High mast lights generally refer to a new type of lighting fixture composed of steel cone-shaped poles over 15 meters tall and high-power combined lighting frames. It consists of the lamp head, internal lighting electrical components, the pole body, and the foundation. The design of the lamp head can be customized according to customer requirements, surrounding environment, and lighting needs. The internal lighting is often composed of floodlights and spotlights, using NG400 high-pressure sodium lamps as the light source, with a lighting radius of up to 60 meters. The pole body is typically a pyramid-shaped monolithic structure, made from steel sheets, ranging in height from 15 to 40 meters, usually consisting of two to three sections.
