Here at Underwater Fish Light, we can guarantee that you will see fish, but being able to catch them is up to you! With just a few simple techniques, you can become a night fishing pro and reel them in all year long! All you need is a good lure or bait, proper casting technique, and some patience.

The main reason these lights work so well is the feeding cycle they produce. The fish come back night after night, because they know they are able to find food at your dock. When you first put in your fish light, you might immediately see fish. At this point, you need to use all the patience you have! Don’t start casting into the light as soon as it has been installed. Let the fish build a relationship with the light so they can become comfortable. For the first few days, you can even through out some shrimp, or any other type of food the fish might light to eat.

The last thing to do before you start casting is to get the right type of lure for your hook. The ideal lure to use in the fish light would be any kind of lure that looks like a small minnow with a moving tail. This will imitate the bait fish that normally circle the light and attract the predator fish.

Once you have everything ready, you are ready to cast! The most important thing to remember when fishing at a fish light is to NOT cast directly into the light. The best way to catch fish is to cast past the light and slowly reel the lure through the light. This will imitate the activity of the baitfish swimming in the light. Usually, you will be able to catch a fish within the first five casts, so use these tools to your advantage and get out there! Remember, we love to see any photos you have of the great fish you have seen or caught at your lights, so feel free to send them into us! Good luck fishing!

This question actually has multiple answers. To answer this question, you must first decide what light series you interested in, and the amount of light you want to see by your dock. Here at Underwater Fish Light, we have three different series; Natural Green, Vibrant Green, and Caribbean Blue. Each series of light is ideal for different types of water clarity and will emit a different amount of light.

For customers interested in purchasing our Natural Green lights, the ideal water clarity is in between crystal clear and mid-clarity water. The bulbs on these systems are 175-watt bulbs that illuminate a clear/white color. This white color then reflects off the particles in the water, showing a green color on the surface. These small particles attract the bait fish in the area, which in turn attract the predator fish (snook, tarpon northern pike, etc.). Because these lights illuminate white, they do not cut through murky water very well. That is why they are ideal for up to mid-clarity water. In ideal water, the Natural Green series will shine a 10-foot circle on the surface of the water.

Vibrant Green light systems are designed to cut through murky water. The Vibrant Green light systems have 250-watt bulbs which illuminate green, allowing it to cut through murky water and be more successful for customers in rivers, lakes, bayous, and any other location that has dark water. Even though the lights illuminate green, they still reflect off small particles in the water to attract the baitfish and predator fish. This light system will give a 15-foot diameter circle on average in waterways.

The biggest thing to consider before purchasing the Caribbean Blue lights is the water clarity at your dock. For these lights to show the ideal color, the water needs to be crystal clear. If the Caribbean Blue bulb is placed in murky water, it will actually illuminate an amber/yellow color. If your water is murky, there is obviously more dirt and sediment that is in the water. These actually change the color of the light, because the blue light reflects off these particles, creating more of an amber glow rather than the blue most people are expecting. That is why any possible customers must have clear water in order to enjoy the color as intended.

For this question, there is no single answer. It all depends on the light you are interested in. After weighing your options, it all comes down to your personal preference. If you purchase a light that does not meet your expectations, you have 60-days to return the light and upgrade it to one you think will work better. Just give us a call at 855-FISH-LIGHT and we can answer any other questions you might have!



Fish lights look dim in some waterways due to a combination of factors. The clarity of the water coupled with the power of the light bulb will determine how effective the light will be. If a weaker bulb is placed into murky water, the light will definitely be dim. If a stronger bulb is put into murky water, the light will work much better. For this reason, we carry two levels of lights. We have a 175-watt system and a 250-watt system. Our 175-watt Natural Green system is ideal for customers that have clear to moderately murky water at their dock. Our 250-watt Vibrant Green systems are for customers that have murky water. The Vibrant Green is a larger bulb that is designed to cut through murkier water and give those customers a satisfying color in their waterway.

Some customers notice that their bulbs get dim at certain times of the year. Our customers on the west coast of Florida experience this every summer. During the summer in Florida, it not only rains every day, but the Okeechobee river is also released and drains out through the rivers and canals that lead to the Gulf of Mexico. During this time, the water in the canals all around southwest Florida gets extremely dirty. In some areas, the water will go from rather clear, to almost coffee-colored. Because of this, customers will notice their lights becoming very dim. Once seeing this, some will think their bulbs are going bad or the system is malfunctioning. Fortunately, that is not the case, but sadly, there is no way to fix this issue with the water. Customers that purchased the Vibrant Green Series will most likely only notice a small difference, while those with the Natural Green Series will see a drastic change in their light. While this is quite inconvenient, there is no way to avoid the drainage that comes from the Okeechobee or the rain Florida experiences every summer. Most customers simply wait it out, and their light goes back to normal within a few weeks as the dark water drains out.

The important thing to remember is that whenever your light goes dim, it is not a fault within the bulb. If a bulb were to go bad or “burn out”, it will simply never turn back on. If you ever notice that your light has become dim, you have two options; wait for the water to clear back up, if you know it is due to weather, or upgrade your bulb by purchasing a larger, more powerful system.

Installing your Underwater Fish Light is much easier than many people think. We design our lights for easy installation, so you can see fish as soon as possible! We want you to spend most of your time enjoying the fish, not trying to puzzle out how to put it together. Below is a step-by-step installation guide for your dock light system.

  1. Mount the Control box on post/pillar at least 4 to 6 feet above the water­line and within 10 feet from an APPROVED GFI OUTLET
    1. (Do Not over tighten the screws used to mount the control box to the pillar/post).
    2. Note: Mount control box in well-ventilated area.
  2. Once you determine where you would like to place the light, attach the weight with the zip ties, to the light cord a min­imum of 3 inches from the base of the housing/bulb, and lower the weight into the water. The bulb unit will follow.
    1. BE SURE TO HANDLE WITH CARE!!!! DO NOT BANG/BUMP BULB!! Keep in mind, the bulb must always be sub­merged under water, and may never be lit out of the water.
  3. Attach the photocell to the top of the box, taking care to align the prongs
    1. The photocell attaches with a “twist-lock.” Simply align the prongs and twist the photocell on
  4. Plug the 10-foot power cord with the inline GFCI
    1. Once again, be sure your outlet is a GFCI approved outlet
  5. Wait for dark, and enjoy!
