Fluval Reef 4.0 LED Aquarium Light - 23-35 Inch
The Fluval Reef 4.0 LED Aquarium Light - 23-35 Inch is a 32W app-controlled saltwater LED fixture for medium reef aquariums, combining seven-band full-spectrum coral lighting, actinic output, preset environments, and IP67-rated protection.
Reef 4.0 Control for Medium Saltwater Tanks
This Reef 4.0 size fits aquariums from 23 to 35 inches wide and provides a strong balance of coral-focused spectrum, fluorescence, and app-based programming. It is a practical fit for medium marine displays where growth support, visual pop, and day-to-night control all need to come from one streamlined fixture.
Full-Spectrum Coral Lighting Features
- Seven unique LED colour bands: Provides reef-focused output to help optimize coral growth, colour, and health.
- Actinic-heavy spectrum: 400nm, 420nm, 440nm, 460nm, and 480nm channels help drive coral fluorescence and marine colour.
- FluvalConnect app control: Adjust independent channels, intensity, presets, and timing from a mobile device.
- 24-hour reef cycle: Program sunrise, midday, dusk, and night settings to mimic natural sun and moon transitions.
- Preset environments: Choose convenient aquarium profiles as a starting point before customizing the final schedule.
- Wide 110 degree light spread: Helps reduce harsh spotlighting and provides more even reef illumination.
- IP67 protection: Advanced moisture, water, and dust resistance with a glass lens supports reliable use above saltwater aquariums.
- Clean adjustable mounting: Extendable riser brackets help position the fixture for coverage, access, and appearance.

Medium Reef Application Notes
This Reef 4.0 model is suited to medium saltwater aquariums where coral colour and full-spectrum control matter. When replacing another fixture, acclimate corals slowly by starting with lower intensity and shorter peak periods before increasing output over time.
