Aquarium LED light Fluval Sea LED Marine 3.0, 115–145 cm, 59 W

Fluval Sea LED Marine 3.0 is a dedicated aquarium LED lighting unit engineered for saltwater tanks with a length range of 115–145 cm and a power consumption of 59 W. The fixture provides a tailored light spectrum and adjustable intensity suitable for reef displays and marine fishkeeping, delivering uniform illumination across the aquarium surface while minimizing hot spots and glare. Designed to mount above the tank, the unit supports visual clarity of corals and fish while maintaining reef-appropriate light conditions.

Advantages

The light integrates multiple LED channels to reproduce a marine-compatible spectrum that promotes coral coloration and natural appearance of marine life. It offers controllable intensity and spectrum adjustment to match different coral and fish requirements, enabling customized day-night cycles and color balance. The fixture’s form factor and mounting options allow even light distribution and reduce shadows, improving viewing angles without intruding into the water. Energy-efficient operation at 59 W provides adequate output with relatively low power consumption for its coverage range.

Suitable for

• Marine reef aquariums with tank lengths between 115 cm and 145 cm
• Mixed reef systems containing photosynthetic corals and marine fish
• Display tanks where uniform illumination and color rendition are important
• Setups requiring programmable light cycles and spectrum control

Key specifications

• Recommended tank length: 115–145 cm
• Power consumption: 59 W
• Marine-optimized LED spectrum suitable for corals and marine fish
• Adjustable intensity and spectrum control for day-night cycles and coral needs
• Above-tank mounting for uniform light distribution

How to use

Install the fixture above the aquarium following the manufacturer’s mounting guidelines to ensure correct distance and stability. Configure the light schedule and spectrum settings to simulate natural daylight and acclimate corals gradually by starting at lower intensity and increasing over several days. Monitor coral response and adjust intensity or spectrum as needed to prevent bleaching or stress. Regularly clean the fixture surface and check mounting hardware to maintain consistent illumination and secure positioning.

Usage recommendations

Use progressive acclimation for sensitive corals, begin with conservative intensity settings and increase slowly over one to two weeks. Combine spectrum tuning with appropriate water parameters and flow to support coral health. Position the fixture to avoid direct glare on viewing areas and ensure even coverage across the tank.
