Marine Lantern Type 6-13NM+


The SL-155 Series are 6-13NM medium range marine lanterns, available in 2.5, 5, or 10 degree vertical distributions. A Wreck Light lantern to meet IALA recommendation 0-133 for temporary marking of danger or hazards is also available

Small Form Factor

The single tier SL-155 with multiple intensity adjustments, high levels of efficiency, and minimal wind loading, offers significant advantages over other lens stack assemblies.

Advanced PC or IR Programming

Sealite’s convenient PC Configuration Tool or IR programmer allows a host of features to be user set including ;
• Multiple intensity settings
• 310 flash settings including custom character
• Automatic effective intensity adjustment
• Adjustable on/off lux levels
• Low battery threshold
• GPS synchronisation offset
• Alarm conditions

Optional GPS Synchronisation

For flash synchronisation of lanterns a GPS module may be fitted.

When lanterns flash in synchronisation they can be clearly distinguished from other navaids and confusing background lighting – ideal for rivers and channel marking.

Optional GSM Monitoring & Control

The SL-155 lanterns may also be fitted with a GSM Cell-Phone Monitoring and Control System – enabling users to access real-time diagnostics data and change lantern settings via cell-phone. The system can also be configured to send out alarm SMS text messages to designated cellular telephone numbers.
Users can also have alarms and reports sent to designated email addresses.

Optional Type 1 or Type 3 AIS – Integrated or External

The SL-155 lanterns (5 & 10 degree models) are available with a class-leading integrated, low-powered Type 1 or Type 3 AIS.
When fitted, the AIS is encapsulated within the body of the SL-155 to maintain the weatherproof integrity and come standard with GPS.
All 3 models can also be ordered with an external Type 1 or Type 3 AIS transponder if required, along with various solar power options.
