The primary objective of lighting a golf course is to create an environment where golfers can safely play after sunset or on cloudy days. However, golf course lighting isn’t just about safety; it also enhances the course’s aesthetic appeal, guides players around the course, and ensures a smooth experience for both golfers and spectators during nighttime events.
Golf courses feature a mix of wide-open spaces like fairways and driving ranges, smaller areas like greens and tees, as well as pathways and water features. Each of these requires different types of lighting to achieve the desired balance between visibility, ambiance, and energy efficiency.
Different Types of Lights Used in Golf Course Lighting
Various lighting options can be used to illuminate different areas of a golf course, each type offering distinct benefits based on specific needs. These lights range from floodlights and spotlights to pathway lights and underwater lighting.
Floodlights
These lights are designed to provide a broad, intense beam of light that can cover a wide area. Due to the size of golf courses, floodlights are typically mounted on poles that range in height from 15 to 30 feet to maximize coverage. The type of floodlight used is typically an LED or a metal halide bulb, with LEDs being increasingly popular because of their energy efficiency, long lifespan, and lower maintenance costs.
LED floodlights are capable of providing high lumens output while consuming less power, making them the most economical option in the long run. Traditional floodlights, using metal halide or high-pressure sodium bulbs, provide ample brightness but tend to consume more energy and require more frequent replacement.
Floodlights are commonly placed in large areas like fairways, driving ranges, or even the rough areas to ensure complete visibility. Spacing for floodlights typically ranges from 80 to 100 feet apart, depending on the layout of the area and the required brightness.
Spotlights
Spotlights are ideal for more focused lighting applications. They create a narrow beam of light that can be directed at specific features of the golf course, such as greens, tees, water hazards, or trees. Spotlights can be used to highlight particular visual elements of the course, adding a dramatic effect while maintaining functional visibility.
Spotlights are often installed at a height of 10 to 20 feet and are positioned at key points across the course. The distance between spotlights will depend on the area being illuminated, with placements typically ranging from 30 to 50 feet apart. For example, spotlights around a green or tee box will be installed closer together to ensure complete lighting coverage of those smaller, more critical areas.
Pathway Lights
Pathway lights are low-intensity lights designed primarily for safety and guidance along walking paths or cart paths. These lights typically have a soft glow, making them ideal for ensuring golfers can move around the course safely without being distracted by overly bright illumination. They are particularly useful for marking the edges of walking or cart paths, ensuring that players can find their way back to the clubhouse, restroom facilities, or other areas at night.
Pathway lights are usually mounted on poles that stand between 2 to 4 feet tall and are placed at regular intervals, generally every 10 to 15 feet. These lights are often installed with an LED bulb for energy efficiency. While their purpose is primarily safety, pathway lights also help create a pleasant atmosphere on the course, contributing to the course’s nighttime beauty.
Underwater Lights
Golf courses that feature water elements such as ponds, lakes, or fountains benefit from the use of underwater lights. These lights are waterproof and resistant to corrosion, making them ideal for use in water features. Underwater lights serve two purposes: functional and aesthetic. On one hand, they illuminate the water features to enhance visibility, especially for water hazards like ponds, streams, and lakes. On the other hand, they contribute to the course’s visual appeal, highlighting fountains, waterfalls, or submerged rocks.
The number of underwater lights needed depends on the size of the water feature. Small ponds may only require 2 to 3 lights, while larger lakes or more intricate water features may need 10 or more lights to provide complete illumination. The placement of underwater lights is crucial for creating the right visual impact and highlighting specific features in the water.

Distance and Placement of Lights
In golf course lighting, the distance and placement of lights directly affect their effectiveness. Incorrectly placed lights can cause uneven illumination, creating dark spots or overly bright areas. The proper placement of lights ensures that every section of the course is adequately lit without wasting energy or disturbing the surrounding environment.
Floodlight Placement and Distance
Floodlights are typically mounted on tall poles, often between 15 and 30 feet high. The placement of floodlights is critical to achieving uniform coverage across large areas like fairways and driving ranges. Floodlights are usually spaced about 80 to 100 feet apart. However, the specific spacing depends on the intensity of the lights and the desired brightness levels. If more lights are used, they can be spaced closer together, resulting in more uniform coverage.
The key to proper floodlight placement is ensuring that they cover large areas while minimizing overlap between beams. Too much overlap can lead to excessive brightness, while insufficient overlap may leave areas inadequately lit. The goal is to distribute light evenly across the course, ensuring that no area is left too dark.
Spotlight Placement and Distance
Spotlights, being more focused, require precise placement to avoid wasting light or creating unwanted shadows. These lights are typically mounted on lower poles than floodlights, around 10 to 20 feet high, to allow for more control over the light’s direction. Spotlights are spaced at intervals depending on the specific feature being illuminated, such as a green, tee, or water hazard. Typically, spotlights are spaced between 30 and 50 feet apart, though the specific distance can vary based on the size of the area and the desired effect.
When positioning spotlights, consideration must be given to the type of terrain around the feature being lit. For example, lighting a bunker or sand trap requires more focused spotlights, which should be placed directly over or near the feature to avoid spilling light onto the fairway or surrounding landscape.
Pathway Light Placement
Pathway lights are installed at lower heights and spaced relatively close together to create a soft and consistent illumination along paths. Typically, pathway lights are placed every 10 to 15 feet, though this can vary depending on the width of the path and the amount of light required. On wider paths or areas with more foot traffic, the lights may need to be placed closer together to ensure uniform lighting.
Pathway lights should be placed along the edges of the walking or cart paths to prevent players from straying off the path. It is also important to ensure that pathway lights do not interfere with floodlights or spotlights, as their softer glow should not be overpowering.
Underwater Light Placement
Underwater lights are positioned at the edges of ponds, lakes, or other water features, depending on the design of the water feature. These lights are usually installed around the perimeter of the water feature or submerged at specific points to highlight particular elements like fountains or waterfalls. The number of underwater lights required depends on the size of the water feature and the visual effect desired.
For a small pond, 2 to 3 lights may be sufficient to illuminate the water’s surface. Larger lakes or intricate water features may require 5 to 10 underwater lights or more. These lights are generally placed at equal intervals around the water’s edge to ensure even coverage and to enhance the reflection effects in the water.
The Number of Lights Needed
The number of lights required for a golf course depends on several factors, including the size of the course, the areas that need to be lit, and the type of lighting system chosen. Here are some estimates for the number of lights needed for various sections of the golf course.
Fairways and Driving Ranges
Fairways and driving ranges are the largest areas of a golf course and therefore require the most floodlights. The number of floodlights needed depends on the size of the area being illuminated and the spacing between each light. Typically, floodlights are spaced about 80 to 100 feet apart, and depending on the size of the fairway or driving range, 10 to 20 floodlights may be required. For example, a large 200-yard driving range might need approximately 15 floodlights to ensure even illumination.
Greens and Tees
Greens and tees require spotlights, which provide more focused lighting. For each green, 4 to 6 spotlights may be required, depending on the size and layout of the green. For larger greens or multiple tees in close proximity, more spotlights may be needed to ensure proper lighting without creating shadows.
The total number of spotlights required for the entire golf course depends on the number of greens and tees. A standard 18-hole course may require anywhere from 72 to 108 spotlights for all the greens and tees.
Pathways
For pathways, pathway lights are generally spaced 10 to 15 feet apart, depending on the width of the path. A golf course may have several miles of walking or cart paths, and the number of pathway lights will depend on the length of these paths. For example, a 1-mile path may require 250 to 500 lights, depending on the spacing used.
Water Features
For water features such as ponds, lakes, and fountains, the number of underwater lights required depends on the size and complexity of the feature. A small pond may need 2 to 3 underwater lights, while larger lakes may require 10 or more lights. Each light should be positioned strategically around the water to ensure even illumination and to highlight specific features such as fountains or waterfalls.
The Cost of Lights for Golf Courses
The cost of lighting a golf course depends on several factors, including the type of lights used, the size of the course, the installation process, and ongoing maintenance costs. Below is an in-depth breakdown of the costs associated with lighting a golf course.

Environmental Considerations
Proper lighting systems should minimize light pollution, protect wildlife, and reduce energy consumption.
Minimizing Light Pollution
Light pollution is the excessive or misdirected artificial light that negatively affects the natural environment, disturbs wildlife, and impedes human activities like stargazing. When installing golf course lighting, special care should be taken to direct the light exactly where it is needed, preventing light from spilling into the surrounding environment.
The use of shields, baffles, and downward-facing fixtures can help to contain the light within the desired area. Additionally, using LED lights, which can be dimmed and controlled more precisely than traditional lights, helps reduce unnecessary light pollution and improves the overall quality of the golf course environment.
Wildlife Protection
Wildlife, particularly nocturnal animals, can be disrupted by artificial lighting. Bright lights can disturb their natural behavior, especially during breeding seasons. Golf courses located near wildlife habitats should prioritize low-intensity lighting and use fixtures that minimize the scattering of light.
Some golf courses have started to adopt more sustainable lighting practices, such as using solar-powered lighting in areas that don’t require strong illumination. Solar-powered lights not only reduce the strain on local electricity grids but also limit the environmental impact of lighting systems.
Energy Conservation
The environmental impact of lighting a golf course can be significantly reduced through energy-efficient choices. LED lights use less power to produce the same amount of light as traditional lighting, leading to lower carbon emissions. Many golf courses are also exploring renewable energy sources, such as solar panels, to offset the energy consumption of their lighting systems.
Smart Lighting Controls
Another way to improve energy efficiency is through the use of smart lighting controls. These systems automatically adjust the brightness of the lights based on the time of day, weather conditions, and occupancy levels. For example, lights can be dimmed or turned off during hours when no one is on the course or when there is sufficient natural light.
Smart lighting systems can help reduce energy usage and costs while maintaining the quality of illumination when it is needed. This system also allows for easier monitoring and maintenance, helping ensure the lighting remains optimal without wasting resources.
Conclusion
Lighting a golf course involves a combination of practical considerations, including safety, aesthetics, and energy efficiency.
