You want to use the innovative Coins in combination with your existing lighting installations? No problem! If you have already installed recessed spotlights for standard lamps with a diameter of 51В mm, you can simply switch over to the super flat and energy-saving LED modules. The old lamp is removed, the tunable white coin connected with quick clips and you are ready to go! Use the tunable white function to set the light colour to suit your needs: from daylight white working light to relaxing, warm white lighting. The luminaire is Zigbee-compatible. Zigbee is a radio transmission protocol that links up the devices of several manufacturers. This allows not only the centralised control of lighting; shutters, heating and alarm systems, for example, can also be integrated. To operate the control, you can choose between the Smart Friends Box, a gateway for the same standard by a different manufacturer, or a Smart Home Zigbee hand-held transmitter. Individual components can be addressed, or switched on and off in groups as lighting scenarios.
