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
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 warmDIM 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 Colour Rendering Index of > 90 delivers a top colour spectrum, capturing the richness and subtleties of colours and textures with vibrancy and precision.
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 warmDIM.
JOHN comes with a USB-C connector and cable for easy and universal installation.
