Other mounting options like the arm kit or pendant solution are available separately. The arm kit can be adjusted for tank widths of 12-25cm and heights of 20-35cm, suitable for rimless or rimmed tanks. The pendant solution allows hanging multiple RL90 units over larger tanks.

4.2 Power Connection
Connect each RL90 light unit to its dedicated power supply and then to a power outlet. Ensure all connections are secure before powering on the units.
5. Operating Instructions: Smart App Control
The PopBloom RL90 lights are controlled via a smart application, allowing for flexible programming and adjustment.

6. Light Performance and Features
6.1 Full Spectrum Output
The RL90 provides a full color spectrum, including popular blue, red, green, and Violet+UV wavelengths. This spectrum is designed to promote optimal coral growth and enhance coloration, creating a natural shimmer effect in the aquarium.


6.2 PAR Value and Distribution
The RL90 is scientifically engineered to balance PAR/Lumen output and coverage, suitable for tanks up to 30 inches deep. It provides ideal PAR values throughout the aquarium, minimizing hotspots and ensuring uniform illumination for coral growth.


6.3 Glare-proof Recessed Lens and HD Power
The RL90 features a glare-proof recessed lens design, providing homogeneous light with a gentle shimmer. This design helps achieve a balance of power and spread, reaching up to 80cm deep with high uniformity. The HD Power feature dynamically adjusts power across channels, borrowing power from unused colors to provide the most vivid spectrum.


7. Maintenance
Regular maintenance ensures the longevity and optimal performance of your PopBloom RL90 LED aquarium light.
- Cleaning: Periodically wipe the light unit and lens with a soft, damp cloth to remove salt creep, dust, and water spots. Ensure the unit is unplugged before cleaning. Do not use abrasive cleaners or solvents.
- Cooling System: The RL90 uses a smart cooling fan and cold forging heat sink. Ensure the fan vents are not obstructed to maintain efficient cooling and extend LED lifespan.
- Power Connections: Regularly check power plugs and connections for any signs of wear or corrosion.
