have become the owner of one of the most advanced LED marine lanterns in the
world.
Sealite Pty Ltd has been manufacturing lanterns for over 25 years, and particular care has been taken
to ensure your lantern gives years of service.

By taking a few moments to browse through this booklet, you will become familiar with the versatility of
your lantern, and be able to maximise its operating function.
Operating Principle
The solar module of the lantern converts sunlight to an electrical current that is used to charge the
battery. The battery provides power to operate the lantern at night.
The flasher unit has very low current requirements. A microprocessor drives an array of ultra bright
LED’s through a DC/DC converter, which enables the LED’s to operate within the manufacturer’s
specifications. The battery is protected from over-charging within the circuit to ensure maximum
battery life.
On darkness, the microprocessor will initiate a program check and after approximately 1 minute begin
flashing to the set code.
The Sealite Radio Controlled Lighting System works by using a hand held radio controller to activate
and setup an entire port, harbour or channel. The system utilises an embedded RF module operating
in the 2.4Ghz ISM Band.
The lights can be configured for up to 15 different light groups. This allows the Harbour Master to
independently control different areas, such as multiple channels.
Due to the handheld nature of the Radio Controller, it can be used from any position in the port or
harbour. This can allow for easy and efficient inspection or activation of different light groups without
affecting other lights.
The standard radio controller broadcasts a command message to all lights within range. This range is
approximately 1.4km (0.7 nautical miles). If a higher gain antenna is used the range can be extended.
Each light within range will receive, decode and re-send the message to all surrounding lights. Each
light also has an operational range of 1.4km.
For distances, greater than 1.4km there may be a delay in those lights receiving the command. The
further away the lights are from the controller the longer it will take the command to propagate to all
lights.
