The Prism Inflatable Light (PIL) is characterized by a supporting structure in synthetic fabric and an air-inflated cylinder which raises the light source up to 4.5 meters (15 feet) high and provides excellent illumination over the area. The whole structure can be easily made to function by a single person in conditions of complete darkness in less than 3 minutes making it possible to illuminate areas up to 17000 sq. ft. (1900 sq. yd.).
