of light, measured in degrees Kelvin (K). It helps describe how a light source appears to the human eye. Lower values, like 2700K, produce a warm, yellowish light, similar to that of a candle or incandescent bulb. Higher values, such as 6500K, emit a cooler, bluish light, resembling daylight. Different environments and activities benefit from specific color temperatures. For instance, warm light is often used in homes for a cozy atmosphere, while cooler light is preferred in offices for better focus and productivity. Understanding color temperature can enhance both comfort and functionality in lighting design.
