The smart wall/ceiling luminaire Circula in white features a modern design and brightly illuminates your entrance area. Whether on the wall or the ceiling, Circula helps you find your way after dark and provides increased safety. The Tunable Warm function offers free choice of colour temperature in the warm light range. The colour temperature can be set between 2,200 Kelvin and 3,000 Kelvin using the Zigbee 3.0 function. In the basic setting, the luminaire switches on when it gets dark with 20% brightness and 2,200 Kelvin thanks to the integrated dusk sensor. The desired light colour and brightness can be individually adjusted using an app. When someone approaches, the outdoor light is switched to 100% brightness and 3,000 Kelvin by the built-in motion sensor. After about 30 seconds, the system switches back to the saved light colour and brightness. 2,200 Kelvin lies outside the visible range for most insects, so they are not attracted by the additional light source, making the luminaire particularly insect-friendly. Zigbee 3.0 is a radio transmission protocol that interlinks devices from different manufacturers. Compatible with Smart Home Gateways featuring a Zigbee 3.0 interface.
