High-Mast Light

High-mast lighting mounts multiple high-output floodlights on masts of roughly 20–50 metres to cover large areas with few structures: highway interchanges, ports and container terminals, rail yards, airport aprons, and stadium surrounds. LED conversion transformed the category — 300–600 W LED heads replacing kilowatt-class HPS with better uniformity and instant restrike — but design discipline still governs: symmetric or asymmetric distributions are selected per mast position, aiming is engineered in the photometric study, and lowering systems (winch and ring) or maintenance access are part of the specification since mast-top service is costly. Wind loading and pole foundation requirements are structural, not lighting, deliverables.
