Cordless, rechargeable, battery lamp with a silicone stopper that can be inserted into a bottle to create an original light. A touch control on the top of the lamp head allows you to switch the light on, adjust its intensity and select its color temperature. And thanks to its high IP rating, the lamp can also be used outdoors. An electronic control system monitors and indicates the remaining battery power to ensure recharging is optimized and always performed correctly. The silicone (food safe) stopper fits into different bottle necks and can be easily removed, allowing the lamp to be recharged easily on its contact charging base. Battery charger not included. The Poldina Stopper can also be used with "Lido" ceramic bottles that can be purchased separately.
