This ceiling light made of a brass base with a etched frosted globe illuminates thanks to a 3V lithium battery and and LED (light-emitting diode). Both are included with the lamp. 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 they 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 lamp 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 lamp, while also giving you the option to easily change the lithium battery and operate the lamp's on/off switch. It's form meets function at it's best!
