5-12NM+ Solar Marine Lantern (SL-C500/SL- C600)

5-12NM+ Solar Marine Lantern
5-12NM+ Solar Marine Lantern

The SL-C500 and SL-C600 models are large solar powered marine lanterns with a visible range of 5-12NM and a service life of over 12 years.

The power supply is made from UV stabilised polyethylene and holds four (4) premium-grade solar modules and a large internal battery. The solar and battery power supply provides an increased working autonomy and is suitable for more demanding user requirements or low sunlight regions.

The solar powered lantern uses the SL-155 as a light-source, boasting a range of features including multiple lens divergences and PC programming.

The SL-C500 and SL-C600 is also available with GSM for remote monitoring and control, or integrated Type 1 and Type 3 AIS.
