Made up of antique brass metals and brown marble, the Reader LED Desk Lamp presents a striking mix of industrial and mid-century designs. 360 lumens of strong, energy efficient LED task lighting is controlled by a sleek on/off touch switch on the base while the shade rotates side to side and up/down adding optimal adjustability. Charge up your smart device easily with a convenient USB port built right into the brown marble base. The LED lights are integrated into the lamp and are not replaceable, but last 50,000 hours.
