Fluval Reef 4.0 LED Aquarium Light - 15-24 Inch
The Fluval Reef 4.0 LED Aquarium Light - 15-24 Inch is a smart saltwater aquarium light designed for compact reef systems that need full-spectrum coral lighting, critical actinic output, FluvalConnect app control, and a sealed IP67-rated body for marine use.
Reef 4.0 Lighting for Compact Marine Aquariums
This 22W Reef 4.0 model is built for saltwater aquariums from 15 to 24 inches wide and gives smaller reef displays a controlled coral-focused spectrum. It is suited to nano and compact marine systems where colour, fluorescence, coral health, and reliable app scheduling are all important.
Coral Spectrum and Smart Reef Control
- Full-spectrum reef output: Seven LED colour bands help support coral growth, colour, and health while creating a crisp marine viewing appearance.
- Critical actinic range: Dedicated violet and blue wavelengths help enhance coral fluorescence and support photosynthetic reef organisms.
- Independent colour channels: FluvalConnect lets you adjust colour balance and intensity to match the look and needs of the reef display.
- Programmable 24-hour cycle: Create sunrise, midday, dusk, and night phases to mimic natural sun and moon transitions.
- Preset reef environments: Convenient profiles provide a practical starting point for common marine lighting styles.
- Wide 110 degree LED coverage: Each LED casts broad light to help provide even illumination through the aquarium.
- IP67 protected fixture: Advanced water, moisture, and dust protection with a glass lens supports dependable saltwater aquarium use.
- Flexible mounting design: Extendable riser brackets help position the fixture cleanly over compatible aquarium widths.

Compact Reef Application Notes
This 15-24 inch Reef 4.0 is best suited to smaller reef aquariums where controlled full-spectrum output and actinic-heavy presentation are needed. Begin with moderate intensity when changing lights or adding corals, then raise output gradually while monitoring coral extension, colour, and algae response.

Mount the fixture over an aquarium within the 15 to 24 inch range, connect the power supply, and pair it with FluvalConnect. Use a gentle ramping schedule when corals are adapting to the new light, then adjust channels and intensity slowly based on coral response.
