A floodlight is a lighting fixture that specifies that the illumination on the illuminated surface is higher than the surrounding environment. Also known as a spotlight. Usually, it can aim in any direction and has a structure that is not affected by climate conditions. Mainly used for large-scale mining operations, building contours, sports stadiums, overpasses, monuments, parks, and flower beds. Therefore, almost all outdoor large area lighting fixtures can be regarded as floodlights. The angle of the output beam of a floodlight can be wide or narrow, with a range of 0 ° to 180 °. The beam with a particularly narrow angle is called a searchlight.
