Great condition lamp that I have owned over 10 years. Has several points of adjustment. Uses a standard 120 V bulb includes cord mounted dimmer switch by Lutron.
I don’t know the brand. It’s a copy of an Arco lamp that sells for thousands of dollars.
Has some scuffing on the brushed nickel finish shade. The finish is nickel with a clear coat. Redoing the clearcoat may be able to fix it but I’m not an expert.
The support arm can be separated from the marble base for easier moving.
