Product Description
Fluval Reef 4.0 Nano LED Aquarium Light
The Fluval Reef 4.0 Nano LED Aquarium Light is a compact 25W smart saltwater LED made for nano and desktop reef aquariums, delivering full-spectrum coral lighting, strong actinic colour, FluvalConnect app control, and adjustable positioning from a small square fixture.
Nano Reef 4.0 Lighting for Small Marine Displays
This Reef 4.0 Nano fixture is designed for compact reef aquariums where a full strip light is not practical. Its small 6 inch square body delivers focused output for nano coral layouts, desktop saltwater systems, and small reef displays that need serious colour control without oversized hardware.
Compact Coral Spectrum and App Control
- Full-spectrum nano reef output: Designed to support coral growth, colour, and health in smaller saltwater aquariums.
- Critical actinic range: Blue and violet spectrum support coral fluorescence and the deep marine colour response reef keepers want.
- FluvalConnect app control: Adjust independent colour channels, intensity, presets, and lighting schedules from a mobile device.
- Programmable 24-hour cycle: Create smoother sunrise, midday, dusk, and night transitions for a more stable nano reef presentation.
- Preset reef environments: Built-in profiles provide simple starting points before custom tuning.
- Adjustable positioning: The nano mounting design allows the light to move up, down, forward, backward, or side to side for better placement over coral zones.
- IP67 protected construction: Water, moisture, and dust protection with a glass lens helps protect the fixture in saltwater aquarium environments.
- Small high-output footprint: Delivers reef-focused lighting from a compact fixture that keeps nano aquariums clean and uncluttered.

Nano Reef Application Notes
Nano reef aquariums react quickly to lighting changes, so start with reduced output when installing the Reef 4.0 Nano or adding new corals. Adjust intensity and spectrum gradually while watching coral extension, colour, and algae growth in the smaller water volume.
