Dock Light Systems

We have many customers that have purchased our Natural Green light many years ago and now wish to upgrade to the Vibrant Green bulb. Unfortunately, we cannot simple attached the new bulb to their system. The Natural Green lights are 175-watt bulbs. These bulbs are powered by 175-watt ballasts, or transformers, inside the control box. The Vibrant Green lights are 250-watt bulbs and are powered by 250-watt ballasts inside the control box. Unfortunately, the 175-watt Natural Green ballasts are not powerful enough to light the 250-watt bulbs.

For those customers that wish to upgrade, they would have to purchase an all new Vibrant Green system to reap the benefits of the brighter light. Underwater Fish Light does give customers a sixty-night money-back guarantee. So, any customer that is within the sixty-night period is welcome to return their Natural Green system and exchange it for the brighter Vibrant Green system.

Many people want more lights after they purchase their first. Whether it is to create a better ambiance, or to just bring in more fish, everyone seems to want more! Unfortunately, getting more lights is not as simple as just connecting a new bulb and cord to your current control box, but fret not! It is still easy to get more lights at your dock!

Each bulb on an Underwater Fish Light is connected to its own portion of underwater rated wire. It also must be powered by its own ballast, or transformer, in the control box that is mounted on the dock. If you have a single light dock system, you cannot add another light bulb to your wire. One ballast is not powerful enough to power two bulbs at full capacity.

If you do have dock system that you would like to add more lights to, you have a couple options. Underwater Fish Light gives every customer a sixty-night money-back guarantee for all systems. If you are within that sixty-day period, you are more than welcome to bring the light back to us, and we will exchange it for a larger system. If you are out of the sixty-day period, you are still able to get more lights on your dock! All you would need to do is purchase another fish light system, just make sure you have another outlet available at your dock!

Our Caribbean Blue Lights are very unique and eye-catching. They create a different ambiance than the usual green Underwater Fish Lights, and definitely stand out of the crowd. Many people are interested in these lights over the green lights, but they have several questions. They want to know if the blue will attract the same amount of fish, how the blue will work in their waterway, and if the blue is as bright as the green lights.

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.

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!

The single most frequent customer tech issue stems from nicks in the wire that leads out to the bulb. These nicks can be caused my multiple things; fish hooks, boat propellers, or marine life. Every high-end fish light comes equipped with a GFCI plug. This gives the light, and your dock, an extra layer of protection in case anything was to happen (nicks in the wire, broken bulb, power surge, etc.). If the wire leading to your bulb is nicked or cut in any way, the GFCI plug will turn the system off. This is to ensure that no electricity is leaking into the water, which obviously, can have terrible results. The GFCI also shuts off to prevent the ballast (or transformer) inside the box from overheating. If the system did not have a GFCI plug to shut it off, it would continue to run with nicks in the wire causing electricity to leak into the water and the ballast to overheat, which in turn will ruin and melt your entire system. By using Wire Shield to protect the wire, the fish hooks or marine life will scrape the Wire Shield and not injure the wire. Wire Shield is a simple product that is easily installed. Essentially, it is a heavy-duty rubber hose that has been sliced down the middle and comes equipped with zip-ties to attach it to your wire. All you need to do is wrap the shield around your wire and zip-tie it closed. This simple step will ensure your wire is protected for years to come!

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 Classic 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 Classic Natural Green series will shine a 10-foot circle on the surface of the water.

The Vibrant Green and Natural Green Extra Bright Series of 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!

While a bulb can break in a matter of seconds, sadly the replacement is not as fast. All bulbs from Underwater Fish Light are sealed to the wire they are connected to. Because of this, they cannot be simply screwed in and out. In order to replace your bulb, you will need to ship your wire and broken bulb to the Underwater Fish Light manufacturing facility for repair and replacement.

Replacing the bulb is a multi-step process. First, the old housing for the bulb is cut off from the wire and thrown away. Every housing is permanently sealed to the bulb. Once the glass bulb breaks, the housing is no longer usable, so it must be thrown away. Once the old housing is removed from the wire, the wire must be inspected to ensure it is reusable. If the wire has nick, cuts, or has deteriorated, it will not be reusable. Technicians test the wire by pumping air through it while it is submerged underwater. If there are any nicks or cuts in the wire, air bubbles will rise, which will indicate an unusable portion of wire. Once the wire has been deemed reusable by the technicians, it is ready to get a new bulb!

Before a new bulb is ready to be sealed to the wire, it must first get a new housing. All housings are made by hand. They are also painted by hand with antifouling paint to repel barnacles. Once he housing are built, painted, and ready, they are put together with the bulb and connected to the wire. Now, simply because the bulb is connected to the wire, does not mean that it is sealed. The technicians then take each bulb and seal it by hand. The sealant is a “secret recipe” only Underwater Fish Light uses. This ensures that the bulbs will not leak, no matter how long the sealants are exposed to the elements. After the sealant is applied, the bulb must seal overnight. After it has been tested, it is ready to ship back to you so it can light up your waterway every night!

The HID bulbs on our dock lights are self-cleaning. They generate enough heat to clean themselves off every night. Thanks to that photocell, you don’t have to worry about turning the system on, because it will come on automatically! As long as the system is on and runs every night, the bulbs will remain clean and maintenance free!
