The ultra-flexible lamp with adjustable light color

Color Tune

Adapt light to mood and situation

Our Color Tune technology offers total flexibility and personalisation of light intensity and color, so you can separately adjust both the brightness and the warmth of your lamp light.

With a light color range from 3500 K to 2400 K, integrated Color Tune technology brings even more versatility to JOHN. A simple double tap on the lamp switch presents four different levels of light color and intensity – from a crisp light for daytime tasks to a softer glows for reading or bedside illumination.
