How to choose the height of a bollard
The height of a bollard significantly affects the light distribution and its practical applications. Here is how the height of bollards can influence various aspects of lighting:
1. Coverage Area
Low bollards (up to 50 cm) are ideal for illuminating paths and walkways, providing focused and localized light. The coverage area is limited, so low bollards are often used in series to create a continuous effect along a path.
Medium bollards (50-100 cm) offer a wider light coverage than low bollards, spreading light over a larger area. They are suitable for illuminating larger spaces like courtyards and gardens.
High bollards (over 100 cm) can illuminate much larger areas, making them suitable for parking lots, squares, and large open spaces. The elevated height allows light to spread evenly over a wide surface.
2. Light intensity and orientation
Low bollards tend to project light directly downward, creating localized illumination and reducing glare. This makes them ideal for marking paths and specific points.
Medium bollards offer a good combination of direct and diffused lighting, useful for illuminating moderately sized areas without creating sharp shadows.
High bollards provide more diffused and less intense light at ground level, which can be useful for general illumination of large areas without causing glare.
3. Safety and Visibility
Low bollards enhance path visibility without dazzling passersby. They are particularly useful for marking walkway edges and increasing pedestrian safety.
Medium bollards provide good general visibility and are tall enough to avoid being covered by low vegetation, enhancing both safety and aesthetics.
High bollards offer wide and diffused lighting that increases the overall visibility of the area, contributing to a safe environment without creating overly intense light points.
4. Aesthetics and landscape design
Low bollards, discreet and minimal, integrate easily into the landscape without dominating the scene. Ideal for gardens or spaces with low vegetation.
Medium bollards provide a visual balance between height and lighting, helping to define spaces without being too invasive.
High bollards can serve as design elements, becoming focal points in the landscape. Strategically used, they can define garden architecture and guide visual flow.
