The brightness of this wall lamp can be adjusted using a switch on the base. The knob adjusts the brightness of the light from 0 to 100%. The lampshade is height-adjustable, with the power cord wrapped around the wooden element. A black, cage-shaped lampshade hangs from a wooden beam, enclosing the bulb socket and wrapping the power cord around it. If the height isn't right, you can adjust the length of the wire to achieve the desired effect.
