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.
Color Tune
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.



Outstanding Light Quality
Uncompromising brilliance
JOHN’s high-performance LEDs and state-of-the-art optical lens beams beautiful, adaptable and de-glared light at maximum energy efficiency.
Outstanding Light Quality
Cutting-edge LEDs provide powerful illumination of 700 / 850 / 950 / 1000 Lumen at AA+ energy efficiency.

JOHN’s optical lens fragments and directs light to create an optimal, glare-free environment for reading and working.

With three taps on the smart switch, the lamp activates Warm Dim mode, automatically adjusting color temperature to brightness. Dim up and JOHN beams a crisp, bright light - ideal for daytime focus. Dim down, and the light softens to a gentle evening glow.

An outstanding Color Rendering Index of > 90 delivers a top color spectrum, capturing the richness and subtleties of colours and textures with vibrancy and precision.

JOHN is a masterpiece of Tobias Grau engineering, providing outstanding flexibility and quality of motion, so you can illuminate a chosen surface, object, or area with agility and precision.

JOHN is designed for ultimate ergonomic use, with effortless adjustment to desired light settings.
Intuitive Use
Our intuitive smart switch offers quick and easy adjustment through different light settings. Tap once to turn the lamp off or on. Hold to dim up or down. Tap twice to adapt light colour. Tap three times to activate Warm Dim.
