Solar Marine Lantern type SL-75 is a next-generation solar marine lantern with up to 5NM visible range. The lantern incorporates dual high-performance solar panels for maximum sunlight capture and utilises the latest Bluetooth® technology for convenient configuration and maintenance.
This model is supported by the SealitePro® mobile application, designed to allow for complete programming (via Bluetooth®) of the SL-75 lantern. An easy to use interface and with intelligence built-in, the App enables access to read and program the lantern functions from a mobile device up to 50 metres away.

This innovation reduces maintenance times, improves productivity, and reduces safety risks by minimising the need to climb onto a buoy or structure. Optional GPS synchronisation allows two or more units set to the same flash character to flash in unison, improving visual recognition of boundaries or marine channels. Optional GSM gives users the added ability to control and monitor the asset remotely.
