A high mast light is an area lighting system that is raised high to minimize ground level obstructions and create uniform illumination across a large area. Throwing a controlled flood of light from above 15 meters (18 m – 55 m typically), high mast lighting systems are the functional extension of public lighting infrastructure which provides area and road illumination at pedestrian, urban or vehicle scale from below or at a height of 15 meters. The high mounting height combined with a multiple-luminaire configuration makes high mast lighting the most efficient and effective way of illuminating large areas. High mast lights are also the most heavy duty lighting systems that must possess the strength and resistance required to survive the most challenging outdoor environments.
