Autarkic and smart controllable - LED solar-powered exterior wall light Yoko The Yoko LED outdoor wall light can be installed anywhere outdoors, independent of a power connection, because it is powered by sunlight via the integrated solar panel and an integrated lithium-ion battery. But the ZigBee-compatible outdoor wall light has even more to offer: It can be coupled with a smart home system with ZigBee interface for voice or app control, can be controlled via the integrated sensor or with an optional ZigBee remote control. When the lamp is pointed towards the sun, the battery of the lamp is fully charged within 6 to 8 hours and then guarantees a lighting duration of 8 to 10 hours.
