Which Fish Light Color Works Best?

What’s the Difference?
Here at Underwater Fish Light, we have four fish light colors to choose from! We have our Classic Series, which is a 175-watt bulb. We also have the Extra Bright Series that is equipped with a 250-watt bulb. Our Extra Bright Series sports three different colors; Vibrant Green, Natural Green, and Caribbean Blue! It doesn’t matter which color you choose. Fish will be attracted to the lights no matter what!
Both Series works great, but choosing the color all depends on your water clarity. If you have murky water, your best choice would be to go with the Extra Bright Series. If your water is more clear, the Classic Series will work great!
Our Caribbean Blue fish light systems will only work in crystal clear water. If you are unsure if the Caribbean Blue is right for you, just give us a call at 855-347-4544 and we will be happy to help you!

Finally, our Caribbean Blue Systems illuminate a beautiful ice blue that works great in crystal clear water.
How Many Fish Lights Do I Need For My Dock?

The amount of fish lights at your dock is totally personal preference. Some people like to light up all the water and seawall around their dock. This would require more dock lights. Each dock light, depending on the wattage of the bulb you chose, and the clarity of your water, will cover anywhere from a 10-15ft diameter circle. So, you will just need to measure the area you want to cover and do some math to find out how many lights you will need. Our fish light systems are available with up to 4 lights integrated into one system. This makes things easier in terms of installation and wiring. You will only need to install your multi-light fish light system once, and it will plug into one power outlet.
How Do Fish Lights Work?
While these 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. These baitfish are then attracted to the light. Once the baitfish are attracted, they bring in bigger game fish like snook, tarpon, and bass.
Some lights attract marine life within minutes of installation, while others can take up to a few weeks. Activity and attendance depend 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 little guys to find your light and become accustomed 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, you’ll start seeing much more activity at the light. Most of them will be bigger than the ones that preceded them. These lights do more than just attracting 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.
