Product Description
Fluval Reef 4.0 LED Aquarium Light - 46-61 Inch
The Fluval Reef 4.0 LED Aquarium Light - 46-61 Inch is the largest Reef 4.0 strip fixture, delivering full-spectrum app-controlled saltwater lighting for long marine and reef aquariums that need broad coverage, actinic intensity, and refined day-to-night programming.
Full-Length Reef 4.0 Coverage for Long Tanks
This 59W Reef 4.0 light fits aquariums from 46.25 to 61 inches wide and is designed for larger reef displays where coverage consistency is critical. Its full-spectrum coral output, FluvalConnect app control, and wide 110 degree LED spread make it a clean lighting solution for long saltwater aquariums with a range of coral placement zones.
Large Reef Spectrum and Smart Control
- Seven-band coral spectrum: Combines white, violet, blue, cyan, and pink channels to support coral growth, colour, and health.
- Critical actinic support: Dedicated short-wavelength channels help fuel coral fluorescence and the blue-heavy reef look many marine hobbyists prefer.
- Independent FluvalConnect channels: Fine-tune spectrum and intensity from a mobile device to match livestock needs and display preference.
- 24-hour light cycle: Program sunrise, midday, dusk, and night settings for smoother coral acclimation and natural daily transitions.
- Preset reef profiles: Built-in environments give a fast starting point for common saltwater lighting styles.
- Wide light dispersion: 110 degree LED output helps improve spread across longer aquariums and reduce harsh spotlighting.
- IP67 protected construction: Water, moisture, and dust protection with a glass lens supports long-term performance around saltwater humidity and splash risk.
- Clean adjustable mounting: Extendable riser brackets help position the light neatly over compatible long aquariums.

Long Reef Aquarium Application Notes
The 46-61 inch Reef 4.0 is best used where broad reef lighting, app-controlled spectrum, and full-length coverage are priorities. Acclimate corals carefully after installation, especially when replacing older or lower-output lighting, by beginning with reduced intensity and extending the peak period gradually.
