LED wall washer lights are a type of LED lighting fixture designed to highlight architectural features, walls, and other vertical surfaces. They are typically used in commercial buildings, museums, and other large public spaces to create dramatic lighting effects.

The term "wall washer" refers to the fact that these lights project a broad, even beam of light that "washes" over a surface. This is achieved through the use of multiple LED bulbs arranged in a linear array within the fixture.

LED wall washer lights work by passing an electrical current through a semiconductor material, which produces light through a process called electroluminescence. In an LED fixture, the semiconductor material is typically a tiny chip of material called a diode.

LED wall washer lights differ from other types of LED lights in several ways. Firstly, they are designed to produce a broad, even beam of light, whereas other types of LED lights may produce a more focused beam or a diffuse light. Additionally, LED wall washer lights are often larger and more powerful than other types of LED fixtures, in order to create the dramatic lighting effects required for architectural illumination.

Finally, LED wall washer lights may also incorporate features such as color-changing capabilities and DMX control, which allow lighting designers to create dynamic and customizable lighting schemes for their projects.
