Tendelux Underwater Fishing Light, 110V & 12V Super Bright Green LED Submersible Light Attractants for Docks, Boats or Kayaks, IP68 Rated for Fresh & Salt Water (30ft Cable)
- Class-leading Performance - Designed by balancing the brightness and consumption, the FG20H green fishing light provides 2300 lumens of illumination by consuming only 23 watts. Unlike many fishing lamps that are integrated with resistors (which will dramatically bring down the power efficiency), we used a 95% efficiency rating power transformer and massively improved the output.
- Fishing with Efficiency - Simply drop the light into your fishing spots and wait for a great outcome. The lights will create a food chain of small phytoplankton, baitfish and predatory fish which will make it a lot easier to catch your favorite fish.
- Improved in Every Aspect - Comes with all-around better materials and premium quality accessories. We also made a big upgrade on heat transferring, the lamp contains 6 separated light bars to make sure it doesn't get over-heated and so massively ensures durability and performance.
- Versatile Applications - Comes with 110 Volt AC power supply, 12V DC battery clamps and cigarette lighter adapter, you may power the lamp with common 12V batteries, portable power stations as well as boat and home outlets, perfect for dock lighting as well as boat fishing.
- Keep Away from Marine Fouling Organisms - If you need to use the fishing light under the sea on a long-term basis, we would suggest taking it out every 15 days to clean the surface and wait for it to dry out before placing it underwater again - this can effectively prevent unwanted biofouling, especially the barnacles which are hard to clean and will strongly affect the light performance.

The Ultimate Buying Guide for Underwater Fishing Lights
Underwater fishing lights can change how you fish. They draw baitfish closer. Then, bigger fish follow the bait. This guide helps you pick the best light for your needs.
Key Features to Look For
Good lights have several important features. These features make your fishing trips better and last longer.
Brightness and Color Spectrum
- Lumen Output: This measures how bright the light is. More lumens usually mean a bigger attraction radius. For murky water, you need higher lumens. Clear water needs less.
- Color Type: Green and blue lights work best underwater. Green light travels well in most water. Blue light works great in very clear, deep water. Some lights offer multiple colors.
Power Source and Battery Life
- Voltage: Most lights run on 12V DC power. This connects easily to your boat battery.
- Runtime: Check how long the battery lasts on a full charge. Longer runtime means you can fish late into the night without worry.
Durability and Waterproofing
- IP Rating: Look for an IP68 rating or higher. This rating confirms the light is fully protected against water immersion.
- Design: The housing must handle bumps and constant vibration from the boat.
Important Materials
The material used in the light housing affects its life and performance.
Housing Material
- Stainless Steel: This is the best choice for saltwater use. It resists corrosion very well. It is strong and durable.
- High-Grade Plastic (Polycarbonate): This works well for freshwater or temporary use. It is lighter and often cheaper. Ensure the plastic is UV-resistant.
Lens Material
The lens protects the LEDs. Tempered glass lenses offer the best scratch resistance. Polycarbonate lenses are more impact-resistant but can scratch over time.
Factors That Improve or Reduce Quality
Not all lights perform the same. A few details separate the good from the great.
Quality Boosters
- Quality LEDs: High-quality LED chips last longer and produce a more consistent light output. Cheaper LEDs often flicker or fail early.
- Heat Dissipation: Good lights spread out the heat they produce. Effective heat sinks (often part of the metal housing) keep the LEDs cool. Cooler LEDs last much longer.
Quality Reducers
- Poor Seals: If the waterproof seals fail, water enters the unit. This quickly destroys the electronics.
- Cheap Wiring: Thin, low-quality wires can break easily or corrode where they connect to the power source.
User Experience and Use Cases
Think about where and how you will use the light.
Mounting Options
- Surface Mount: These lights attach directly to the hull bottom. Installation is generally easier.
- Through-Hull Mount: These lights are installed through a hole in the hull. They offer a cleaner look and often better performance because the light sits completely outside the hull. This is more common on larger boats.
Fishing Scenarios
- Night Fishing from a Pier: A simple, portable light powered by a small battery pack works well here.
- Deep Sea Trolling: You need powerful, durable lights that can handle deep water pressure and constant movement. Stainless steel housing is a must.
- Bait Containment: Some anglers use lights inside live wells to keep bait calmer and easier to see before a cast.
10 Frequently Asked Questions (FAQ) About Underwater Fishing Lights
Q: Do underwater fishing lights actually attract fish?
A: Yes, they work. The light attracts small organisms and baitfish. Bigger fish come to eat the smaller ones. This creates a feeding hotspot around your boat.
Q: Which color light is best for freshwater fishing?
A: Green light is generally the top choice for freshwater. It cuts through the common tannins and sediment found in lakes and rivers.
Q: Can I leave the lights on all night?
A: You can, but check your battery capacity first. Leaving them on too long will drain your boat battery. Use a timer if you want them on for specific hours.
Q: How far below the water surface should the light be mounted?
A: Mounting the light near the bottom of the hull is standard. The goal is to aim the light downward and slightly outward to maximize the illuminated area.
Q: Will saltwater damage the light housing?
A: Saltwater is highly corrosive. Only use lights specifically rated for saltwater, usually those made of 316-grade stainless steel.
Q: What is the difference between LED and Halogen underwater lights?
A: LEDs are much more energy-efficient and last longer than old halogen bulbs. LEDs also produce less heat, which is better for the surrounding water.
Q: Is it legal to use these lights everywhere?
A: Regulations change by location. Some areas restrict light use during certain seasons or near specific spawning grounds. Always check local fishing rules.
Q: How do I wire a 12V light to my boat?
A: Connect the positive wire from the light to a positive terminal on your battery or fuse block. Connect the negative wire to a negative terminal. Use marine-grade connectors for safety.
Q: Can I use a light that is not fully submerged?
A: Some lights are designed for surface use, but dedicated underwater lights must be fully submerged to work correctly and avoid overheating the internal components.
Q: How much should I expect to pay for a good quality light?
A: Entry-level lights might start around $50 to $100. High-end, powerful, and durable stainless steel units often cost $200 or more.
