The Z-Bar Mini LED Lamp features the award-winning three-bar design for maximum reach and flexibility, Z-Bar® Mini is designed for smaller desks and work spaces. 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. Slide your finger along the touch strip to dim gradually, or touch the strip anywhere to jump directly to any brightness, including off. Warm or cool LED light options are available. Warm color temperature provides a light more like incandescent, a warm glow. Cool color temperature will create a whiter, almost blueish light.
