Sister Light is a collection of rechargeable battery-powered cordless luminaires, consisting of table lamps, lamp with peg, and wall lamp. A "touch" control on the head allows switching on, dimming (4-step: 100%, 60%, 30%, 6%) and selecting the color temperature of the light (2700 K, 3150 K or 4000 K). It is suitable for both indoor and outdoor use and salt spray resistant (1500 h). An electronic control system monitors the remaining autonomy and ensures a constant luminous flux until the battery runs out. Recharging is therefore optimized and always properly done. The lamp comes with a USB Type-C cable for recharging; the battery charger is not included.
