Where Are Marine Navigation Lights Used?
Marine navigation lights ensure safety in harsh conditions, preventing collisions and guiding vessels. Our IALA-approved buoy lights offer 1-20+ nm visibility with options for BeiDou, satellite, and IoT monitoring, reducing risks and maintenance costs across industries:
Choosing the Right Visibility Range:
- 1-5 nm – Harbors, marinas, and short-range navigation.
- 6-10 nm – Coastal and medium-range applications.
- 11-15 nm – Offshore installations and deep-sea routes.
- 16-20 nm – Long-range ocean navigation for critical safety.
Extreme Conditions? No Problem.
From raging storms to freezing winters, NFS1803P is built to last.
