Wall lights are a great accessory to improve the lighting situation in any room, they’re highly practical and can be placed on any wall as recessed or simply attached lamps, they give a nice option to alternate between the lighting types in your home to change the shadows and geometry of your space and add ambience on their own.
Some smaller wall lights are also a great energy efficient light source when it’s not completely dark, to illuminate your working space or to provide you with a very subtle light source that doesn’t strain your eyes at night.
