Quick Answer
Glow sticks can be used underwater for night fishing, but their effectiveness is limited due to water absorption and scattering of light.
How Glow Sticks Work Underwater
Glow sticks are designed to produce light when a chemical reaction occurs between two chemicals, phenyl oxalate and hydrogen peroxide. However, when submerged underwater, this reaction is significantly slowed down due to the pressure and water absorption of light. As a result, the glow stick’s duration is reduced, typically lasting from 5 to 10 minutes, compared to 6 to 12 hours on land.
Choosing the Right Glow Stick for Underwater Use
When selecting a glow stick for night fishing, look for ones with a higher lumens-per-hour rating, such as those rated for 12+ hours on land. These sticks will provide a more intense glow that can penetrate the water at depths of up to 10 feet. It’s essential to choose sticks with a UV-resistant coating to prevent the light from being absorbed by the surrounding water.
Safety Considerations and Techniques
When using glow sticks underwater, it’s crucial to handle them carefully to avoid accidental activation or damage. To maximize the effectiveness of the glow stick, position it near the water’s surface to create a clear visual signal for other boats or fishing gear.
