The LED supplementary wall and ceiling lamp (satellite) Q®-TETRA convinces with its modern design. The extension element of the master module can be used as often as desired. It is connected to the control module by a simple wiring. This wiring is carried out by means of cable ducts over the non-luminous sides. Thanks to the CCT light management, you can adjust the colour temperature from warm white to daylight white. You can also make the lamp shine in a color of over 16 million shades and save your setting via the memory function. This regulation is done via the supplied Q® remote control. All Q® lights can also be integrated into existing smart home systems based on the ZigBee wireless standard. The Echo Plus* and Echo Show (2nd Gen)* smart speakers already have an integrated Zigbee hub and can communicate directly with our Q® lights. For Echo Dot*, Echo*, Echo Spot*, Echo Show (1st Gen.) *, Google Home** and Google Home mini**, on the other hand, an additional gateway is required. With the connection to a ZigBee-compatible gateway of a third-party provider (e.B. homee etc.), the luminaires can be conveniently controlled via a smartphone, tablet or PC via an associated app. In combination with the Alexa* or Google Home** voice assistants, it is possible to operate the luminaires with voice control, so that phrases such as Alexa, turn on the light" will soon be a matter of course for you and increase your comfort and security in your home. *Amazon, Echo Plus and Alexa are trademarks of Amazon Europe S.a r.l and serve only as an indication of the compatibility and usage of our Smart Home Q lights.
