What is Wall Wash Lighting

Wall wash lighting is a technique used to evenly illuminate a vertical surface, such as a wall, by casting a wide beam of light onto it. The purpose of wall wash lighting is to eliminate shadows and create a smooth and uniform appearance on the surface being illuminated. This technique is achieved by strategically placing light fixtures, known as wall washers, at a distance from the wall and directing the light beam at a wide angle.

By positioning the fixtures at a specific distance, typically around 2.5 to 3 feet away from the wall, and angling the light beam towards the surface, wall wash lighting ensures that the entire vertical space is evenly lit. This eliminates any dark spots or uneven lighting, creating a visually appealing and uniform illumination.

Wall wash lighting is commonly used in various settings, such as art galleries, museums, or even in residential spaces, where the goal is to highlight and enhance the visual impact of a vertical surface. It is particularly effective in showcasing artwork, architectural features, or decorative elements on a wall, as it provides a soft and diffused light that enhances the texture and smoothness of the surface.
