13-19NM Long Range Marine Lantern (SL-300-2D5)
The SL-300-2D5 Series are 13 to 19NM long range marine lanterns with 2.5 degree vertical distribution, suitable for a range of applications.
High Intensity, Small Form Factor
The SL-300-2D5 series offers multiple intensity adjustments to over 46,000cd luminous intensity in a single tier (over 93,000cd 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.
Advanced Thermal Management
The SL-300-2D5 Series features precision lower, mid and upper heat sinking. The custom designed heat sinks are interconnected, and designed to maintain an appropriate LED temperature across a wide range of duty cycles, enabling the lanterns to run efficiently whilst maintaining a compact size.
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-300-2D5 Series may also 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.
