Product Description
Fluval Reef 4.0 LED Aquarium Light - 35-49 Inch
The Fluval Reef 4.0 LED Aquarium Light - 35-49 Inch is a 46W smart reef LED built for larger saltwater aquariums that need full-spectrum coral lighting, strong actinic colour, app-controlled scheduling, and broad 110 degree light spread.
Reef 4.0 Lighting for Larger Marine Displays
This 35-49 inch Reef 4.0 model gives larger reef aquariums a controlled lighting platform with enough output and spread for broader coral displays. It combines reef-focused spectrum, customizable colour channels, and durable construction for hobbyists who want a clean smart lighting solution without adding a separate controller.
Coral Colour, Growth, and Coverage Features
- Maximized coral spectrum: Seven LED colour bands provide full-spectrum reef lighting with the actinic range needed for coral photosynthesis and fluorescence.
- Customizable channel output: FluvalConnect lets you fine-tune colour intensity for daylight viewing, deep blue reef presentation, or balanced coral growth support.
- Programmable 24-hour cycle: Adjust sunrise, midday, dusk, and night stages to mimic natural reef lighting transitions.
- Preset reef environments: Built-in profiles give a quick starting point for common marine display preferences.
- Wide 110 degree dispersion: Each LED casts broad light to help illuminate the aquarium evenly across coral placement zones.
- High-efficiency 25000K marine tone: Produces the crisp blue-white appearance commonly preferred for reef aquariums.
- IP67 rated design: Water, moisture, and dust protection with a glass lens helps protect the fixture in saltwater conditions.
- Adjustable riser brackets: Included mounting hardware supports clean positioning over the aquarium for improved access and spread.

Larger Reef Compatibility Notes
This 46W Reef 4.0 fixture is a strong fit for larger saltwater aquariums where broad coverage and adjustable spectrum are key. For light-sensitive corals, newly added frags, or tanks switching from a weaker fixture, use a reduced starting program and increase output gradually.
