4. Setup and Installation
Follow these steps to properly install your PopBloom RL90 LED Aquarium Light system:
- Unpack Components: Carefully remove all items from the packaging and ensure all parts listed in Section 2 are present and undamaged.
- Assemble Hang Kit: Attach the hanging wires to the designated points on each RL90 light panel. Refer to the hang kit instructions for specific assembly details.
- Position Lights: Suspend the light panels above your aquarium using the hang kits. Ensure the lights are securely mounted and positioned to provide even coverage over your tank. For a 72-96 inch marine aquarium, 4 lights are recommended.
- Connect Power: Connect each RL90 light panel to its respective DC power adapter, then plug the power adapters into a suitable power outlet.
- Daisy Chain Connection (Optional): The RL90 supports real daisy chain functionality, allowing one system to control up to 10 panels simultaneously. Connect the lights using appropriate daisy chain cables (sold separately if not included) if you wish to control multiple units from a single point.

5.2 Channel Programming
The RL90 has 4 independently programmable channels, adjustable from 1% to 100% intensity.
- Channel 1 (White): 10W 8000K White, designed for deep penetration.
- Channel 2 (Moon UV&Blue): 5W Moon UV&Blue, for simulating natural moonlighting.
- Channel 3 (Reef Blue): 65W Reef Blue, for deep penetration and optimal growth of SPS/LPS corals.
- Channel 4 (Cyan Blue): 10W Cyan Blue, for enhanced coloration.
5.3 Programming Modes
The app offers flexible programming options:
- Program Mode: Set up to 8 time-points with automatic ramp-up and ramp-down for each channel, simulating natural day-night cycles.
- DIY Mode: Customize moon settings, time offsets, and limit output for advanced control.
6. Light Distribution and Lens Design
The RL90 is engineered for optimal light delivery and visual comfort.

Figure 7: Illustration of the Glare-Proof Recessed Lens. This design ensures homogeneous light with a gentle shimmer, providing a balanced power and spread, and reaching depths of up to 80cm with high uniformity, unlike individual lenses that can cause non-uniform illumination.
7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your RL90 LED Aquarium Light.
- Cleaning: Periodically wipe the light panels and lenses with a soft, dry cloth to remove dust and salt creep. Ensure the light is unplugged before cleaning. Do not use abrasive cleaners or solvents.
- Fan Inspection: Check the cooling fans for any obstructions or excessive dust buildup. Clean gently with compressed air if necessary to maintain efficient heat dissipation.
- Cable Check: Inspect power cords and daisy chain cables for any signs of wear or damage. Replace damaged cables immediately.
8. Troubleshooting
If you encounter issues with your RL90 light, refer to the following common solutions:
- Light Not Turning On:
