13-21NM Long Range Marine Lantern (SL-300-1D5)

The SL-300-1D5 series are 13 to 21NM long range marine lanterns with 1.5 degree vertical distribution, suitable for a range of day and night applications.

High Intensity, Small Form Factor

The SL-300-1D5 series offers multiple intensity adjustments to over 90,000cd luminous intensity in a single tier (over 180,000cd in a 2-tier configuration). The small form factor provides minimal wind loading and convenient handling – delivering significant advantages over traditional larger lens stack assemblies.

High Efficiency

The long range lanterns produce a class-leading intensity to power ratio, making them highly efficient and suitable for solar power solutions.

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.

Optional GSM Monitoring & Control

The SL-300-1D5 series may be fitted with a GSM module for monitoring and control – enabling users to access real-time diagnostic data and change lantern settings via cell-phone.
