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 51 mm are already installed, switching to the energy-efficient LED modules is very easy. The old light bulb is removed, the RGBW Coin is connected using the quick connectors, inserted, and done! Now the lights can be controlled individually or collectively via app, remote control, or voice command: whether it's cozy dimmed warm white, bright daylight white, or colorful gradients - the combination of Tunable White, RGB, and dimming function offers countless possibilities. The LED Coins can be easily linked together, are interchangeable, and can be installed well in shallow cavities.
