The innovative smart coins 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 simple. The old light bulb is removed, the RGBW coin is connected tool-free using the quick clamps, inserted, and done! Depending on the mood, you can choose between daylight white, colored light, and various effects. A white diode additionally provides a cozy warm white light, making it unnecessary to mix a white tone from the colors red, green, and blue. The fixture is Zigbee-compatible. Zigbee is a wireless transmission protocol that connects devices from different manufacturers. This allows for centralized control of the lighting, which can also integrate roller shutters, heating systems, and alarm systems, for example. You can choose between controlling via a gateway of the same standard from other manufacturers or a Smart Home Zigbee remote control. Individual components can be targeted or switched in groups as lighting scenes.
