Red Sea’s ReefLED lighting systems are designed to simplify reef aquarium lighting while delivering the spectrum and intensity corals need to thrive. Unlike many reef lights that require complex manual programming, ReefLED fixtures integrate seamlessly with the ReefBeat app, allowing you to control schedules, intensity, acclimation settings, moonlight cycles, and multiple devices from your smartphone.
Whether you’ve just purchased your first ReefLED 50, ReefLED 90, or ReefLED 160S, proper setup and programming are essential for achieving healthy coral growth, vibrant colours, and a natural day-night cycle.
In this guide, we’ll walk you through the entire process of installing your ReefLED, connecting it to ReefBeat, and creating the ideal lighting schedule for your reef aquarium.
Why Use the ReefBeat App?
ReefBeat is Red Sea’s smart aquarium control platform.
It allows you to manage:
- ReefLED lighting
- ReefWave circulation pumps
- ReefDose dosing systems
- ReefRun equipment
- Multiple aquariums from one app
Benefits include:
- Wireless control
- Custom schedules
- Sunrise and sunset simulation
- Acclimation mode
- Cloud connectivity
- Notifications and alerts
- Easy firmware updates
For most users, ReefBeat eliminates the need for external timers or complex controllers.
Before You Begin
Before installing your ReefLED, ensure you have:
- ReefLED fixture
- Mounting arm or suspension kit
- Power supply
- Smartphone or tablet
- ReefBeat app installed
- Active Wi-Fi connection
Wi-Fi Requirements
ReefLED fixtures use:
2.4GHz Wi-Fi networks
They do not connect directly to 5GHz-only networks.
If your router combines both frequencies, ensure your phone is connected to a compatible network during setup.
Step 1: Install the ReefLED Fixture
Begin by mounting the light securely above the aquarium.
Mounting Arm Installation
If using a Red Sea mounting arm:
- Attach the bracket to the aquarium.
- Secure the arm according to the instructions.
- Position the light centrally over the aquarium.
Suspension Kit Installation
If hanging the fixture:
- Secure ceiling anchors.
- Attach suspension cables.
- Adjust height evenly.
Recommended Mounting Heights
For most aquariums:
|
Model |
Recommended Height |
|---|---|
|
ReefLED 50 |
20–25cm above water |
|
ReefLED 90 |
20–30cm above water |
|
ReefLED 160S |
25–35cm above water |
Proper height helps maximise coverage and minimise shadowing.
Step 2: Download and Install ReefBeat
Download ReefBeat from:
- Apple App Store
- Google Play Store
After installation:
- Create a ReefBeat account.
- Verify your email address.
- Log in.
Using a single account allows access across multiple devices.
Step 3: Power On the ReefLED
Connect the power supply and switch on the fixture.
The light will enter pairing mode when powered for the first time.
If pairing mode doesn’t start automatically, follow the reset procedure outlined in the user manual.
Step 4: Add the Light to ReefBeat
Within ReefBeat:
- Tap Add Device
- Select ReefLED
- Follow on-screen instructions
The app will:
- Detect the fixture
- Connect it to your Wi-Fi network
- Register the device
This process usually takes only a few minutes.
Step 5: Update Firmware
After connection, ReefBeat may prompt you to install firmware updates.
Firmware updates often improve:
- Stability
- Connectivity
- Features
- Performance
Always allow updates to complete fully.
Avoid:
- Closing the app
- Disconnecting Wi-Fi
- Powering off the light
during the update process.
Understanding ReefLED Channels
Unlike traditional multi-channel reef lights, ReefLED uses a simplified approach.
Reef-Spec Blue
The primary lighting channel.
Provides:
- Coral growth support
- Photosynthesis
- Fluorescence
Most reef systems operate with this channel at or near maximum output.
White Channel
Adds:
- Natural daylight appearance
- Colour balance
- Improved viewing
Typically used at lower levels than blue.
Moonlight
Provides subtle night-time illumination and lunar simulation.
Step 6: Choose a Lighting Preset
ReefBeat offers several preset options.
Coral Growth
Designed to maximise:
- Growth rates
- Photosynthetic efficiency
Excellent for SPS-dominated systems.
Coral Colours
Optimised for:
- Fluorescence
- Visual appearance
- Mixed reefs
Popular among hobbyists seeking vibrant coral colours.
Custom Schedule
Allows complete control over:
- Intensity
- Timing
- Sunrise and sunset duration
Most users start with a preset and make minor adjustments over time.
Step 7: Configure Your Photoperiod
A typical reef aquarium lighting schedule includes:
Sunrise
8:00 AM – 10:00 AM
Gradual intensity increase.
Peak Lighting
10:00 AM – 6:00 PM
Maximum intensity period.
Sunset
6:00 PM – 8:00 PM
Gradual intensity reduction.
Moonlight
Optional after sunset.
This creates a more natural environment for fish and corals.
Recommended Beginner Settings
For a mixed reef:
Reef-Spec Blue
100%
White
20–25%
Moonlight
1–3%
Total Photoperiod
10–12 hours
These settings provide an excellent starting point for most reef aquariums.
Step 8: Use Acclimation Mode
One of the most valuable ReefBeat features is Acclimation Mode.
Why Acclimation Matters
Corals can become stressed when exposed to stronger lighting too quickly.
Potential symptoms include:
- Bleaching
- Reduced polyp extension
- Colour loss
When to Use Acclimation
- Installing a new ReefLED
- Upgrading from older lighting
- Adding new corals
- Increasing intensity significantly
Recommended Acclimation Period
|
Situation |
Duration |
|---|---|
|
New lighting installation |
4–6 weeks |
|
New corals |
2–4 weeks |
|
SPS corals |
4–6 weeks |
The app automatically increases intensity gradually during this period.
Step 9: Program Moonlight
Moonlight creates a realistic nocturnal environment.
Benefits include:
- Natural fish behaviour
- Night-time viewing
- Lunar cycle simulation
Keep moonlight intensity low.
Too much night-time light can disrupt fish and coral rhythms.
Step 10: Configure Multiple ReefLED Fixtures
Larger aquariums often require multiple lights.
ReefBeat allows:
- Group control
- Synchronised schedules
- Individual fixture adjustments
This ensures consistent lighting across the entire aquarium.
Example ReefLED Setups
Nano Reef (Up to 60cm)
- One ReefLED 50
Mixed Reef (90cm)
- Two ReefLED 90s
SPS Reef (120cm)
- Two or three ReefLED 160S fixtures
Large Display Reef (150cm+)
- Three to four ReefLED 160S fixtures
Proper fixture spacing helps eliminate shadows and improve coverage.
Monitoring Coral Response
After programming your lighting:
Watch for:
Positive Signs
- Strong polyp extension
- Vibrant colouration
- New growth tips
- Healthy tissue
Warning Signs
- Bleaching
- Excessive algae
- Tissue recession
- Coral retraction
Adjust intensity gradually if required.
Common Programming Mistakes
Running White Too High
Can increase algae growth and reduce fluorescence.
Skipping Acclimation
One of the most common causes of coral stress.
Frequent Schedule Changes
Corals prefer consistency.
Excessively Long Photoperiods
More light does not always equal better growth.
Troubleshooting Connectivity Issues
If the light won’t connect:
Check Wi-Fi
Ensure:
- 2.4GHz network is available
- Signal strength is adequate
Restart Devices
Power cycle:
- ReefLED
- Router
- Smartphone
Update ReefBeat
Ensure the latest app version is installed.
Reset the Fixture
If problems persist, remove the device and reconnect it.
Most connection issues are resolved through these steps.
Maintaining Your ReefLED System
For long-term reliability:
Monthly
- Inspect mounting hardware
- Check cable routing
- Remove dust from vents
Quarterly
- Verify schedules
- Check firmware updates
Annually
- Review coral placement and PAR distribution
Proper maintenance helps ensure consistent performance.
