This ceiling light is available with a colour temperature of 2,700 Kelvin extra warm white, 3,000 Kelvin warm white or with dim to warm function. The version with dim to warm function imitates the dimming behaviour of classic incandescent lamps, which is perceived as pleasant. The light becomes darker when dimmed down and also changes its colour temperature. The colour temperature changes from 1,800 Kelvin extra warm white to 3,000 Kelvin warm white.
