The Shroom Lamp (4-Ring) features an industrial look. It was made with a piston from an airplane propeller. The piston has been high-polished to achieve a mirror finish. The 20-piece limited edition features hand-engraved numbering at the bottom of the lamp. Featuring an ultra-modern look, the lamp that measures approximately 9" tall will be an eye-catching accent in your home or office. It comes with a 60-watt bulb, cord, and a durable on and off switch.
