A power-packed duo: Qi-wireless charging and next generation ClearSun LED lighting. The Power Up LED Desk Lamp features BOTH giving you the total convenience of wireless charging and dramatically reduced eyestrain. Three out of four people experience the discomfort of eyestrain on a daily basis. Harsh illumination, blue wavelength spikes and computer screens are often the culprit. OttLite ClearSun LEDs provide a balanced spectrum – just like the sun – to make seeing and reading easier and more comfortable. This powerful illumination is delivered in a sleek and flexible style with touch controls and dimmability to customize light levels. Charge your Qi-enabled device wirelessly on the lamp base or through the 5V, 2.1A USB port.
