How Much Light Source Is Needed For A High Rise Pole Light?

The light source power of a high mast lighting pole must meet the lighting needs of a large area while ensuring uniform illumination and energy efficiency. This requires scientific calculation based on the illumination range and target illumination. To match the illumination area with the power, for example, an area with a diameter of 30 meters (such as a small square) with an average illumination of 10-20 lux requires a total power of 200-400W. This can be achieved with 4-6 50W LED light sources evenly distributed across the light panel. For a large square or stadium with a diameter of 50 meters, with an illumination of 20-50 lux, a total power of 600-1000W is required. This can be achieved with 8-12 100W light sources, arranged at different beam angles (30° in the center, 60° at the edges) to ensure uniform illumination across the entire area (deviation ≤15%). Installation height affects power consumption. For 15-20 meter high pole lights, the power consumption is 10-15W per meter of height (e.g., 15 meters x 15W = 225W); for 20-30 meter high pole lights, the power consumption is 15-20W per meter (25 meters x 20W = 500W). Increased height requires increased power to compensate for light transmission loss (as the distance doubles, the illumination drops to 1/4). For example, a 25-meter high pole light requires approximately 30% more power than a 20-meter high pole light to maintain the same ground illumination.

High-efficiency LED light sources (above 130 lm/W) are favored when it comes to light source type and efficiency. Compared to conventional metal halide lamps, they provide 50% more brightness at the same power. For instance, a 400W LED lamp uses less power and energy than a 600W metal halide lamp. One light source is not as good as a combination of several light sources. It makes it simple to change the brightness in various places. Low maintenance costs result from the fact that only one light source needs to be replaced in the event of damage. Additionally, it improves heat dissipation, which prolongs the light source's life.

How to Choose How Many Light Sources to Use for a 20-meter High Mast Light

Depending on the application scenario and design specifications, a 20-meter high mast light usually needs four to twelve light sources.

1. Use 4-6 150–200W LED light sources, each covering 50–80 square meters, for parking lots and roads.

2. Use 8–10 100–150W LED light sources, each covering 30–50 square meters, for parks and squares.

3. Use 6-8 200–300W LED light sources, each covering 80–120 square meters, for industrial areas and warehouses.

Traditional high mast light maintenance requires aerial work platforms, which is costly and poses safety risks. The Phoebus high mast lighting pole features an innovative electric lift system. Using a built-in winch and steel cable, the light panel can be easily lowered to the ground for inspection or light source replacement. The lift is smooth and reliable, and equipped with a fall protection device to ensure safe operation. Furthermore, a built-in ladder structure allows technicians to easily access the pole for inspection, doubly ensuring maintenance efficiency.

Phoebus high mast lighting pole is made of premium Q235B steel that has been hot-dip galvanized to achieve an anti-corrosion rating that satisfies GB/T13912 standards and wind resistance that surpasses level 12, making it appropriate for salt spray and humid environments like industrial and coastal areas. Long-term stable operation is ensured by the IP65 protection rating of the electrical box and light panel, which are both waterproof and dustproof. Transportation and on-site installation are made easier by the modular design's speedy assembly and disassembly.
