The Ultimate Buying Guide for Underwater Fishing Lights
Underwater fishing lights can change how you fish. They bring fish closer to your boat or dock, especially at night. Choosing the right light needs a little know-how. This guide helps you pick the best one for your needs.
Key Features to Look For
Good lights have features that make fishing better and the light last longer. Always check these things before you buy.
Brightness (Lumens)
- Lumens Matter: This number tells you how bright the light is. More lumens usually mean more fish attraction, especially in murky water.
- Consider Water Clarity: Clear water needs less bright lights. Murky or stained water needs very bright lights to penetrate the darkness.
Color Spectrum (Light Color)
- Green Lights: Green is often the top choice. Many baitfish and game fish react strongly to green light.
- White Lights: White lights look natural but might not attract as many fish as green. They are great for seeing your immediate surroundings.
- Mixed Colors: Some lights switch between colors. This lets you test what works best on any given night.
Power Source and Battery Life
- Voltage: Most lights run on 12V DC, connecting directly to your boat battery. Check the voltage requirement carefully.
- Battery Options: Some portable units use rechargeable batteries. Look at how long the battery lasts on a single charge.
Important Materials and Durability
Since these lights live underwater, the materials they use are very important. Good materials keep water out and handle tough use.
Housing Material
- Aluminum: High-quality, anodized aluminum housings offer excellent heat dissipation and strength. They resist corrosion well.
- Plastic/Polycarbonate: Lighter and often cheaper, these materials must be UV-stabilized so sunlight doesn’t make them brittle when the light is out of the water.
Sealing and Waterproofing
- IP Rating: Look for an IP68 rating. This rating means the light is fully protected against dust and continuous immersion in water. This rating is crucial for long life.
Factors That Improve or Reduce Quality
Quality isn’t just about the brand name. Specific design choices make a light work better or fail sooner.
Heat Management (Improves Quality)
LEDs get hot. High-quality lights have built-in heat sinks, usually metal casings, to pull heat away from the LEDs. Overheating shortens the lifespan of the light dramatically.
Corrosion Resistance (Improves Quality)
Saltwater is harsh. Stainless steel components and specialized coatings prevent rust and corrosion. Cheap hardware will fail quickly near the ocean.
Beam Angle (Affects Use)
A wider beam angle spreads light over a bigger area near the boat. A narrower angle shoots light deeper. Think about whether you are fishing shallow flats or deep water.
User Experience and Use Cases
How you plan to use the light changes what you should buy.
Boat Mounting vs. Dock Mounting
- Boat Lights: These need to be rugged and often submersible (for transom mounting) or portable. They usually connect straight to the boat’s 12V system.
- Dock Lights: These often use simple AC power or solar/battery setups. They need easy installation above or just below the waterline.
Portability
If you fish from different piers or borrow boats, choose a compact, battery-powered model. These setups offer great flexibility.
10 Frequently Asked Questions (FAQ) About Underwater Fishing Lights
Q: Why do fish come to underwater lights?
A: The lights attract tiny organisms, like plankton. Small baitfish eat the plankton. Larger game fish then come to eat the baitfish. It creates a feeding frenzy.
Q: Is it legal to use underwater lights everywhere?
A: Not always. Some states or local regulations limit the color or intensity of lights you can use while fishing. Always check your local fishing rules.
Q: Do green lights attract more fish than blue lights?
A: Generally, yes. Green light travels well through water and mimics the natural light spectrum that many saltwater and freshwater species see best.
Q: Can I leave my underwater light on all night?
A: You can, provided the light is rated for continuous use and your battery can handle the drain. High-quality lights manage heat well enough for long runs.
Q: What is the difference between surface and submersible lights?
A: Surface lights sit on top of the water or just below the surface. Submersible lights are fully sealed units designed to be lowered deep into the water column.
Q: How far away from the boat should I place the light?
A: Placing the light a few feet away from the boat hull often works best. This avoids shining light directly onto your gear and keeps the concentrated light pattern where the fish gather.
Q: What voltage do most boat lights use?
A: Most permanent boat installations run on 12 Volts DC to connect easily to standard marine batteries.
Q: How long should a good LED fishing light last?
A: Quality LED assemblies are rated for 50,000 hours or more of use. If the heat management is poor, the lifespan drops sharply.
Q: Should I buy a light with a wide or narrow beam angle?
A: Buy a wide beam for shallow water or when fishing directly under the boat. Choose a narrow beam if you need to penetrate deep, clear water columns.
Q: Are cheap lights worth the risk?
A: Usually, no. Cheap lights often use poor seals, leading to water intrusion and early failure. Investing in a well-sealed, heat-managed light saves money in the long run.
