Independent Underwater Review Overview
In this video, Watertrek360 conducts a complete underwater field test of three LetonPower Submariner Series budget dive lights:
-
Submariner 14s
-
Submariner 16
-
Submariner 26s
All three dive lights were purchased independently by Watertrek360 and were not provided by LetonPower.
Watertrek360 does not represent or promote any manufacturer, and all opinions are based on real-world wreck diving requirements in Northeast U.S. waters.
This review focuses on how these dive lights perform in low-visibility, cold-water, and wreck diving environments, where reliability and beam control matter more than marketing specifications.

Divers who need a focused, penetrating beam rather than wide video lighting
Control & Performance Testing (05:14 – 08:20)
Watertrek360 performs a series of practical tests across multiple environments, including:
-
Charging time
-
Runtime performance
-
Surface testing
-
Pool testing
-
Open water dives
The evaluation focuses on:
-
Light stability during continuous use
-
Beam effectiveness in murky water
-
Usability during real dive scenarios
These tests aim to determine whether the lights deliver functional performance underwater, rather than relying solely on advertised lumen numbers.
Observed Drawbacks (08:20 – 09:17)
The review also identifies limitations, including:
-
Design or usability compromises common in budget dive lights
-
Performance differences when compared to higher-end technical dive lights
These drawbacks are discussed objectively and in context of the price category.
Key Strengths (09:17 – 10:09)
Within their price range, the Submariner Series shows several notable strengths:
-
Solid construction
-
Focused beam well-suited for wreck and low-visibility diving
-
Practical performance aligned with real diving needs
-
Strong value for cost-conscious divers
The reviewer emphasizes function and reliability over marketing-driven specifications.
Overall Conclusion
The Watertrek360 review concludes that the LetonPower Submariner Series is not designed to replace high-end technical dive lights, but instead offers:
-
Dependable performance
-
Practical beam characteristics
