4. Installation (Arm Mounting)
The RL90 light comes with an adjustable arm mounting kit for easy installation on most rimmed or rimless tanks.
4.1 Arm Mounting Kit Components

Figure 3: Detailed diagram of the arm mounting kit. The adjustable length is 12-25cm, and the adjustable height is 20-35cm. Various mounting options for horizontal, rimless, and rimmed tanks are shown.
4.2 Installation Steps
- Assemble the arm mounting kit according to the diagram, ensuring all screws are securely tightened.
- Attach the mounting bracket to your aquarium tank. The kit supports various tank rim thicknesses (e.g., 2cm/0.8" and 4cm/1.6").
- Adjust the arm's length and height to position the light unit over your tank at the desired distance from the water surface.
- Securely attach the RL90 light unit to the arm mount.
- Connect the DC power adaptor to the light unit and then plug the power cord into a suitable electrical outlet.
5. Smart-APP Control Setup
The RL90 light system is controlled via a smart application. Ensure you have a 2.4GHz Wi-Fi network available, as 5GHz networks are not supported.
5.1 App Download
Download the "Smart Life" app from your smartphone's app store.

5.2 Wi-Fi Connection
- Ensure your smartphone is connected to a 2.4GHz Wi-Fi network.
- Open the Smart Life app and register/log in.
- Follow the in-app instructions to add a new device. The light should enter pairing mode automatically when first powered on. If not, consult the app for specific reset instructions for the device.
- Once connected, you can control the light from anywhere with an internet connection.
6. Operating the Light (APP Functions)
The Smart Life app provides extensive control over your RL90 light, including channel programming, natural simulations, and group control.
6.1 Control Methods Comparison

6.2 Channel Programming
The RL90 features 4 independently programmable channels, adjustable from 1% to 100% brightness. You can set up to 8 time-points for each channel with auto ramp-up and ramp-down functions.
- Channel 1: 10W 8000K White, for deep penetration.
- Channel 2: 5W Moon UV&Blue, for simulating natural moonlighting.
- Channel 3: 65W Reef Blue, for deep penetration and optimal coral (SPS/LPS) growth.
- Channel 4: 10W Cyan Blue.
6.3 Natural Simulation
The app allows for natural simulations including sunrise, sunset, lunar cycles, and four seasons. These features help create a dynamic and natural environment for your aquarium inhabitants.

6.4 Group Control (Daisy Chain)
The RL90 supports real daisy chain functionality, allowing one smart-APP system to control up to 10 light panels simultaneously. This is ideal for larger tanks requiring multiple light units.

7. Technical Specifications & Performance
7.1 Light Output and Coverage
The RL90 features a 90W LED array, providing approximately 500 PAR at the water surface and 150 PAR at 60cm depth. It is recommended for 40-60cm (16-24 inch) hard and soft coral SPS/LPS tanks.

Figure 8: RL90 light specifications and tank size recommendations. For larger tanks, multiple RL90 units are suggested.
7.2 Blue Spectrum Optimization
The RL90 is optimized for a blue spectrum, beneficial for SPS and LPS corals. The homogeneous light distribution covers the tank effectively.

7.3 Glare-proof Recessed Lens
The light features a glare-proof recessed lens design, ensuring homogeneous light with gentle shimmer. This design achieves over 90% optical efficiency and provides a diffuse exit surface for improved color blending, reaching depths of up to 80cm.

7.4 Efficient Cooling System
The RL90 incorporates quality cold forging heat sinks and smart cooling fans. This efficient cooling system extends the lifespan of the LEDs and operates quietly, contributing to 15% energy savings.
8. Maintenance
Regular maintenance ensures optimal performance and longevity of your RL90 LED Aquarium Light.
- Cleaning: Periodically clean the light unit's exterior and lens with a soft, dry cloth. Ensure the light is unplugged before cleaning. Avoid using harsh chemicals or abrasive materials.
- Fan Check: Ensure the cooling fans are free from dust and debris to maintain efficient heat dissipation. Do not obstruct the fan vents.
- Cable Inspection: Regularly check power cords and connections for any signs of wear or damage. Replace any damaged components immediately.
9. Troubleshooting
If you encounter issues with your RL90 light, refer to the following common problems and solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Light does not turn on | No power, faulty connection, damaged power supply. | Check power cord and adapter connections. Ensure the outlet is functional. Verify the power supply is working. |
| Cannot connect to Wi-Fi / App control not working | Incorrect Wi-Fi band, weak signal, incorrect pairing process. | Ensure your router is broadcasting a 2.4GHz Wi-Fi signal. Move the light closer to the router. Re-attempt the pairing process as per app instructions. Contact support if using a WiFi6 router for specific setup guidance. |
| Light is overheating | Obstructed ventilation, fan malfunction. | Ensure nothing is blocking the air vents. Clean any dust from the fans. If overheating persists, discontinue use and contact support. |
| Inconsistent light output | App programming error, loose connection. | Review your app programming schedule. Check all physical connections to the light unit. |
