Directional Marine Sector Lantern
The SL-ODSL is a high intensity, two-tier Omni-directional Marine Sector Lantern with a range of 7-11NM. It is designed and manufactured to withstand the tough marine environment, providing years of reliable, low-maintenance service.

Intensity Range
High intensity capabilities of up to 2600 candela in white utilising leading technology LEDs for a visible range of 7-11NM.
Enhanced Optics
The refractive optics and lens design ensures light is only projected where it is needed, allowing for greater optical range as well as power efficiency.
Bluetooth® Connectivity
Integrated Bluetooth® technology using the exclusive SealitePro® app. This allows for convenient in-field setup, configuration and maintenance from a location up to 50 metres away, using your phone or tablet.
Satellite Communications (Pending)
The SL-ODSL is available with an optional Iridium® Satellite module enabling two-way monitoring and control using the Iridium® Low Earth Orbit satellite network. Accessible via the Star2M® portal, the global Iridium® network offers genuine, pole-to-pole coverage and is the perfect communication partner for Sealite and our aids to navigation solutions.
AIS Compatible
Available as type 1 or type 3 and operating on the international VHF Marine. Mobile Band for AtoN operational status and positioning information.

Form Factor
Smallest form factor on the market to allow for easy installation and maintenance.
