SL-75 Marine Lanterns

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

The SL-75 is a self-contained solar lantern with a visible range of up to 5 NM. The beacon incorporates high-performance dual solar panels to maximize solar energy capture and uses the latest Bluetooth® technology for convenient setup and maintenance. This model is compatible with the SealitePro® mobile app, designed to enable full programming (via Bluetooth®) of the SL-75 beacon. With a user-friendly interface and built-in intelligence, the app allows access, reading, and programming of beacon functions from a mobile device up to 50 meters away. This innovation reduces maintenance time, improves productivity, and lowers safety risks by minimizing the need to climb onto buoys or structures.

Satellite connectivity is now available as an option

The SL-75 is compatible with Satcom. An optional integrated Iridium® satellite module enables two-way monitoring and control via the Iridium low-earth-orbit satellite network. This provides full visibility, control, and reporting of assets via the Star2M portal. Optional GPS synchronization allows two or more units to be configured with the same flash character so they flash simultaneously, improving visual recognition of navigation boundaries.
