SL-70 Marine Lanterns

2-3 MN Max. Range
IP68 Sealing
2,5 W Solar Energy

The SL-70 is a high-performance solar marine lantern with a visible range of 2 to 3 nautical miles. In high-insolation regions, the SL-70 intensity can be adjusted to achieve a range exceeding 3 nautical miles (depending on color). A higher-capacity 16Ah battery pack is available for areas requiring extended autonomy. The SL-70 has a service life of up to 12 years.

Optional GPS synchronization allows two or more units to be configured with the same flash character so that they flash simultaneously. Synchronized flashing helps clearly distinguish them from other navigation aids and background lighting, making it ideal for rivers, marina entrances, channel marking, and aquaculture applications. It improves visual recognition of navigation boundaries, contributing to safer vessel passage.

The importance of maintenance in ports

Maintenance is one of the fundamental pillars to ensure the safety, durability, and operability of a marina. Beyond the initial investment in infrastructure, a proper maintenance strategy helps extend the lifespan of facilities, reduce emergency interventions—typically associated with additional costs—and ensure continuity of service for users.

The origin of today's IALA A and IALA B system

Why is port marked in red in one country and in green in another? It's not a coincidence, it's history. Until the 1970s, more than 30 different buoyage systems coexisted around the world, with no common standard between countries. This lack of standardisation led, in 1971, to a chain of fatal accidents in the Strait of Dover.
