The inspiration for the lamp's name Sponge and the design language have been taken from mushrooms in the forest. The organic design and soft shapes make Sponge an incredibly elegant series that is suitable both indoors and outdoors. The built-in rechargeable battery makes it easy to take Sponge with you wherever you go. Adjust the brightness in three steps to create the perfect atmosphere. The battery life is up to five hours at full power and even longer if the light is dimmed down to mood lighting. You easily charge the battery by placing the lamp on the included charging station.
