Colour Temperature
The color temperature of a lamp is measured in Kelvin. The lower the Kelvin value, the greater the red and yellow-shares in the light. It is therefore also called a warm white light. The higher the Kelvin value, the greater the blue components. This light is known as cool white light. In between, there is the area that is called natural white.
The manufacturing tolerances in the aforementioned luminous flux also affect the color temperature. The LEDs are therefore measured and classified by so-called binnings, after fabrication. A binning thus includes LEDs that have similar color temperature values. Especially when using multiple LEDs next to each other, it is therefore important to use uniform binnings.
