The picture does not do this lamp justice! It is a stunningly beautiful piece! It can swivel 360° at the base and the arm has two twist-to-tighten brass knuckles that can articulate up and down. The metal lampshade twists side to side as well as up and down. There’s no position you can’t set this lamp at. The led is turned on and off by a turn switch on top of the shade. The led provides plenty of light to cover my workstation. I love this lamp!
