Fishing lights play a crucial role in night fishing, helping anglers attract fish and improve visibility. The right number and placement of fishing lights are key to optimizing your catch.
Fish are naturally drawn to light, and the correct lighting setup can significantly increase your success. Green lights, in particular, are highly effective as they penetrate deeper into the water and are visible to fish at night. However, it’s essential to find a balance—too many lights can cause light pollution, while too few may limit your catch.
The number of lights you need depends on your boat size and fishing requirements. In this guide, we’ll show you how to calculate the number of lights based on your boat size, as well as the best light color and installation strategies to maximize your fishing experience.

Selecting the Right Number of Lights Based on Boat Size
The number of fishing lights you need depends on your boat size. Here’s a quick guide to determine how many lights are ideal for different boat sizes.
Small Boats (Under 20 feet)
For smaller boats, 1-2 lights are typically sufficient. These boats have limited surface area, so LED lights with a wide beam angle (120°) work best. Green lights are a great choice for attracting fish without overpowering the area with too much light.
- Coverage Area: Up to 10 feet on each side.
- Recommended Lights: 1-2 lights.
- Best Light Type: Green or white LED lights.
Medium Boats (20–40 feet)
For medium boats, 2-4 lights are needed to cover the larger area. Green or blue LED lights are ideal, as they attract a variety of fish species. Place the lights at key points around the boat, such as the stern, sides, and bow.
- Coverage Area: Up to 20 feet or more.
- Recommended Lights: 2-4 lights.
- Best Light Type Green or blue LED lights.
Large Boats (40 feet and above)
Larger boats require 4-6+ lights to cover the entire area. These boats often operate in deeper waters, so a combination of green and white lights is ideal for attracting fish at various depths.
- Coverage Area Over 30 feet, including both sides and around the stern.
- Recommended Lights: 4-6+ lights.
- Best Light Type: Green LED lights, white lights for deeper waters.
| Boat Size | Recommended Number of Lights | Coverage Area | Best Light Type |
| Small Boats (Under 20 feet) | 1-2 lights | Up to 10 feet on each side | Green or White LED |
| Medium Boats (20-40 feet) | 2-4 lights | Up to 20 feet or more | Green or Blue LED |
| Large Boats (40 feet and above) | 4-6+ lights | Over 30 feet | Green LED, White LED for deeper waters |
Coverage vs Beam Angle vs Installation Height
When installing fishing lights, it’s crucial to understand how the beam angle and installation height impact the light’s coverage area. The right combination ensures that your lights are effective in attracting fish while providing optimal illumination without unnecessary wastage of energy. Below, we’ll discuss how these factors affect the overall lighting setup.

1. ビーム角
The beam angle is one of the most important factors in determining how much area your fishing lights will cover. The beam angle refers to the spread of light, with narrower angles concentrating light in a smaller area and wider angles distributing light over a larger area. The choice of beam angle depends on the size of your boat and the type of fishing you’re doing.
- Narrow Beam Angle: A narrow beam angle (e.g., 30°) concentrates the light in a focused spot, ideal for attracting fish in specific fishing areas or small boats. These lights work best in shallow water or when targeting a small, concentrated fishing spot.
- Wide Beam Angle A wider beam angle (e.g., 120°) disperses the light across a larger area, making it perfect for larger boats or when fishing in deeper waters. This type of light is more effective for attracting fish over a wide radius.

- Narrow Beam: Ideal for small boats, shallow waters, and specific fishing spots.
- Wide Beam: Best for large boats, deeper waters, and attracting a broader range of fish species.
2. Installation Height
The height at which you install your fishing lights significantly affects their coverage. Lights installed higher above the water provide a broader distribution of light, which can cover a larger area. However, lights that are positioned too high may not provide enough illumination directly below the boat, which is often where fish gather. On the other hand, installing lights closer to the water surface focuses the light more precisely, increasing its intensity directly below the boat but reducing its spread.
- High Installation: Provides broader coverage but may have less intensity at the water surface. Suitable for larger boats or when targeting a wide fishing area.
- Low Installation: Increases intensity and concentration of light directly below the boat. Best for attracting fish close to the boat or when fishing in shallow areas.
キーの持ち帰り
- High Installation: Provides wider coverage, but light intensity may decrease at the water surface.
- Low Installation Increases intensity directly below the boat, but coverage may be limited.
3. Coverage vs Boat Size
The combination of beam angle and installation height directly influences the coverage area of your fishing lights, but it must be balanced with the size of your boat. Smaller boats often require fewer lights, which can be focused in specific areas, while larger boats need multiple lights placed at strategic locations to ensure full coverage.
For small boats, narrow beam angles with low installation height are sufficient to attract fish within a small area. For larger boats, wider beam angles with higher installation height work better to cover a larger area and attract fish from different directions.
Lighting Strategies for Different Fishing Environments
Fishing conditions vary depending on the environment, and each situation requires a tailored lighting strategy. Whether you are fishing in shallow or deep waters, targeting specific species, or fishing at night, it’s essential to optimize your lighting setup for the best results.
Shallow Water Fishing
In shallow waters, fishing lights should be placed close to the surface to attract fish near the top layer. Narrow beam angles (30°) work best for creating concentrated light zones.
- Recommended Lighting Setup:
- Beam Angle: 30°
- Light Placement: Close to the water surface, ideally at the boat’s stern or sides.
- Color: Green or blue lights are ideal for shallow waters as they attract various fish species.
- Lighting Tip: Position lights at an angle to maximize light spread without causing glare.
For more examples of how LED fish attracting lights are used in different aquatic environments, including docks, ponds, and offshore projects, see our application guide.
Deep Water Fishing
Deep water fishing requires lights with wider beam angles (120°) and higher placements to cover a larger area and reach deeper waters.
- Recommended Lighting Setup:
- ビーム角:120
- Light Placement: Position lights higher on the boat to spread light over a broader area.
- Color: White or blue lights are effective for deep waters, attracting fish from a greater distance.
- Lighting Tip: Use multiple lights around the boat to create a larger illuminated area.
Night Fishing
Night fishing requires strong lighting to attract fish naturally drawn to light. Green and white lights are highly effective, as they attract a broad range of fish species in low-visibility conditions.
- Recommended Lighting Setup:
- Beam Angle: 120° for wide coverage, 90° if focusing on specific spots.
- Light Placement: Place lights at both the bow and stern for 360° coverage.
- Color: Green or white lights attract a wide variety of fish species.
- Lighting Tip: Combine green and white lights for maximum effect, as green attracts baitfish, which in turn attracts predator fish.
