highmasts

Highmasts are tall, slender poles, typically made of metal, used to support lights at significant heights. They are commonly found in areas requiring extensive illumination, such as sports stadiums, airports, harbors, and large industrial sites. The primary purpose of a highmast is to provide broad and uniform light coverage over a wide area, minimizing shadows and ensuring visibility.

The design of a highmast often includes a winch system or a lowering ring to facilitate maintenance and bulb replacement of the luminaires. This mechanism allows the lighting array to be safely brought down to ground level, eliminating the need for specialized aerial access equipment in many cases. The height of a highmast can vary significantly, ranging from 20 to 70 meters or more, depending on the specific application and the desired coverage radius.

Materials used in the construction of highmasts are chosen for their strength and durability, often galvanized steel or aluminum, to withstand environmental conditions and the weight of the lighting fixtures. The foundation is also critical, requiring substantial concrete footings to provide stability against wind loads and the overall weight. The strategic placement of highmasts is crucial for optimal light distribution and to prevent light pollution in surrounding areas.
