Tunable White is a bathroom furniture lighting system based on the Human Centric Lighting concept and is guided by the human biorhythm. The light technology enables the automatic regulation of colour temperature and light intensity in the bathroom. Moreover, it can be controlled manually or via Bluetooth. Tunable White is programmed to emit warm-white light at night, medium-strong light in the morning and at dusk, and cold-white light during the day. Individual settings can also be made via an app.
