"The Adler arc lamp brings the perfect complement to industrial and modern chic decor with its sleek style lines, rich materials, and monochrome design. Made of metal, the lamp features a slim stem leading to a sweeping arm that can be adjusted up and down and side to side to meet the needs of your space. To provide stability and add a touch of sophistication, the round base is crafted of marble. The stylish short drum shade - the focal point of the lamp - measures 18"" in diameter and is made of textured fabric. To softly distill the light from a 150W bulb, the shade includes a white diffuser. The base of the shade features an articulation point, allowing you to adjust and redirect the light wherever it's needed. Operated by a rotary switch located on the pole, the lamp is also powered by a 5' clear cord."
