I purchased this about a year ago, but I never installed it and just kept it in storage. After opening the box, I threw away the packing materials, so I stored it using newspaper. From the website: The "Groove" series has a very chic impression with the soft, moist light emitted by the spherical glass globe and the matching materials of brass and marble. The wall lamp is designed to hide the wiring and fixing screws, creating a sense of unity with the wall or ceiling, and is characterized by a sense of floating when the light is turned on. This series allows for total lighting coordination and is recommended for homes, hotels, and commercial facilities.
