Correlated Color Temperature is the hue, or tint of white to expect from a light source and is measured in kelvin. Lower numbers give off a warmer white that is closer to candle light, and is good for relaxed and cozy spaces. Higher numbers give off a cooler white light that will appear more blueish. While values to the middle of the spectrum give off a more neutral or natural white light that is similar to daylight. Natural and cool white are considered ideal for task lighting.
