A flood light is a large, powerful fixture that has a wide beam spread. It is a high-intensity artificial light that is used to illuminate a large area. Most often used outside, floodlights are found illuminating outdoor playing fields and sports events. Floodlights can also be used indoors for lighting stages to create an artificial daytime setting. When choosing a floodlight, significant features to look for are precise aiming, rugged exterior, and long life.
