Introduction
Congratulations on your purchase of Red Sea’s ReefLED™.
Years of development are behind Red Sea’s ReefLED Wi-Fi lights which
have been are designed to ensure optimal coral growth and maximum
rendition of their vibrant colors.
At the heart of the unit is a compact LED array that provides a reef-safe
range of REEF-SPEC®light through a single REEF-SPEC®Blue (23,000
Kelvin) channel and an 8,000 Kelvin white channel. In addition, it has a
separate dedicated moonlight channel to provide low levels of light for
reef-safe nighttime viewing. The compact LED array is under an optical
glass, hollow lens that creates homogeneous light, giving dramatic coral
coloration and a gentle shimmer throughout the aquarium.
ReefLED can only be operated by Red Sea’s ReefBeat®app which
must be installed on a smart mobile device with internet connectivity.
ReefBeat provides a wide range of easy-to-use functions including
notifications if there is a loss of communication with your ReefLED- such
as in the case of power failure.
ReefBeat®is under constant development and over time will include
additional connected devices as well as additional aquarium management
tools.
Welcome to Red Sea’s smart reef-keeping.
Sincerely,
The Red Sea Team

Safety
PLEASE READ AND FOLLOW ALL SAFETY INSTRUCTIONS
DO NOT LOOK DIRECTLY AT LEDS REGARDLESS OF INTENSITY.
THIS DEVICE IS INTENDED FOR INDOOR USE ONLY.
CAUTION: When switched on, contact with the LED lens may cause
burns. Allow to cool before touching, adjusting or servicing.
DANGER: To avoid possible electric shock, special care should be taken
when handling a wet aquarium. For each of the following
situations, do not attempt repairs yourself; return the appliance
to an authorized service facility for service or discard the
appliance.
WARNING: To guard against injury, basic safety precautions should be
observed, including the following:
Do not operate any appliance if it has a damaged cord or plug, if it is
malfunctioning, or if it is dropped or damaged in any manner.
To avoid the possibility of the appliance, plug or receptacle getting wet,
position the aquarium stand and tank to one side of a wall-mounted
receptacle to prevent water from
dripping onto the receptacle or
plug. You should create a "drip
loop" (see Figure 1) for each cord
connecting an aquarium appliance
to a receptacle. The "drip loop"
is that part of the cord below
the level of the receptacle, or
the connector. Use an extension cord, if necessary, to prevent water
traveling along the cord and coming into contact with the receptacle. If
the plug or receptacle does get wet, DO NOT unplug the cord. Disconnect
the fuse or circuit breaker that supplies power to the appliance. Then
unplug the device and examine for presence of water in the receptacle.
Close supervision is necessary when any appliance is used by or near
children.
To avoid injury, do not contact moving parts.
Always unplug an appliance from an outlet when not in use, before
putting on or taking off parts, and before cleaning. Never pull the cord
itself to remove the plug from the outlet. Grasp the plug and pull to
disconnect.
Do not use an appliance for anything other than its intended use.
The use of attachments not recommended or sold by the appliance
manufacturer may cause unsafe conditions.
Do not install or store the appliance where it will be exposed to the
weather or to temperatures below freezing point.
Make sure an appliance mounted on a tank is securely installed before
operating it.
Read and observe all the important notices on the appliance.
Note: A cord rated for less amperes or watts than the appliance rating
may overheat. Care should be taken to arrange the cord so that
it cannot be tripped over or pulled accidentally.

Introduction to the ReefBeat app
All of Red Sea’s connected devices must be operated via the ReefBeat
app installed on an Android or iOS smart mobile device (SMD) with an
internet connection. See the full list of supported mobile phones/tablets
on our website.
Through your personal user account on the cloud, ReefBeat enables
you to set up and manage any number of aquariums and add multiple
devices to each of them. By default, all devices of the same type (such
as ReefLED) will be grouped together and, where appropriate, identical
settings will be applied to all devices in the group. Any device can be
ungrouped at any time and have full functionality as an independent
unit.
For full functionality, each ReefLED must have a permanent connection
to the internet through your home Wi-Fi network. In this mode of
operation, you will be able to see the current status of your ReefLEDs,
change the settings or receive notications on your SMD whenever you
have access to the internet.
The ReefBeat homepage will show you the current status of all of your
connected devices, and links you directly to the Settings Dashboard for
each group or for individual units.
You can install the ReefBeat on multiple SMDs by entering the same user
account details. All SMDs will have the same rights for operating and
changing all of the settings. You should keep this in mind before giving
your user details to any 3rd party.
In the event that you do not have a home network or your home network
does not have an active internet connection, you can connect and control
your ReefLEDs in Ofine or Direct Mode. However, certain functionality such
as remote access, multiple SMDs or status notications will not be available.
ReefBeat is constantly under development. For the most up to date
operation instructions, view or download the latest user guide from the
Red Sea website at www.redseash.com
If this is your rst Red Sea connected device, it is recommended that you
complete the physical installation of your ReefLED units before installing
the ReefBeat app.

Connection and initial setup
Installing ReefBeat
Download ReefBeat from the app Store or Google Play as appropriate for
your SMD. (In countries without access to Google Play an APK file and
installation instructions can be downloaded from Red Sea’s website.)
After installing ReefBeat, you will be guided through the set-up of your
ReefBeat user account and aquariums, and then you can start adding
your Red Sea connected devices. All of your user account details can be
edited only when your SMD is connected to the internet.
For full functionality Red Sea’s connected devices should be connected to
the internet and your aquariums should be set to “Online”. In the event
that you do not have an available Wi-Fi network at your Aquarium, set
it as “Offline”. You can change this setting later when WI-Fi becomes
available.
Make sure that you select the correct world time zone for where your
aquarium is located. The default is the same time zone as your SMD
which might be set for a different location.
If you’ve set up more than one aquarium, select the aquarium from the
dropdown menu at the top of the screen before proceeding.
Adding your first ReefLED to ReefBeat
Set your ReefLED to AP mode by pressing the settings button for 5
seconds (until double blink). The indicator LED should be blinking.
Tap the Add Device button ( ) from the Device Manager page, select
the ReefLED icon and follow the instructions on the app. If you are asked
to enter the device serial number, it can be found on the back of the
ReefLED unit. If not, the unique serial number of the ReefLED should

Note: If you are planning on using multiple ReefLEDs or other Red Sea
connected devices, it is recommended to connect them all to a Wi-Fi
network even if the network is not connected to the Internet and will
be operated in “Offline Mode”. (See Connectivity Modes)
Initial settings
The unique serial number of each ReefLED is the default name for the
device in the app. However, you can set a new name that you prefer such
as “Left LED”, “Right LED” etc. These names can be changed at any time
using the “Rename” function from the Device Manager.
For the first ReefLED you connect to your aquarium, you are asked to
choose between 3 REEF-SPEC®Blue / White settings that are equivalent
to various color temperatures. You must then set the Sunrise time for
Red Sea’s default preset Day program (D-Program) which is 11-hours of
daylight, 3 hours of moonlight and 10 hours of complete darkness. The
preset includes 1-hour of gradual sunrise/sunset and moonrise/moonset.
The default programs are set with the sunrise at 8:00am. Selecting a
different sunrise during the initial setup will create a new D-Program
which will be saved in your personal Program Library.
ReefBeat will now display the ReefLED Dashboard and your ReefLED will
implement the intensity for each channel according to the current time of
day. If you are installing the ReefLED outside of the day/moon light period
(i.e., during the complete darkness period), the light will not switch on and
the settings screen will show zero for all 3 channels. All of the settings on
the Dashboard are now editable. To go to the ReefBeat homepage without
editing, press the back arrow twice.
Adding additional ReefLED units
To connect an additional unit, open the Device Manager page from the
Dashboard 3-dot menu and repeat the process as above. Make sure that
you connect all the units for one aquarium to the same home network.
If you have connected the ReefLED to your home network, all additional
units connected to this aquarium will automatically be “Grouped” together
and will operate as a single luminaire. Individual units can be “Ungrouped”
(see Device Manager) if you wish to operate them as independent units.
Note: ReefLED 50 and ReefLED 90 units cannot be in the same group.
If you are connected in Direct Mode, all additional units will be
“Ungrouped” by default and must be set up individually.
ReefBeat Homepage
The ReefBeat homepage will show you the current status of all of your
connected devices, and links you directly to the settings Dashboard for
each group, or for individual units.

D-Programs
The details of a D-Program are presented as a graph that shows the
intensity of each channel for a 24-hour period starting at Sunrise. Tapping
on the points for each channel opens up a settings flag that shows the time
and intensity of the point. Channels are selected from the channel menu
on the right side of the page. The page can zoom and pan as required for
greater detail.
The currently active D-Program is shown on the ReefLED Dashboard. Tapping
on it will open the graph in view/edit mode. All other D-Programs are
accessed through the Program Library which is available from the 3-dot
menu or the Schedule page.
ReefLED Dashboard - Settings
ReefLED is designed to operate automatically according to a 24-hour
D-Program that defines the intensity of the REEF-SPEC Blue and White
channels during the day, and the moon channel at night. In addition, the
D-Program can include random cloud activity (periodic reduction in light
intensity) for a specified period of the day.
All of the settings for the ReefLED are viewed/edited from the Dashboard
which shows the current settings for the group or for an individual ungrouped
unit. Tapping on any of the sections on the dashboard opens the settings
page for that feature. Remember to press Apply or Save to implement any
changes you make to the settings.
Tapping on the Page menu provides quick access to additional functions such
as Manual Control of the unit, Program Library and the Device Manager.
Program library
Any number of D-Programs can be created in the Program Library
for each aquarium and copied for use on other aquariums. From the
Program library, D-Programs can be created, edited, deleted (except
for the Red Sea defaults), previewed or selected to be applied directly
as the current D-Program.
Schedule
The Schedule enables you to implement the same D-Program
for every day of the week or to select a different D-Program for
each day of the week. The default setting is “Daily.” Opening the
drop-down menu enables you to select any of the D-Programs
that are already saved in your Program Library. If you wish to have
a different program for different days of the week, choose the
“Weekly” option and select a D-Program for each day of the week.
The Schedule page includes a direct link to the Program Library so
that you can easily view, edit or create new D-Programs.

Editing
Each channel has start and finish points on the Zero intensity line
(which cannot be deleted) and can have a maximum of 10 points
in between.
The Sunrise point is shared by both the REEF-SPEC Blue and White
channels. Changing the time of the Sunrise shifts the entire
D-Program (daylight and moonlight) as a block along the time line.
Moving the Moonrise point shifts the moon channel settings as-is
along the time line.
Move
To move a point, select the channel, tap the point, tap the settings
flag and edit the intensity/time settings as required. NOTE: The
Sunrise and Moonrise points can be moved by pressing and sliding
the point on the graph.
Add
To add a point to a channel, select the channel, press the “+” (add
point) button and edit the details in the settings flag.
Delete
To delete a point, select the channel, tap the point, tap the settings
flag and press delete. Points without a delete icon in the settings
flag cannot be deleted.
Clouds
To set/edit the clouds, select “clouds” from the channel menu. Choose the
desired intensity of random clouds:
No clouds
low intensity (dims the light randomly by up to 15% of the set
value every 10 minutes for a period of 3 minutes)
medium intensity (dims the light randomly by up to 30% of the
set value every 10 minutes for a period of 4 minutes)
high intensity (dims the light randomly by up to 45% of the set
value every 10 minutes for a period of 6 minutes)
Drag the start and end times for the cloud activity as desired between the
sunrise and sunset of the daylight period.
Preview
At any time during editing, pressing the Preview button will send a
preview of the D-Program to the ReefLEDs. The preview will show the effect
of the 24-hour program in about 1 minute starting at sunrise and includes
the period of darkness. After the preview, the ReefLEDs will return to their
scheduled D-Program.
Create
New D-Programs are created by editing an existing one from your Program
Library and saving it with a new name. The default Red Sea D-programs can
only be saved with a new name. Custom D-Programs can either be saved
with new settings after editing, or with a new name while preserving its
original settings. Remember to save or save-as when you have finished
editing as unsaved changes will be lost.

Red Sea ReefLED™

Staggered Sunrise
The staggered sunrise feature allows you to create an enhanced
sunrise/sunset effect along the length of an aquarium for ReefLEDs
that are grouped together. Set a “delay time” of a few minutes and
the current D-Program will be implemented on each ReefLED in turn,
after the delay time you specify.
The delay will be implemented according to the order that the
ReefLEDs appear in the Device Manager.
By default, the ReefLEDs are ordered according to the order in which
they were added to the aquarium.
• A new ReefLED will always be added at the bottom of the list.
However, the order of ReefLEDs can be changed at any time using the
“Move” function: Device Manager > Device Line menu > Move.
Using the Move function, you can easily change the staggered sunrise
from starting on the right side of the aquarium to starting on the left.
The “Identify” function will make the individual ReefLED blink a few
times so that you can easily identify each ReefLED when setting their
order for the staggered sunrise effect:
• Device Manager > Device Line menu > Identify.
ReefLED - Additional Effects
Acclimation
Acclimation allows corals to get used to the ReefLED lights by starting
at a lower intensity and gradually increasing the intensity every day
over the acclimation period.
For systems that have not had LED lighting in the past, we recommend
starting at 50% of the intensity set in the D-Program and allowing 50
days to reach the full program intensity. When replacing other LED
lights, a shorter period may be possible. However, in such cases we
recommend you check your corals daily for signs of stress as there are
differences between LED lighting systems.
When setting the acclimation period, the reduced intensity settings will
be represented on the D-program graph by a dashed line for the REEF-
SPEC Blue and White channels. This will also be shown in the same
format on the Dashboard.
The acclimation period will be implemented automatically on all
D-Programs that are part of your schedule.
Lunar Cycle
Activating the Lunar Cycle implements a 28-day moon phase cycle
based on the settings for the moon channel in the D-Program. This is
instead of having the same moon-light effect every day. Editing the
Lunar Cycle setting enables you to make the full moon on a particular
day of the week, when you know you will be home to enjoy it.
When setting the Lunar Cycle, the reduced intensity settings will be
represented on the D-program graph by a dashed line for the Moon
channel. This will also be shown in the same format on the Dashboard.
The Lunar Cycle will be implemented automatically on all D-Programs
that are part of your schedule.

for Notifications and Firmware updates, which cannot be done offline.
When your SMD is not connected to the same network, no current data
about the device will be shown in the ReefBeat homepage. You can
change the settings from Offline to Online from “My Aquariums” in the
homepage main menu.
Offline Direct mode – Limited functionality
If your ReefLED is not connected to a network, you will need to
connect to its access point directly from your SMD every time you
wish to access it. When connected to the ReefLED in Direct mode, you
will not have any functionality that relates to groups of devices such
as Staggered Sunrise. Copies of the same D-Program can be used for
multiple ungrouped units. However, this and all other settings will
have to be implemented one unit at a time.
When your SMD is not connected to the ReefLED, no current
data about the device will be shown in the ReefBeat homepage.
Notifications and firmware updates are not available for offline units.
When operating in direct mode, you can decide if you want to leave
the ReefLED AP active all the time or turn it on/off with the Settings
button for access as needed.
• At any point in time you can connect a Direct mode unit to a Home
Network: Device Manager > Device Line menu > About > Connect.
Connectivity Modes
For full functionality Red Sea’s connected devices must be permanently
connected to the Internet and the aquarium set as “Online”.
In the event that you do not have an available Wi-Fi network or your
network does not have a permanent internet connection set your aquarium
as “Offline”. You can change this setting later if Internet availability status
changes. Note that your SMD must be online for this change to be registered
on the ReefBeat cloud.
In both Online and Offline modes, the ReefLEDs will provide exactly the same
performance. The differences are related to the interaction with the units, ease
of set up and making changes- specifically when multiple ReefLEDs or other
Red Sea connected devices are in use on the same aquarium.
Online (Internet) mode – full functionality
With a permanent connection to the internet, your ReefLED will have
full functionality and all ReefBeat cloud related services. This includes
real time status of your ReefLEDs in the ReefBeat homepage and
notifications if communication with one or more units has been lost or
is malfunctioning.
Offline Local Network mode – partial functionality
ReefLEDs are connected to a home network without a permanent
internet connection, and aquarium is set as Offline.
In Offline mode, your SMD will need to be connected to the same
network as your Red Sea connected devices to communicate with them.
When connected to the same network, you will see the real time status
on the homepage and have full functionality for grouped devices except

Red Sea ReefLED™

Operation
The ReefLED will run automatically according to the set schedule of
D-Programs.
Grouped ReefLEDs all work together as a single luminaire and is the
preferred mode of operation.
To enjoy all of the functionality that the ReefBeat system has to offer, the
ReefLEDs should be connected to the internet at all times.
With an active internet connection, the ReefBeat homepage will show all
of the current settings of the ReefLED group or for each ungrouped unit
individually.
Manual Operation
To temporarily override the automatic schedule, tap "Manual mode" from
the 3-dot menu of the Dashboard.
Manual mode provides direct control of all 3 channels and overrides the
current D-program while the manual page is open. Leaving the manual
page automatically returns the ReefLEDs to the schedule.
To maintain a manual setting for a period of up to one hour, set the
manual “Run Time” to the desired time. The ReefLEDs will automatically
return to the current D-Program when the Run Time expires.
Device Manager
The Device Manager is accessible from the Page menu in both the
ReefBeat homepage and the ReefLED Dashboard, and contains a list of all
of the Red Sea connected devices that are installed on each aquarium. The
devices are listed according to type and in the order in which they were
added to the aquarium. Tapping the 3-dot menu for each device opens a
list of advanced settings/functions for each ReefLED individually.
Group / Ungroup status
The grouped/ungrouped status of each ReefLED is shown in the Device
Manager.
Multiple ReefLED units that are connected to the same home network
can either be operated together as a group or as individual units. The first
ReefLED connected to the home network will automatically belong to
the LED group for that aquarium. Subsequent units will be added to the
group and receive the same settings. An individual LED can be ungrouped
or re-grouped at any time. When a unit is ungrouped, it will maintain the
same settings it had when it was grouped until changes are made. Once
added to a group, the previously ungrouped LED will automatically get the
settings of the group.
To change the status: Device Manager > Device Line menu > Group/Ungroup

Firmware Updates
From time to time you may receive a notification that a new firmware
version is available for your ReefLED. It is important to keep your ReefLED
firmware updated to ensure compatibility with updates to the ReefBeat
app.
If your ReefLED is not permanently connected to the internet, you will
need to connect it temporarily in order to update the firmware.
Device Manager > Device Line menu > About – will show the currently
installed firmware version.
From the "About" menu, tap “New” to begin the firmware update process.
Do not unplug the ReefLED while it is downloading and installing the new
software.
When the firmware update is complete, the “About” page will show the
new version as the current version together with the date and time that
the update was performed.
All of your previous settings will remain as before.
If the firmware update is not successful, the ReefLED will automatically
revert to the previous version. Repeat the process a few minutes later.
If your ReefLED does not seem to be performing correctly after the update,
disconnect and reconnect the power by the DC jack and wait for the
ReefLED to restart.
Removing a ReefLED - Temporary
When switching off or physically removing a ReefLED temporarily such as
when doing reef-scaping or other maintenance on the aquarium, set the
unit to “Out-of-service” through the Device Manager to prevent ReefBeat
from giving you notifications that communication with the unit has been
lost. When returning the unit and/or switching it back on, remember to
return its status to “In-service”. To change the status: Device Manager >
Device Line menu > In-service / Out-of-service.
Removing a ReefLED - Permanent
When permanently removing a ReefLED from an aquarium or before
resetting the unit’s memory, delete the unit from the ReefBeat app:
Device Manager > Device Line menu > Delete.
Deleting before it is switched off will prevent unnecessary notifications
that communication with the unit has been lost.
Clear ReefLED settings
To permanently remove all user settings from the memory of the ReefLED
and return it to its initial default state, perform the following steps.
Permanently remove (Delete) the specific ReefLED from ReefBeat.
Press the Settings button for about 15 seconds (until the indicator LED
shows a double blink), release the button and wait for about 5 seconds
until a second double blink of the indicator LED appears.
Disconnect and reconnect the power by the DC jack and wait for the
ReefLED to restart.
The unit will restart without any user settings and with the Wi-Fi switched
off, exactly as shipped from the factory. The unit will retain the latest
installed version of the firmware.

Red Sea ReefLED™
18
Notifications
When the ReefLED has a permanent connection to the internet, a
notification will be sent to your SMD whenever connection to the
unit is lost.
A “No communication” message could be due to a power or
internet outage, router failure or a fault with a specific connected
device.
If you have more than one Red Sea connected device and
connection to one or more (but not all) devices are lost, you will
receive a “Partial communication” message. You will then be able
to see the current status of all devices from the Device Manager.
You can set how you wish to receive some of the messages from
“Notifications” in the homepage main menu.
Overtemperature protection
The ReefLED is designed with active cooling to ensure the longevity of the
LED array.
Fan speed will vary according to the light intensity. At very low intensity
levels such as with moonlight the fan is not required. At full LED intensity
and with an ambient temperature of about 25°C/ 77°F the fan will run at
about 85% capacity. In high ambient temperature environments, the fan
speed will increase to 100% to maintain the correct working temperature
for the LED array.
If the ambient temperature is too high or airflow to the unit is restricted
the unit will automatically dim the intensity of the LEDs or shut it down
completely to prevent damage to the unit. In the event of shutdown due
to overtemperature you will need to disconnect and reconnect the power
by the DC jack to restart. Check the unit and surroundings for the cause of
the overtemperature situation.

Red Sea ReefLED™

Maintenance
For continued smooth running of the ReefLED, we recommended making
sure that it is clean, dry and free of any buildup of salt deposits on a
regular basis.
Before doing any maintenance, disconnect the unit, allow the lens to cool
down and allow it to dry completely before reconnecting.
Remove the top cover and wipe it ,as well as the heat sink and fan with a
damp cloth.
If the lens becomes contaminated with water, dust, or other particles,
clean with isopropyl alcohol.
The unit is not waterproof. Do not submerge in water or other solutions.
Apart from the cooling fan, there are no user serviceable parts inside the
unit.
Fan replacement
In the event that the fan makes an unusual mechanical noise or stops
working, try removing dust or salt deposits by cleaning as described
above. If this does not help, the fan will need to be replaced. Disassemble
and reassemble the fan as shown. Care should be taken not to touch the
surface of the LED array.
Battery replacement
The ReefLED has a back-up battery to maintain power when the unit is
disconnected from the power supply. This battery will need to be replaced
once every few years. To replace the battery, open the unit as shown.
Replace with a 3V Lithium cell Battery CR1220.
After reassembling the unit and switching it on, the internal time may
need to be reset.
Device Manager > Device Line menu > About.
Online devices will have the time updated automatically when Internet
connection is restored. Offline devices will need to have the time reset
manually. Tapping on the row will open a time setting window which will
show the current time on your SMD. Press "Set" or change the time as
needed.

Troubleshooting
A full and up to date FAQ for the ReefLED and the ReefBeat app is
available in the app (Homepage Main Menu > Help > FAQ) and on our
website.
Q.I am having trouble installing the ReefBeat app or it crashes or
does not seem to be working as described in the manual.
A. Check that your specific smart mobile device is on the list of supported
devices on our website.
Q. My smart mobile device is on the list of supported devices but
keeps crashing.
A. Uninstall and reinstall the app and sign in again with your username
and password. If this does not help, contact customer support.
Q. I've plugged in a new unit and the light is not coming on.
A. The ReefLED will only work after it has been connected to the ReefBeat
app.
Q. I'm having difficulty connecting the ReefLED to my home network.
A. Check that the ReefLED Wi-Fi is working correctly by using the “Offline
Direct Mode” option. If it does, try connecting to the hot-spot of a
mobile phone in the same room: Device Manager > Device Line menu >
About > Connect.
If neither of these options work, contact customer support. If they
do work, the problem is likely with the router signal strength or its
configuration, or it may be overloaded with devices.
• Check that the signal strength of your router is sufficient for a stable
connection exactly where the ReefLED is located. You may need to
install a suitable Wi-Fi extender closer to the aquarium.
• The router may have too many devices already connected to it.
• Your router may be configured not to allow devices like the ReefLED
to be connected. This situation is common in an office environment-
contact your IT professional.
Q. I keep getting notifications that my ReefLEDs are not connected.
A. If your network router is not permanently connected to the internet, set
your Aquarium as “Offline” My Aquariums > Device Line Menu > Offline. If
your network router is meant to be permanently connected, check the
quality of the Wi-Fi connection between the units and your router or the
stability of your internet connection.
Q. There is a small difference between the LED intensities shown on
the ReefBeat homepage and the current intensities shown on the
ReefLED Dashboard.
A. The homepage updates once per minute with the actual values as
reported by the unit. The Dashboard shows the calculated values according
to the D-program and effects. A discrepancy of a few percent between
the two readings is normal, especially during periods where the values are
constantly changing such as during sunrise and sunset.
Q. Sometimes there is a constantly varying difference between the
LED intensities shown on the ReefBeat homepage and the current
intensities shown on the ReefLED Dashboard.
A. You are likely seeing the effect of the random clouds. The homepage
updates once per minute with the actual values as reported by the
unit. The Dashboard page shows the calculated values according to the
D-program. However, it does not take into account the effect of the
random clouds which are implemented on each ReefLED individually. If
you cancel the clouds, the differences should disappear.

Q. According to the current D-Program, the LEDs should be working
but no light is on.
A. Go through the following diagnostic check list one stage at a time:
1. Check that the ReefLED power indicator LED is on. If Ok, go to #2. If it is
not on, check that the power supply indicator light is on. If Ok, go to #2.
If it is not on, check that the power outlet has power and the AC cable
is properly connected. If it is connected, the power supply will need to
be replaced.
2. Check that the ReefLED is connected to your ReefBeat app by tapping
the “Identify” function: Device Manager > Device Line Menu > Identify
The ReefLED should blink a few times. If it does, go to #3. If it does
not, disconnect and reconnect the power by the DC jack to restart. If
it still doesn't blink, try reconnecting the ReefLED to ReefBeat. If this
did not help, go through the "Clear Settings" steps (see page 17) and
reconnect. If still not working contact customer support.
3. Check that all 3 color channels are working:
ReefLED Dashboard > Page Menu > Manual. If they are, go to #4. If they
aren't, disconnect and reconnect the power by the DC jack to restart.
If still not working, try reconnecting the ReefLED to ReefBeat. If this
did not help, go through the "Clear Settings" steps (see page 17) and
reconnect. If still not working contact customer support.
4. Check that the aquarium is set up for the correct time zone:
Homepage > Main Menu > My Aquariums > Device Line Menu > Edit
Aquarium > Aquarium Time Zone. If OK, go to #5. If not, set the correct
time zone.
5. Check that the current time on the ReefLED is correct:
Device Manager > Device Line Menu > About > Current Time. If OK, go
to #6. If not, reset time then disconnect and reconnect the power by
the DC jack to restart the unit. Check the time again and if it is still not
correct, try replacing the battery.
6. If the current time was correct, disconnect and reconnect the power by
the DC jack to restart. If it was not correct, try reconnecting the ReefLED
to ReefBeat. If this did not help, go through the "Clear Settings" steps
(see page 17) and reconnect. If still not working, contact customer
support.
Q. My lights do not go on and off together.
A. Check that you have not activated the Staggered Sunrise function
which sets a delay between the ReefLED units by a few minutes.
• Check that the units are grouped. If they are ungrouped, check that
they all have the same D-program/schedule.
• Check that all units have the correct time:
Device Manager > Device Line Menu > About > Current Time.
Q. I've activated the Staggered Sunrise option but the lights do not
work in the correct order.
A. See "Staggered Sunrise" in the manual to set the lights in the correct
order.
Q. One of the color channels does not seem to be working properly.
A. Go to Manual control: ReefLED Dashboard > Page Menu > Manual.
Test all 3 channels individually and if one or more do not work, disconnect
and reconnect the power by the DC jack to restart. Recheck the channels
using the Manual control. If this did not help, go through the "Clear
Settings" steps (see page 17) and reconnect. If still not working, contact
customer support.
Q. Everything seems to be working correctly when i am home but I
am not getting any information when i am away from home.
