How Deep to Put Green Fishing Light?

In this article, we’ll explore How Deep to Put Green Fishing Light and discover the best practices for getting the most out of this fishing tool.Fishing enthusiasts often seek innovative techniques to improve their catch, and one such method gaining popularity is using green fishing lights.

These lights are designed to attract fish, making them easier to spot and increasing the chances of a successful catch. However, knowing how to use these lights effectively is crucial, including determining the proper depth at which to place them.

What is a Green Fishing Light?

A green fishing light is a specialized underwater light designed to illuminate the surrounding water with a green hue.

Green is chosen because it has a shorter wavelength and higher energy, making it more visible to fish in various water conditions. Depending on the fishing scenario, these lights are typically submersible and can be used from docks, piers, or boats.

Is a Green Light Good for Fish at Night?

A green light can benefit fish at night, mimicking the natural moonlight they are accustomed to. Green light doesn’t disturb or stress their circadian rhythms, allowing for a more relaxed and natural environment.

It also enhances visibility without startling the fish, making it easier for them to navigate and locate food. However, the intensity and duration of the green light should be carefully controlled to ensure it is optimal for the fish’s well-being.

How Do You Use an Underwater Fishing Light?

Using an underwater fishing light involves submerging the light source in water to attract fish. Typically, the light is attached to a weighted base or float, ensuring it stays submerged at the desired depth.

The light emits a specific wavelength, often green or white, which attracts plankton and baitfish. This, in turn, draws larger game fish to the area for feeding.

Anglers usually position the light near their fishing spot and wait for the fish to gather, making it easier to catch them during night fishing sessions.

Understanding the Importance of Light Depth

Light Penetration in Water

Before we delve into the optimal depth for green fishing lights, it’s essential to understand how light behaves in water.

Different light colors penetrate water to varying degrees, and water clarity also plays a significant role. Light can penetrate clear waters, making it more visible to fish at greater depths.

Attracting Fish with Green Lights

Research has shown that certain fish species are attracted to green light. This phenomenon is known as phototaxis, where fish are naturally drawn to light sources.

By using green fishing lights strategically, anglers can create an enticing environment that attracts various fish.

How Deep to Place a Green Fishing Light

Factors to Consider

The depth at which you should place your green fishing light depends on several factors. These include the type of fish you’re targeting, water clarity, weather conditions, and the fishing location. Generally, a good starting point is setting the light 2 to 4 feet below the water’s surface.

Different Fishing Scenarios

  • Shore Fishing: When fishing from the shore or a dock, place the green light near the edge, allowing it to illuminate the water around it.
  • Boat Fishing: If fishing from a boat, suspend the light over the side. Experiment with different depths until you observe fish gathering around the light.

Setting Up Your Green Fishing Light

Dock Fishing

To set up a green fishing light from a dock, follow these steps:

Securely attach the light to the dock’s edge or nearby structure.

Lower the light into the water, ensuring it’s fully submerged.

Please turn on the light once it’s in the desired position.

Wait a few minutes for the fish to gather around the light.

Boat Fishing

For boat fishing, the setup process is slightly different:

  1. Attach the green fishing light to a sturdy line or rope.
  2. Lower the light into the water on the side of the boat.
  3. Adjust the depth of the light based on the fishing conditions and species targeted.
  4. Please turn on the light and give it some time to attract fish.
  5. Best Practices for Using Green Fishing Lights

To maximize your success with green fishing lights, consider these best practices:

  • Use multiple lights to cover a larger area and attract more fish.
  • Avoid shining regular white lights directly into the water, which can scare fish away.
  • Experiment with different depths and positions to find the most effective setup.
  • Ensure the light is securely fastened to prevent it from drifting away.

Common Mistakes to Avoid

  • Placing the light too deep or too shallow missing out on potential fish activity.
  • Using a light that’s too bright, may deter fish instead of attracting them.
  • Neglecting to turn off the light when not needed, wasting its battery life.
  • Failing to clean the light regularly reduces its effectiveness over time.


Using green fishing lights can be a game-changer for avid anglers looking to improve their fishing success. By understanding the importance of light depth and employing the best practices for setup, anglers can create an alluring underwater environment that attracts various fish species. Remember to experiment with different depths and positions and consider the specific fishing scenario to make the most out of your green fishing light.


Does a green light attract fish?

Green Light and Fish: Fact and Fiction


  • Yes, green light can attract fish, especially under certain conditions.

Here’s why:

  • Visibility: Green light penetrates water further than red or blue light, making it more visible to fish in deeper or murkier waters.
  • Food chain: The green wavelength is associated with plankton, a food source for small fish. This can attract baitfish, which in turn draw predators.
  • Commercial use: Fishermen and dock owners often use underwater green lights to attract fish.


  • Greenlight alone is unlikely to harm healthy fish. It’s not as detrimental as UV light, which can damage their eyes and DNA.
  • However, bright light of any color can disrupt fish behavior and natural rhythms. Excessive light pollution can affect their feeding, breeding, and migration patterns.

Best Bait:

  • The best bait for green lights depends on the target fish species and their predominant food sources. In most cases, live bait like shrimps, minnows, or insects will work well.

Underwater Lights:

  • Yes, fish can be attracted to underwater lights of various colors, including green. The key factors are brightness, wavelength, and placement.
  • However, overusing lights can have negative consequences for the ecosystem. It’s important to use them responsibly and consider potential ecological impacts.

Is the green light okay for fish?

The effect of green light on fish depends on several factors:

1. Purpose of the Light:

  • Fishing: Green lights are often used in the underwater fishery because they penetrate water better than other colors, especially in murky or shallow water. This attracts plankton and smaller fish, which draw larger fish looking for food. However, using artificial lights for extended periods can disrupt fish behavior and ecosystems.
  • Aquarium: In aquariums, green light can be used for aesthetic purposes or to promote plant growth, as some plants respond well to specific wavelengths of green light. However, using only green light can stress fish and affect their sleep patterns.

2. Intensity and Duration of Light:

  • Bright lights: Any color light that is too bright or used for extended periods can stress fish and harm their vision.
  • Dim lights: Dimmer green lights may be less disruptive, but their effectiveness for attracting prey or encouraging plant growth will be lower.

3. Species of Fish:

  • Different fish species have varying visual abilities and preferences for light wavelengths. Some fish may be more sensitive to green light than others.

Therefore, there is no simple answer to whether the green light is “okay” for fish. It depends on the context, intensity, and species of fish involved.
