Adjustable wall lights must serve many functions, sometimes illuminating a whole room and other times spotlighting a specific place, reading area or work space. Most of these modern wall lighting fixtures thus use various types of adjustable swing arms that enable users to put the light exactly where it’s most needed. These wall lamps may use one, two or several bulbs. They also may be linear, spherical, geometric, industrial, neo-classical, contemporary, Mid-Century modern, or space age or Sputnik. Many adjustable wall lights include eco-friendly technologies such as sustainable materials and energy-efficient LEDs.
