"Sister Light Wi-Fi is a collection of battery-powered, portable, and rechargeable lamps that can also be controlled remotely using the Zafferano Lighting application. The collection includes table models (in two variants), wall, and stake models. A "touch" control on the top of the head allows for switching on, 4-step dimming, and selecting the light color temperature. With an IP65 protection index, they can also be used outdoors; they are also resistant to salt fog (1500 h). They have an electronic control system that monitors the remaining battery life and ensures a constant light output until the battery is exhausted, allowing for optimized recharges and always performing them correctly. All models charge by unscrewing the head and placing it on the contact charging base, included; the table models also charge by placing the lamp on the contact charging base. Charger not included."
