1 NM Lights:

SL-15 Yellow

SL-15 The SL-15 is a 1 nautical mile range light, suitable for hazard marking, aquaculture, navigation and perimeter lighting.

2 NM Lights:

SL-60 Green

SL-60 The SL-60 is a 2-nautical-mile-range light, suitable for hazard marking, aquaculture, navigation buoys, ports and marinas, perimeter lighting, and general marine infrastructure lighting.
SL-70 The SL-70 is similar to the SL-60, but incorporates two high-performance solar modules, mounted within the lens of the unit, and angled to obtain maximum sunlight capture. This makes it a suitable choice for free-floating buoys and higher-latitude installations.

SLC-310 Lanterns

SLC-310 The SLC-310 is a state-of-the-art self-contained solar LED lantern ideal for both fixed and dynamic mounting, especially buoys.  Featuring four 2 watt solar panels and internal 12V, 7.5 Ah battery, the 20 LED light head includes 256 user programmable flash codes.

SL 20-30-50 Style Lanterns

SL-23/23.5 and SL-24 The SL-23 and SL-24 are ideal for navigation, hazard lighting, perimeter lighting and a range of other applications in low-light or high-latitude applications. The SL-23 is suitable for fixed installations, with a 7 AH sealed battery coupled with one 12 watt solar module; the SL24, equipped with dual 12 watt solar modules, is suitable for buoy installations, and will continue to capture sunlight as the buoy swings. The SL23.5 model is equipped with one large 5 watt solar module and is suitable for fixed installations.

SL-30/32 and SL-50/52 The SL 30 and SL-50 3-4 mile LED lanterns perform exceptionally well in medium-high sunlight regions, and are ideal for fixed installations including navigation, hazard lighting, perimeter lighting and a range of other applications. Both use 20 ultra-high intensity LEDs as a light source; the SL-30/32 incorporates a 1.2 AH sealed battery coupled with one 2 watt solar module, and the SL-50 a 4 AH sealed battery and one 5 watt solar module. The SL-32 and SL-52 models, specifically, are suitable for buoy or heavy-duty-cycle applications, having two solar panels each.

SL-125-C2 Complete
Lantern Assembly

SL-125, SL-125-C1 & C2 and SL-125-GPS: The SL-125 5 mile LED lantern offers a number of clear advantages, including a service life of over 7 years. The lantern uses 36 LEDs as a light source, and is completely sealed and vented to alleviate pressure buildup through air exchange, without moisture ingress. Both the lens and base are made from UV stabilized polycarbonate to provide excellent impact-resistance, and are corrosion-free. The SL-125 operates off a 12 volt battery system, and is delivered with 3 foot of standard cable for easy installation. The SL-125-C1 includes one large 16 watt solar module, adjustable to 51 degrees, and a 24 AH sealed battery, suitable for fixed installations. The SL-125-C2 includes 2 large 16 watt solar modules, adjustable to 51 degrees, and a 24 AH sealed battery. The dual module assembly allows the unit to collect solar radiation as the buoy swings. The SL125/GPS utilizes the latest advances in GPS technology to synchronize lanterns to mark a channel, port or river.  Ranges available from 5 - 7 nm and greater, please ask...

GSM Monitoring:

GSM Text Message Monitoring

GSM OPTION:  The SEALITE SL-125 light heads and certain larger self-contained lanterns are available with our new GSM monitoring system.  This allows the lantern to be monitored via cell phone SMS text messages.  The unit can be set up for daily reporting, web monitoring, and various alarm settings.  The "active current" circuit provides feedback on a daily basis about the condition of the battery and circuitry.

You provide a GSM compatible SIM card and the internal Nokia® circuit sends and receives SMS text messages.  Imagine, remote monitoring at a very reasonable cost!

This unit also offers a watch system integrating a "off station alarm" if equipped with a GPS system.  This can be programmed to monitor the location of the lantern and send an alarm if moved "off station" by 50 - 999 meters (user setting).  Great for buoys!!!
