Apollo-155
Long Range Lantern Adjustable from 4-12nm+
Apollo-155 Model
The Apollo-155 is the next generation in marine aids to navigation.
To utilise the latest technology, Sealite has designed a lantern using the world’s most
advanced LEDs. These highly efcient LEDs can be congured individually to create not just a
ashing lantern, but also a sectored lantern, rotating lantern, and even more complex sectors
with multiple ash codes in the same lantern.
The Apollo-155 incorporates a sophisticated thermal management system. Sealite’s in-house
engineers custom designed this complex aluminium extrusion which is used as a heat sink for
the LEDs and LED driver board.
The distinct lens of the Apollo-155 has 16 optical elements controlling the light emissions for
the LED in a two-dimensional manner; completely unique to the industry. The 16x LEDs in each
lens individually cover 45° horizontally and 5° vertically.
The optic also facilitates internal sectoring across broad range of output requirements.
Like all Sealite marine lanterns the Apollo-155 has a specically designed circuit board that
controls automatic dusk to dawn operation, LED operation and many functions that can be
specically requested, such as current monitoring, GSM, GPS or radio-control.
The lantern can be congured using a simple, user-friendly computer program.
Sealite Apollo-NPS
Sealite’s APOLLO SL-155-NPS non-precision sector lantern is adjustable from 4–9M+ and has
been designed to suit a range of applications.
The distinctive lens of the SL-155-NPS has 16 optical elements controlling the light emissions
for the LED in a two-dimensional manner; completely unique to the industry.
The optic facilitates internal sectoring across a broad range of output requirements.
Sealite can produce almost any combination of colours and angles and meet the requirements
of our customers.
Customers need to identify each colour and angle, Flash codes, range and any other specic
requirements.
The Apollo-NPS is hand built to each set of unique customer requirements. Due to the unique
build of each light, the Apollo-NPS cannot be recongured as much as a standard Apollo.

Long Range Lantern Adjustable from 4-12nm+
4.6 Intensity Selection
Using the Sealite Lantern Programmer, Sealite lanterns may be set to a standard light intensity to
meet installation requirements. The desired intensity range may be set in nautical miles (nm - with
dependence on listings of atmospheric transmissivity and background lighting conditions), candela
(cd) or direct pulse width modulation (PWM) (see image 5).
Atmospheric Transmissivity (AT) – when a light beam passes through the atmosphere the atmospheric
transmissivity factor indicates how much light is absorbed by the atmosphere. For example, when AT =
0.85 this means that 85% of the original light intensity is visible after 1nm. Consequently 15% of light is
lost to atmospheric absorption.

• Click the “Intensity” tab at the top of the Sealite Lantern Programmer
• From the “Intensity Selection” box, type in the desired lantern range (nautical miles)
• Next select the “Atmospheric Transmissivity” level from the drop down eld
• Next select the “Background Lighting Conditions” level from the drop down eld (for standard
marine applications select “Night, No Background Lighting”)
• Once selections entered/made, the lantern will automatically send the setup instruction to the
lantern (eg. lantern will automatically change setup)
Option 2: Desired Lantern Intensity (Candela)
• Click the “Intensity” tab at the top of the Sealite Lantern Programmer
• From the “Intensity Selection” box, type in the desired lantern intensity (candela)
• Once selections entered, the lantern will automatically send the setup instruction to the lantern
(eg. lantern will automatically change setup)
Option 3: Direct Pulse Width Modulation (PWM) Value
• Click the “Intensity” tab at the top of the Sealite Lantern Programmer
• From the “Intensity Selection” box, either type in the desired pulse width modulation value (%) into
the eld OR/ move the horizontal scroll bar to the desired PWM

4.7 Effective Intensity Correction
Depending on the ash code selected, the effective intensity may be adjusted.
As per IALA Recommendation E-200 Part 4, effective intensity is dened as: “The luminous intensity
of a xed (continuous) light, of the same relative spectral distribution as a ashing light, which would
have the same luminous range as a ashing light under identical conditions of observation”.
Sealite has provided you with the most common methods for effective intensity adjustment as follows:
• Schmidt-Clausen
• Allard
• Blondel-Rey-Douglas
• Allard-Ohno-Couzin
PLEASE NOTE: the lantern Effective Intensity Correction is set to “None” as default. No effective
intensity correction will therefore be applied to the lantern setting.
To program the lantern Effective Intensity Correction (see Image 5):
• Click the “Intensity” tab at the top of the Sealite Lantern Programmer
• From the “Effective Intensity Correction” box, select the desired lantern effective intensity
correction mode from the list available
• Click the “Set Intensity” button to send the new setup instruction to the lantern
