This is a 1" scale battery operated ceiling light with a clear shade. The light is equipped with a LED bulb and runs on a long lasting changeable 3 V lithium battery that is hidden in the base. Measures approx. 1-1/8" in diameter and 1"T. New style bulb has a nice soft warm glow and is equipped with a magnet and an extra battery for your convenience. We recommend gluing the magnet to the wall for better adhesion support.
