The inner design high-tech waterpower device, no need for the battery, it will light up when the water flows. And it will light off immediately when the water stops. Although there is no electricity, it will light up with hydro power. It is a kind of environmental product. It won't lose any electric though it is waterpower. The DC current is only around 3,5V, the water flows and the wires system are separated.
