Lighting truss, also known as a lighting rig or light support system, is a specialized type of truss structure designed to support and position lighting fixtures used in concerts, events, theaters, and other performance spaces. These truss systems are typically made from lightweight aluminum or steel tubes with modular connectors that allow for easy assembly and disassembly. They can be configured in various shapes and sizes to suit the specific requirements of the performance or event. Lighting trusses can also be customized with additional attachments such as motors, clamps, or cables, which enable the precise positioning and movement of lighting fixtures during a performance.
