The Master LED wall and ceiling lamp Q®-TETRA convinces with its modern design. The control module can be connected to any number of expansion elements (satellites) by simple wiring. The wiring is carried out by means of cable ducts over the non-luminous sides of the light source. 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. These adjustments are made via the included 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.
