Introduction
Congratulations! By choosing to purchase a Sealite lantern you 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.
As a commitment to producing the highest quality products for our customers, Sealite has been independently
certified as complying with the requirements of ISO9001:2008 quality management system.
Sealite lanterns comply with requirements of the US Coast Guard in 33 CFR part 66 for Private Aids To
Navigation.
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 ultra bright LED 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

Technology
Sealite is the world’s fastest growing manufacturer of marine aids to navigation. We
employ leading mechanical, optical, hardware & software engineers to create innovative
products to service the needs of our customers worldwide, and offer the widest range of
solar-powered LED lanterns in the marketplace.
Electronics

Sealite employs leading in-house electronic engineers in the design and development of software and related
circuitry. All individual electronic components are sourced directly by Sealite procurement staff ensuring that
only the highest quality components are used in our products.

LED Technology

All marine lanterns use the latest advancements in LED (Light Emitting Diode) technology as a light source.
The major advantage of LED’s over traditional light sources is well established in that they typically have an
operational life in excess of 100,000 hours, resulting in substantial savings to maintenance and servicing
costs.

Precision Construction

Commitment to investing in the design and construction of injection-moulded parts including optic lenses, light
bases and a range of other components ensures that all Sealite products are of a consistent & superior quality.

Optical Performance

Sealite manufactures a range of marine LED lenses moulded from multi-cavity dies. Complex shapes such as
the SL70, BargeSafe™ and 16-segment multi-focus lenses are a testament to the company’s superior
in-house lens manufacturing capabilities and outstanding optical performance.

Award-winning, Patented Technology

Several United States and Australian patent registrations are held on Sealite’s range of innovative designs,
with other regional patents pending in Canada, United Kingdom and Europe.

Installation
Charging the Battery

New lanterns should be left in the sun for 1-2 days to ensure battery is charged before placing
in service. Please note, lantern will re-charge even when switch is turned to ‘OFF’ position.

Preferred Installation Location
For best lantern performance, ensure solar modules are not covered and are in clear view
of the sky with no shadows.
1. The SL-15 will be supplied preset to the requested flash code.
2. The light can be directly positioned in your desired location. Secure it, utilising the 4 x holes in the
flange. Ensure the light is bolted to an even, flat surface.

Flash Codes
Adjusting the Flash Code

1. Remove the 4 x battery cover screws and lift the cover and battery out of the compartment to
expose the adjustment plug.
2. Unscrew the adjustment plug.
3. Using a small flat bladed screwdriver adjust the Flash Code to the desired setting.
4. Cover the light, in darkness, for at least 30 seconds to activate the light sensor. Make sure the
light is flashing correctly.
5. Uncover the light and wait at least 30 seconds to make sure the light turns off in daylight.
6. Insert the adjustment plug and replace the battery.
7. Replace the cover and secure using the 4 x screws. Do Not over tighten screws.
8. Position the light in your desired location and secure, utilising the 4 x holes in the flange. Ensure
the light is bolted to an even, flat surface.

Maintenance and Servicing
Designed to be maintenance free, the SL-15 requires minimal attention, though the following
maintenance and servicing information is provided to help ensure the life of your Sealite product.
1. Cleaning Solar Panels - occasional cleaning of the solar panels may be required. Using a cloth and
warm soapy water, wipe off any foreign matter before rinsing the panels with fresh water.
2. Battery Check - inspection of batteries should be performed every two years (minimum) to ensure
that the charger, battery and ancillary electronics are functioning correctly. Using a voltage meter,
check that the battery voltage is at least 3.6 volts under 50mA load, and ensure all terminals are
clear of foreign matter.

Replacing the battery
The SL-15 lantern is the only compact marine lantern with a double sealed battery compartment. This
provides the user with the ability to change the battery after years of operation.
1. Remove the 4 x battery cover screws and lift the cover and battery out of the compartment to expose
the adjustment plug.
2. Unscrew the adjustment plug.
3. Use a small flat bladed screwdriver to turn unit OFF.
4. Unscrew positive and negative battery leads.
5. Discard old battery in a safe manner. Please remember to recycle where possible.
6. Reattach positive and negative leads to new battery and then place back into case.
7. Switch lantern ‘ON’ via internal switch.
8. Cover the light, in darkness, for at least 30 seconds to activate the light sensor. Make sure the light is
flashing correctly.
9. Uncover the light and wait at least 30 seconds to make sure the light turns off in daylight.
10. Insert the adjustment plug and replace the battery.
11. Replace the cover and secure using the 4 x screws.
Care must be taken to observe the polarity of the battery before the leads are re-connected, and
ensure the replacement battery is correctly fitted. Always discard old batteries in a safe manner.

Long Term Storage Instructions (>4 weeks)
Storage temperature, the length of time in storage and the initial charge level of the battery pack all
effect the amount of charge retained by the battery pack during storage.
We recommend:
•

Turn the lantern off at the ON/OFF switch (pg6),

•

Store the lantern in a cool dry place

Importantly, the higher the storage temperature the greater the loss in battery pack charge over time.
Note: When the internal ON/OFF switch in the OFF position the solar panel will still recharge the battery
in direct sunlight.

Trouble Shooting
Procedure
1. Remove the 4 x battery cover screws and lift the cover and battery out of the compartment to expose
the adjustment plug.
2. Unscrew the adjustment plug.
3. Using a small flat bladed screwdriver switch the ON/OFF switch to the OFF position.
4. Insert the adjustment plug and replace the battery.
5. Replace the cover and secure using the 4 x screws. Do Not over tighten screws.
6. Repeat these steps to re-activate your light when it is removed from storage.
Note: when fitted with the optional EXTERNAL ON/OFF switch, for correct operation of the EXTERNAL
switch, the INTERNAL switch must be set in the OFF position.
If the INTERNAL switch is set to the ON position, the operation of the EXTERNAL switch is
bypassed and the lantern is ON.

Problem

Remedy

Lantern will not activate.

• Ensure internal switch (or external switch where fitted) is set to the ‘ON
position.
• Ensure lantern is in darkness.
• Wait at least 45 seconds for the program to initialise in darkness.
• Ensure switch setting is on a valid code (See Flash Codes section of this
manual).
• Ensure battery terminals are properly connected.
• Ensure battery voltage is above 3.6 volts.

Timing codes will not change.

• Turn rotary switch several times to ensure contacts are clear.

Lantern will not operate for the
entire night.

• Expose lantern to direct sunlight and monitor operation for several days.
Sealite products typically require 1.5 hours of direct sunlight per day to
retain full autonomy. From a discharged state, the lantern may require
several days of operational conditions to ‘cycle’ up to full autonomy.
• Ensure solar module is clean and not covered by shading during the day.

ON/OFF Switch (SL-15-SW)

An optional external ON/OFF switch can be installed on request (additional charges will apply).
For correct operation of the EXTERNAL switch, the INTERNAL switch must be set in the OFF position.
