15m to 18m is enough for high mast steel street light pole ?

High mast steel street light poles that range from 15 meters (m) to 18 meters in height are typically used for large-scale outdoor lighting applications such as highways, streets with wide roadways, industrial areas, sports complexes, and other public spaces that require extensive illumination. Here are some key considerations when it comes to these types of street light poles:

  1. Material: The pole is usually made of steel due to its strength, durability, and resistance to weather conditions. Steel poles can be hot-dip galvanized or coated with a protective layer to prevent corrosion.
  2. Height: The height of the pole, ranging from 15m to 18m, allows for the installation of multiple light fixtures at different levels, providing a wider coverage area and reducing shadows. The specific height chosen will depend on factors such as the width of the roadway, the desired mounting height above the ground for the luminaires, and local regulations.
  3. Light Fixtures: High mast lights often use sodium vapor lamps, metal halide lamps, or more recently, LED lamps as the light source. These fixtures can be quite powerful, with individual lamps ranging from a few hundred watts to over a thousand watts each.
  4. Pole Design: The pole may have a single vertical column or could be designed with an “A” frame or “H” frame shape for additional stability. Some poles are also equipped with guy wires or anchor bolts to provide extra support against wind and other environmental forces.
  5. Accessories: Poles may include accessories such as climbing spikes for maintenance access, electrical conduits, and protective covers for the base of the pole.
  6. Foundation: Due to the height and potential wind load on the pole, a proper foundation is critical. This could involve a concrete footing or a drilled shaft depending on the soil conditions and structural requirements.
  7. Regulations: Local building codes, safety standards, and lighting guidelines must be followed when installing high mast street light poles. This includes delineating the height, spacing, and photometric performance of the light fixtures.
  8. Maintenance: High mast lights require regular maintenance to ensure they continue to operate efficiently and safely. This can include periodic cleaning, bulb replacement, and structural inspections.

When planning the installation of a high mast steel street light pole, it is essential to work with professionals who can assess the specific needs of the location, design a system that meets those needs, and ensure compliance with all relevant regulations and standards.
