Quick Answer: For a 500W–750W LED high mast light such as the FORTOMO 40SL, a practical installation height is typically 20–35 meters, depending on the application, lighting area, pole spacing, required lux level, and beam angle.
What Is the Best Installation Height?
There is no single height suitable for every high mast lighting project.
As a general starting point:
15–25 m: Large parking areas and smaller industrial yards
20–30 m: Logistics centers and industrial facilities
25–35 m: Ports, container yards and large outdoor areas
30–40 m+: Very large sites requiring wide-area coverage
The final height should always be confirmed through a photometric lighting simulation.
40SL 500W–750W LED High Mast Light
The FORTOMO 40SL is a high-output LED lighting solution available in 500W, 600W and 750W configurations.
Key features include:
Up to 150–170 lm/W
Multiple NEMA optical distributions
Different beam angles for flexible light distribution
IP66 protection
10kV / 20kV surge protection options
100–277VAC input
0–10V, DALI, PWM and DMX512 control options
These features make the 40SL suitable for ports, industrial yards, logistics centers, large parking areas and other large outdoor applications.

How Does Beam Angle Affect Installation Height?
Beam angle is just as important as wattage.
Narrow beams concentrate light over a longer distance and can be useful for higher mounting heights.
Wide beams provide broader coverage and can be suitable for lower poles or larger spacing.
For example:
20–25 m: 500W + medium/wide beam
25–30 m: 500–600W + medium beam
30–35 m: 600–750W + suitable medium/narrow beam
These are preliminary recommendations. The actual configuration should be selected according to the site layout and required illumination.
Key Point for High Mast Lighting Design
Do not select the pole height based on wattage alone.
A good high mast lighting design considers:
Pole height + wattage + beam angle + pole spacing + lux level + uniformity.
For the FORTOMO 40SL, 20–35 meters is a useful starting range for many large outdoor lighting projects, but the final height should be verified with IES photometric data and lighting simulation.
