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. A through-table mount allows users to free up desk space. Compatible with optional occupancy sensor.
