Crafted from steel and curved glass. We recommend our LED Candelabra E12 bulbs (6610071B134), sold separately. Can be mounted on a vaulted ceiling. Professional installation required. Chandeliers weighing more than 50 lbs. cannot be mounted alone to a standard outlet box and require additional bracing above the ceiling where they are to be installed. In order to protect the delicate glass of this collection, some assembly upon delivery to your home will be required.
