5 Best Underwater Fishing Lights [Bright & Budget Friendly]

Night fishing is a fun experience and can be a nice change of pace from normal fishing trips. Some fish will be more active at dusk and after the sun goes down, so you may need to plan a night fishing trip to catch what you want.

The hard part of night fishing is that the lack of visibility affects both you and the fish. So you need an underwater fishing light to draw the fish towards your location. The fish gather near the light to feed, giving you clear visibility to catch. 

Based on our research, the top underwater fishing light is the Green Blob Outdoors New Underwater Fishing Light. The Green Blob won our top choice thanks to its powerful LED bulb, saltwater-resistant casings, and energy-efficient design. The Green Blob is a great general-purpose green fishing light for all kinds of fish. 

Fishing lights are an important part of any angler’s arsenal. So today we are going to talk about the top 5 underwater fishing lights. We will also talk about important features to keep in mind when shopping for underwater fishing lights.

1. Green Blob Outdoors Underwater LED Fishing Light – Best Overall

First up on our list is an industry favorite, the Green Blob Outdoors LED fishing light. True to its name, the defining characteristic of the Green Blob is its soft green light 110V light that attracts plankton and other microorganisms.

The Green Blob comes in two varieties: one with a 7,500-lumen bulb and another with a 15,000-lumen bulb. That intensity of light is strong enough for virtually any body of water at night.

The light is powered by a typical 110V plug and has 12 volts of output. The 30-foot cable gives you ample room to hang and position the light and the low-energy LED bulb can run for hours without getting hot. The bulb itself is rated for over 50,000 hours and is resistant to saltwater. There is also a version with a 50-foot cord for even more positioning flexibility. 

The green frequency of light is good for catching all kinds of fish, including catfish, crappies, snook, redfish, and more. The light is also bright enough to be used out of the water as a general-purpose bulb for your boat. The green light is pleasing to the eyes and won’t strain your vision. 

Overall, the Green Blob is the best light due to its power and sheer versatility. You can keep it on 24/7 with minimal power draw and little worry of overheating. 

2.Amarine Made 12v-24v 8W LED Submersible Light – Budget Pick

Up next on our list is the Amarine Made 12-v-24v 8W LED Submersible Light. The Amarine is an affordable and simple fishing light that has a decent lumen rating and a no-frills durable design. The fishing light itself measures about 7” long and connects to a 20’ long cord.

The light is powered by a 110-v plug and draws only generates 8W when turned on. If you do not have a plug, the Amarine comes with a clipper attachment so you can hook it to a standard DC battery 

The Amarine can put out up to 1,000 lumens and has a 360-degree design so it attracts fish from all directions.

The bulb is rated for 50,000 hours of continuous use and also has a built-in lead weight. Like most modern fishing lights, it emits a green color that attracts several types of fish. The bulb itself is fairly small but emits a significant amount of light for its size. 

The outer casing is made from a durable PVC material that provides good anti-corrosion protection. PVC is also a good thermal insulator and the hollow tube design allows effective heat dissipation. The true draw of the Amarine, however, is its simplicity.

You don’t have to worry about batteries, and the light has a waterproof design, so you can plug it in, toss it in the water, and start fishing with 0 hassle. The only downside is the relatively low lumen output. 1,000 lumens will be enough for a small pond but may have trouble in a lake or larger body of water. 

3.Bright Night Fishing 15,000 Lumen Underwater Fishing Light – Most Lumens

In third is the Bright Night Fishing 15,000 Lumen Underwater Fishing Light. The Bright Night, as the name implies, has an extremely bright LED that has a 15,000 max lumen output. The light itself consists of a series of 300 individual LEDs and can illuminate a radius of 30’. The high-quality PVC casing is resistant to saltwater and the end of the tubes are welded shut to ensure maximum protection from water. 

The Bright Night is designed to be used either as a boat light or a dock light. You can hang it off the side of your hull or you can mount it to the underside of your dock or on a support pillar. The light itself is rather large so you may have trouble placing it in a smaller vessel such as a canoe or a kayak. 

The Bright night requires a standard 110v plug and has a 30’ cord. The bulb is rated for 50,000 hours of continuous use, so you can leave it on 24/7 and use it as a general-purpose dock light. The manufacturers also offer a 4-month limited repair/replacement warranty as well as an extended 3-month warranty against factory defects. 

4.Fish Guaranteed Underwater Classic Dock Light – Best Dock Light

The fourth entry on our list is the Fish Guaranteed Underwater Classic Dock Light. This model is designed specifically for hanging off your dock but can also be used off the side of your boat. It features a 175-watt incandescent bulb, which corresponds to approximately a 3,000-lumen output.

The bulb is self-cleaning as it produces enough heat to prevent the formation of algae and other growths. That means that you never have to take it out of the water for cleaning, unlike LED lights. 

The bulb also contains a photocell that automatically turns it off during the day and on at night. The only installation requirement is a 110v power supply. Plug the control box into the outlet then lower the light into the water wherever you want. Note that the light itself is not green, but will appear green due to reflection in the water. 

This dock light features a sturdy design. The bulb is encased in a metal cage that protects the light from scratching and impacts. It also comes with a very generous 3-year warranty so you can get a full replacement if anything goes wrong. 

5.Kilofly 4-Pc Lure Bait Underwater Fishing Light – Best Battery Powered Option

Last but not least on our list is the Kilofly 4-Pc Lure Bait Underwater Fishing Light. These lights are a bit different than the others on our list because they are designed to attach to fishing lines as well as hang off your boat. The battery power and small size make them very portable.

As you would expect, the smaller size means they are not as bright as some other lights, so they are best suited for smaller bodies of water. 

Each light can last for 72 continuous hours on a single battery. The bulb component is made with 3 levels of seals, which allows the light to operate in depths up to 2,100 feet. The portability makes them extremely convenient if you are in a place that does not have an outlet or external battery to connect.

Each lure weighs only 1.5 oz., so they are light enough that they should not impact the motion of your cast very much. It is compatible with a wide range of lure attachments and you can also hang it off your dock. You have the option of traditional green LEDs, blue, white, and a multicolor pack with one of each. 

Underwater Fishing Light Buying Guide

Keep the following features in mind when looking for underwater fishing lights. 

Type

There are three major types of underwater fishing lights to choose from: Covered bulb systems, uncovered bulbs, and LEDs. Covered bulb systems are generally the most expensive and are highly durable. The main drawback of covered systems is that the cover dilutes the light and dissipates the intensity, especially for colored lights. Covered bulbs can also get covered with barnacles and algae, making them less effective. 

Uncovered bulb systems use a reactive halide gas and often use incandescent or halogen bulbs. Uncovered systems are the most commonly used because they are inexpensive and easy to maintain. Since the bulbs are uncovered, the surface gets hot enough to keep algae from forming a surface. The main downside is that uncovered bulbs are relatively fragile and can break easier. 

Lastly are LED lights. LED is the newest addition to underwater light technology and features a bright, low-energy light in varying frequencies. LED lights are also extremely portable and have long battery life. The main downside of LED lights is that they do not get hot enough to keep algae and film from forming on the casing.

Brightness

Brightness is the most important performance feature to look for. Brightness is rated in lumens. The more lumens, the brighter the light is. For most fishing situations, you want a light with a lumen rating of at least 1000 lumens or higher. Any lower and you won’t have enough light penetration to attract the fish you want. Most modern lights emit between 7,500 and 15,000 lumens. 

Colors

Color is important because the frequency of light determines what kinds of fish you will attract. So, make sure that you buy a light that is the right color to attract the fish you want. If you want a general all-purpose light, then stick with green. Green light attracts plankton and other microscopic animals and fish will follow to feed. The smaller fish are drawn to the plankton and attract larger fish. 

Aside from green, white is a good all-around underwater light color. White light absorbs quickly in the water and blue is especially useful in saltwater. White light also improves visibility more than most other light colors. UV lights are another popular option as they illuminate fluorescent fishing lines and plankton. UV lights can also work well with fluorescent lures. 

Portable or Fixed

Most fishermen will prefer to use portable fishing lights as you can remove them when you ar4e finished and they are easier to clean. However, if you need something more powerful, you may want to consider getting fixed lights on the hull of your boat or on your dock. Fixed lights are usually more powerful and bright, but you need to clean them more often because they spend the majority of their time submerged underwater. 

Durability

If you are going to be fishing in saltwater frequently, then you need to make sure it can stand the corrosive effects of saltwater. Even though fresh water is not as corrosive as salt water, it can still contain impurities and electrolytes that can cause a short in the light’s circuit.

One of the leading causes of shortened fishing lights is using mismatched metals as water can penetrate their joints easier. Additionally, a good fishing light needs to have proper heat dissipation. Lights normally have heat sinks that remove heat from the sensitive electrical components. 

Submersible vs Floating

Fishing lights can either sit on the surface of the water or sit just below the surface. Floating lights are the older of the two models and were more popular in the past. However, floating lights can attract a number of insects as well as fish. Submersible bulbs were designed to prevent insects and sit just below the surface. Submersibles have an internal weight and may have additional weight attachments so you can adjust the depth at which the light sits. 

Frequently Asked Questions

Why do I need an underwater fishing light?

Underwater fishing lights are necessary to attract fish at night. The light attracts plankton in the water and fish follow to feed. Smaller fish feeding on the plankton attracts larger fish for you to catch. 

How do I use an underwater fishing light?

If you have a portable light, you can set it directly in the water or attach it to a cable and lower it into the water. Some portable lights will sit on the surface while others will sit underwater. Fixed lights need to be mounted to the hull of your boat first before turning them on. 

What kind of batteries will I need?

Most portable underwater fishing lights use 12v batteries. New models may have rechargeable batteries and some also incorporate solar panels to charge during the day and turn on at night. 

Do I have to replace my fishing light bulbs?

Yes, some lights will need their bulbs replaced periodically. Most bulbs will have some rating indicating how long they will last. For cheaper lights, it might be more convenient to just buy a new light rather than change the bulb. 

What is the best color to use for underwater lights?

In most situations, green light is the best color to use. Green light attracts the plankton and zooplankton that other fish are attracted to. White light is another good choice that provides good visibility without penetrating the water too far. 

Are floating or sinking lights better for fishing?

It largely depends on the kind of fishing you are doing. Floating lights are good for certain types of shore casting. But generally speaking, sinking lights are better. Sinking lights penetrate deeper, do not attract bugs, and attract more fish. 

Is AC or battery power better for fishing lights?

AC power is usually a better option as it provides a more reliable source of power and does not have a time limit, unlike a battery. 

Final Words

Fishing lights are an important yet often underlooked piece of equipment. A good set of fishing lights can extend your fishing trips well into the hours of the night and improve your chances of landing larger fish.

Just remember to find a durable light with a good power rating that can handle the corrosive effects of saltwater. Most importantly, try to talk to other anglers about their lights of choice. You can often get good advice from those more experienced than you.
