ScreenBar is a revolutionary lighting system. Simply hang it on your monitor to light up your desk without taking up any valuable space. With automatic dimmer and asymmetric optical design, ScreenBar illuminates the working space with just USB power, avoiding reflectively glare off your computer screen. On the standard version, light sensors and buttons for operating the lamp are integrated in the thin lamp head. The plus version is designed with a desktop controller about the size of a coaster for faster lighting adjustment.
