This is one of Clare-Bell Brass Works new LED dollhouse miniature lights. LED lights have a life of at least 50,000 hours and use a lot less power than incandescent bulbs. LED's give off almost no heat so are also safer for use in the dollhouse. LED lights can be intermixed with incandescent dollhouse fixtures. Clare-Bell LED fixtures use standard 12 volt transformers and are ready to install in any dollhouse electrical system.
This one is a brass 3 arm Hurricane chandelier. It is 1 1/2" wide x 1 1/2" tall in 1:12 scale.
