The Amble Performance desk lamp with USB lets you charge your phone, tablet and other mobile devices at your desktop. When the tri-position base is moved from one point to the next, it changes light settings and the gravity driven shade that surrounds the LED automatically tilts and falls into place eliminating any glares. It has a built in occupancy sensor and you can press and hold the power button to change the intensity of the lighting. It can be ordered in different colors and comes with a 15 year structural warranty and a 1 year warranty on the LED/Transformer.
