Underwater lighting for fishing is not a new concept. Technology has been around for a few years. Anybody who goes night fishing on a regular basis understands the importance of these lights and uses them on a regular basis. Underwater fishing lights plain and simple attract bait fish, and we all know that bait fish attract game fish. Using underwater fishing lights can optimally up your chances for a successful night fishing trip.
Underwater fishing lights are not a catch-all for night fishing. You still need to do your research on being at the right place to catch your particular species, but with the addition of underwater lighting, you will increase your fish catch dramatically.
One of the main reasons underwater fishing lighting works so well to catch game fish is because most of the game fish have a distinct advantage over the "food chain" at night. The "food chain" is attracted by the underwater fishing lights but they cannot react quickly enough to escape the game fish.
The reason Game fish have an advantage, is because most of them can detect color at night. This creates a distinct advantage for the game fish over the food chain because not only can they detect changes in light intensity but also color contrast. It has been known for some time that fish, shrimp, and insects are attracted to light at night, but you probably are asking yourself what color is best at night. The answer to this question is the color blue or green because they attract both the food chain and the game fish.
There is commercial underwater lighting that gets its power source from a land-based system, but these systems are used primarily by shoreline landowners and will not be discussed here. When looking for a quality underwater fishing light look for the following properties in order,
1) high intensity
2) emit its light color similar to the fishes space (blue or green)
3) powered by a portable electrical power supply
4) be submersible. Property number 4 is recommended because land-based or boat-mounted lights lose a great deal of their light energy to the reflection off the surface of the water.
