This brass wall sconce with frosted plastic tulip shades illuminates thanks to a 3V lithium battery and an LED (light-emitting diode). Both are included with the sconce. You can expect the lithium battery to last approximately 50 hours, at which time you can replace it with the Lithium Battery Set. The LED is not replaceable, which isn't a problem because it will last approximately 4,000 hours. It is 1/12 scale, which is the most common scale for dollhouses and dollhouse miniatures. It means that if an object is 12 inches in real life, it is sized down to a one inch as a miniature.
Installing the sconce is easy--simply glue the metal back plate to your desired location, then attach the magnetized base of the light to the back plate. The innovative magnets are strong enough to hold the sconce, while also giving you the option to easily change the lithium battery and operate the sconce's on/off switch. It's form meets function at it's best!
