The smart, innovative Base Coins with RGBW Zigbee control can also be used in combination with existing lighting installations. If recessed spotlights with a diameter of 51mm are already installed, switching to the economical LED modules is very easy. The old light source is removed and the RGBW Coin is inserted. The luminaires can now be controlled individually or together using an app, remote control or voice command: whether it's cosy dimmed warm white, functional bright daylight white or colourful colour gradients - the combination of Tunable White, RGB and dimming function offers countless possibilities. The LED Coins can be linked together more easily, are interchangeable and can be easily installed in shallow cavity depths.
