The innovative, smart coins 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 bulb is removed, the RGBW Coin connected with the help of the quick clamps, inserted and done! Depending on your mood, you can choose between daylight white, colored light and various effects. A white (W) diode also provides a homely, warm white light and eliminates the need to mix a white tone with the colors red, green and blue (RGB). The light is Zigbee compatible. Zigbee is a radio transmission protocol that connects devices from different manufacturers. This makes it possible to centrally control the lighting, into which, for example, roller shutters, heaters and alarm systems can be integrated. You can choose between operation via a gateway of the same standard from other manufacturers or a Smart Home Zigbee handheld transmitter. Individual components can be targeted or switched in groups as light scenes.
