Z-Bar Desk Lamp features an award-winning three-bar design for ultimate reach and flexibility. The super-adjustable LED head can spin in its socket, sweep side to side, and rotate around the end of the arm to point in any direction. The touchstrip is located near the LED head for easy access. Slide your finger along the strip to dim gradually, or touch the strip anywhere to jump directly to any brightness, including off. The desk clamp allows users to maximize their work space by mounting the light to the edge of their desk. Compatible with optional occupancy sensor.
