Floodlights can highlight the appearance of a building's outline, emphasize its different parts, and enhance the aesthetics and recognition of the building. In city squares, parks, amusement parks, zoos and other places, floodlights are used for lighting and decoration to enhance the artistic sense and aesthetic value of the environment. In exhibition halls, museums, art centers and other indoor places, floodlights are used to highlight the characteristics of exhibits, emphasize the colors and shapes of exhibits, and enhance the viewing experience.

Projection lamp is a lamp that designates the illumination on the illuminated surface to be higher than the surrounding environment. It is capable of aiming in any direction and has a structure that is not affected by weather conditions. The angle of the projected beam of a floodlight varies widely from 0° to 180°, and those with a particularly narrow beam are called searchlights. Floodlights, when projected from a height, provide a significant increase in the spatial brightness of the environment, with a large light coverage that gives a daytime-like appearance, and therefore a high quality of illumination and visual effect.
