The Element Disc™ by Humanscale® uses innovative Thin Film LED Technology™, offering seven levels of brightness – from nightlight level to bright reading light—with just a pinch of the light head. It also features a sensor that turns the lamp on or off when someone enters or leaves the area. The optional power base includes a grounded power outlet and a USB 2.0 port. When you’re not using the Element Disc™, you can fold the lamp head onto the base to save space. Now that’s smart lighting.
