This tropical rainbow fish night light is made with a brass-plated laser-cut metal frame, and an epoxy resin fill. It comes with a 4-watt night light base and bulb. The base also has an on/off switch in case you take a trip and want to turn it off. It gives off just enough light to see where you are going at night and not wake you up. Also a very nice art piece in the day. It uses very minimal amounts of power.
