This article discusses the development of high mast lighting techniques and the reasons for using such techniques. One of the most important of these concerns accidents in which street lighting columns are struck. For any light distribution the relations between spacing of columns and mounting height is such, that if spacings are to be kept reasonably wide, mounting heights must increase. With greater mounting heights therefore columns can be sited farther away from carriageways, and with fewer columns or masts, collision hazards are considerably reduced. Factors influencing the design of high masts are briefly mentioned, and details of the types of foundation used are given. The various light sources used on high masts are described with examples, and the theory of light distribution from these installations is explained. Electrical requirements and maintenance operations for high mast installations are discussed and capital and maintenance costs are quoted and compared with those for conventional group A lighting columns. This comparison suggests that the higher capital costs incurred with a high mast scheme may be offset by savings in maintenance.
