Simple, yet elegant in design, the Dimmable-Bar LED Desk Lamp's slim, inverted-L-bar format features a 180 pivoting arm for angling the lamp head to achieve the perfect lighting zone. Depending on the specific situation at hand, you can also alter this lamp's color temperature & brightness level. Three adjustable temperature modes, with associated brightness intensities, allow you to tailor the lighting for resting, focusing or reading.
