The floodlight has the characteristics of wide illumination range, soft and uniform light, and other colors can be obtained by adding color filters. The floodlights used for stage lighting are generally designed as a row of lights for large area lighting. Lighting for local effects of the stage uses individual lamps with adjustable angles. The floodlights can't have spot and obvious mark of spot edge in the range of stage lighting.
