Every light sold my Underwater Fish Light is fish guaranteed! We guarantee that you will see fish at your dock light. If you don’t see any fish, you can get a full refund. While fish lights seem to magically attract fish to your dock, it is actually a simple, scientific process. Any light under the water, no matter what the color, will attract fish. When lights are placed under the water, they reflect off particles in the water. These tiny little particles enhance a natural food source for bait fish. These bait fish are then attracted to the light. Once the bait fish are attracted, they bring in bigger game fish like snook, tarpon, and bass.

Some lights attract fish within minutes of installation, while others can take up to a few weeks. Fish attendance depends on your location. Even though you might not have fish the first night, the process is still the same. It just takes a little longer for the fish to find your light and become accustom to the feeding cycle. Once the fish find the light, they will be back every night. Therefore, it is important for the fish light to run on a photocell. The photocell will ensure the light comes on every night, and off every morning. After a few weeks, you will have built a feeding cycle with the fish in your area and will see them coming back. It is similar to that of a dog. If you feed him every day at 5:15, he will be waiting for his food at 5:10.

As time goes on, more fish will appear at the light. Most of them will be bigger than the ones that preceded them. These lights do more than just attract fish, they create a natural aquarium in your backyard! The best part about these lights is that they do not harm the fish or any other marine life. They enhance a natural food source for the animals as well as provide countless hours of entertainment for anyone that sees them.

We have thousands of customers that live up north in areas like New York, Maryland, and Canada. During the winter months, the water will obviously freeze. The bulb itself will be able to survive the cold-water temperatures, but the wire will not be able to survive the ice. All of our systems come equipped with a GFCI plug that turns the system off if there is anything wrong with it. When ice forms under the water, it tends to shift back and forth. This shifting will cut into the wires that are leading out to the bulb. Whenever there is a damage in the system. The GFCI will turn the system off, causing the light to no longer illuminate. Therefore, because of the ice formation in northern areas, customers should take their lights out of the water to protect the wire.
