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.
