Balloon light tower led (also called lighting balloons) are a specialized type of luminaire used primarily for lighting in the motion picture industry, night highway construction, incident management, and public security applications such as police checkpoints. These luminaires typically consist of one or more high-intensity lamps surrounded by a translucent fabric balloon. The balloon acts as a diffuser to soften and disperse the light. The upper portion of the balloon sometimes has a reflective inner coating to direct more of the light downward. Some commercial products use a blower to expand the balloon, while others have an umbrella-like internal wire frame. The device is essentially an industrial version of a Japanese paper lantern.
