Introduction
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
certied 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 asher 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 specications. 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 ashing
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.

SL-15 with User-Adjustable Flash Settings
1–2NM+ Solar Marine Light
Sealite marine lanterns may be set to any of IALA recommended flash settings. These can be set via
rotary switches inside the lantern or the IR remote or via the Sealite Configuration Tool.
Symbols
SEALITE® code reference is listed by number of flashes
For the latest version of this document visit www.sealite.com
or email i[email protected]
FL Flash followed by number Eg. FL 1 S, one flash every second
F Fixed
Q Quick flash
VQ Very quick flash
OC Occulting; greater period on than off
ISO Isophase; equal period on and off
LFL Long flash long
MO Morse code ( ) containsletter
For example, VQ (6) + LFL 10 S means 6 very quick flashes followed by a long flash, during a
10-second interval.
The amount of power your lantern draws through the night depends on the duty cycle, i.e. the amount of
time on as a proportion to the timing cycle. For example, 0.5 seconds on and 4.5 seconds off equals a
10% duty cycle.
It is best to operate at the lowest duty cycle appropriate to the actual needs of the application.

Conguration Settings
The intensity and ash codes can be changed using the switches on the lamp circuit board or with the
IR Remote Control. The lamp intensity and ash code settings are set to the last detected change,
carried out with the IR Remote Control or by changing the switch positions.
Example #1: If the intensity is set at 100% with the intensity switches, and is then set to 50% using
the IR Remote Control, the intensity setting will change to 50%. If the intensity is then set to 75% using
the switches, the new intensity value will be 75%.
In order to change intensity settings using the IR Remoter Control, the lamp must be powered.
The lamp can detect a change in switch settings if they are changed while the light is powered down.

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 at 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
ashing 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 tted. Always discard old batteries in a safe manner.
Long Term Storage Instructions (>4 weeks)
If light is required to be stored for longer than 4 weeks, please turn the light off using the internal
ON/OFF switch (and external ON/OFF switch where tted).
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 at 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 tted 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.

Trouble Shooting
Problem Remedy
Lantern will not activate. • Ensure internal switch (or external switch where tted) 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.
