Four-light square LED ceiling light Plain - controllable smart via ZigBee In this currently designed LED ceiling light, the four LED lights are framed by square metal elements in anthracite. This creates a visual demarcation that further accentuates Plain\'s bright glow. Plain can be switched in three stages as normal via the wall switch. However, it is also possible to control it conveniently via the smartphone using ZigBee (Alexa, Google Home). The light intensity and colour temperature can be adjusted continuously. The colour temperature can be changed from a soft warm white to cosy candlelight. Alternatively, the LED ceiling light Plain can also be controlled via a remote control (not included). - Very good colour rendering index - equipped with memory function The ceiling light Plain is handmade by the lighting manufacturer Bopp from Limbach in the Odenwald.
