The Angler’s Secret Weapon: Your Guide to Buying a Fishing Black Light
A fishing black light, also known as a UV flashlight, might seem like a strange tool for fishing. However, these lights unlock a hidden world of fish attraction and tracking. They make certain materials glow brightly, helping you find the best lures and even spot fish activity in low light. Ready to upgrade your night fishing game? Here is what you need to know before you buy.
Key Features to Look For
When shopping for the best fishing black light, focus on these important traits:
1. UV Wavelength (The Power of the Light)
- What to look for: Most effective fishing black lights operate between 365nm and 395nm (nanometers).
- Why it matters: Shorter wavelengths (like 365nm) are purer UV light and cause a stronger glow. Longer wavelengths (closer to 395nm) mix more visible purple light with the UV. For maximum glow on lures, aim for 365nm if possible.
2. Brightness and Output
- What to look for: Check the light output, often measured in milliwatts (mW) or just the number of LEDs.
- Why it matters: A brighter light penetrates water better and makes your fluorescent lures pop from farther away. Don’t settle for a weak keychain light.
3. Durability and Waterproof Rating
- What to look for: Look for an IP rating, such as IPX7 or IPX8.
- Why it matters: You will be around water! A good rating means the light resists splashes or even brief submersion. Rugged aluminum casings are also great for resisting bumps.
4. Battery Life and Type
- What to look for: Consider rechargeable batteries (like 18650) or easily available standard batteries (AA or AAA).
- Why it matters: You do not want your light dying halfway through a night trip. Long battery life ensures reliability when you need it most.
Important Materials and Construction
The materials used determine how long your black light lasts. High-quality construction keeps water out and light focused.
- Casing Material: Aircraft-grade aluminum is the best choice. It resists rust and handles drops well. Plastic casings are cheaper but break easier.
- Lens Quality: A clear, high-quality glass lens transmits the UV light efficiently. Poor plastic lenses can distort the beam or yellow over time.
- LED Emitters: Look for reputable LED brands. Cheap emitters burn out faster or produce less intense UV light.
Factors That Improve or Reduce Quality
Quality isn’t just about the price tag. These factors truly separate a great light from a mediocre one.
Quality Enhancers:
- True UV Filters: The best lights have filters that block almost all visible purple light, showing you only the intense UV glow. This makes fluorescent colors stand out sharply.
- Heat Dissipation: Powerful UV LEDs get hot. A good metal body acts as a heatsink, keeping the light running strongly for longer periods.
Quality Reducers:
- “Fake” Black Lights: Many cheap flashlights labeled “UV” just produce a dim, purplish light. They do not emit enough true UV radiation to make lures glow properly.
- Poor Seals: If the battery cap or lens housing lacks good rubber O-rings, water will get inside and ruin the electronics quickly.
User Experience and Use Cases
How will you actually use this light on the water?
Checking Lures:
This is the most common use. Many modern fishing lures have UV-reactive paints. Before dark, shine the black light on your jigs, crankbaits, and soft plastics. If they glow bright blue, green, or pink, they will attract fish in deep or dark water. If they do not glow, they are less effective at night.
Tracking Fish Activity:
Some fish species excrete substances that reflect UV light. Experienced anglers use black lights to scan the water surface for subtle glowing patches, which can indicate where fish are feeding or moving. This technique helps you target the right spot.
General Utility:
A black light is also useful for spotting subtle stains or leaks on your boat or gear in the dark. It acts as a powerful, focused flashlight when needed.
10 Frequently Asked Questions (FAQ) About Fishing Black Lights
Q: What is the main purpose of using a black light for fishing?
A: The main purpose is to check if your fishing lures have UV-reactive paint. These glowing lures attract fish better in low-light or deep water conditions.
Q: Does a black light actually attract fish directly?
A: Not usually directly. The light helps you see what the fish see. Fish are attracted to the bright, glowing pattern of the lure you present to them.
Q: Which wavelength is best for checking lures?
A: Wavelengths around 365nm are generally considered the best because they produce very little visible light, making the fluorescent lure colors pop the brightest.
Q: Can I use my regular purple flashlight as a black light?
A: Maybe, but probably not well. Regular purple lights often have too much visible light mixed in. A true UV light focuses on the invisible spectrum that makes the lure materials shine.
Q: Do I need a super expensive black light?
A: You need a quality one, but not necessarily the most expensive. Focus on getting that 365nm wavelength and good waterproofing over brand names.
Q: How waterproof should my fishing black light be?
A: Look for at least an IPX7 rating. This means it can survive being dropped into the water for a short time without breaking.
Q: How do I test if my lure is UV reactive?
A: Turn off all other lights. Shine the black light directly onto the lure. If the lure glows brightly in a color other than white, it is UV reactive.
Q: Are black lights safe for my eyes?
A: While generally safe when used briefly, you should never stare directly into a powerful UV beam. Always use protective eyewear if you plan on using the light for many hours.
Q: Does this work for all types of fishing?
A: It works best for night fishing, deep water fishing, or fishing in murky water where visibility is low. It is less necessary for bright daytime fishing.
Q: Can I use this light to find baitfish?
A: Yes. Some microscopic organisms and plankton react to UV light. Shining the light over the water can sometimes reveal areas where baitfish are concentrated, as they disturb these glowing particles.
