Abstract: A low-temperature theatrical lighting system consists of a rectangular frame structure having a pair of opposing tubular frame members; and a number of fluorescent lamps extending in parallel to each other between the frame members. Each frame member includes a number of fluorescent lamp sockets, and each fluorescent lamp is connected to an opposing pair of lamp sockets. The lighting system also includes a fluorescent lamp ballast assembly disposed within at least one of the frame members. The lamp ballast assembly is electrically connected to the lamp sockets and controls the intensity of light emitted from the fluorescent lamps.
