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's LED fixtures use a standard 12 volt transformer and are ready to use in any dollhouse electrical system.
This one is a black coach lamp. It is 1 1/2" tall in 1:12 scale.
