The Circula smart wall/ceiling light in anthracite impresses with its modern design and provides powerful illumination. Whether mounted on the wall or ceiling, the Circula helps you find your way in the dark and ensures greater safety. The Tunable Warm function offers a free choice of colour temperature within the warm light range. Using the Zigbee 3.0 function, the colour temperature can be adjusted between 2,200 Kelvin and 3,000 Kelvin. The lamp usually switches on automatically when it gets dark, at 20 per cent brightness and a colour temperature of 2,200 Kelvin. The solar light emits a warm, golden light (2,200 K) with a low blue component. According to studies, warm, long-wavelength light generally attracts fewer nocturnal insects than cool white light. The desired light colour and brightness can be individually adjusted via the app. As soon as someone approaches, the built-in motion detector switches the light to 100 per cent brightness and 3,000 Kelvin. After around 30 seconds, it reverts to the saved light colour and brightness. Zigbee 3.0 is a wireless communication protocol that connects devices from different manufacturers. Compatible with smart home gateways that feature a Zigbee 3.0 interface.
