Aquarium LED light Fluval Plant 4.0 32W for 58.9–88.9 cm tanks, Bluetooth control

Fluval Plant 4.0 is a 32W LED aquarium light engineered for freshwater planted tanks with widths from 58.9 to 88.9 cm. The fixture delivers a spectrum tuned for aquatic plants, supporting photosynthesis and healthy growth while providing flexible control over intensity and colour balance. Integrated Bluetooth connectivity and a companion app enable easy programming of daily cycles and customised spectral output to match different plant requirements and visual preferences.

Advantages

The light offers a plant-focused spectral output that emphasises the wavelengths most effective for photosynthesis and plant pigmentation. Adjustable intensity and spectrum let you tailor lighting conditions for low- to high-light plant species. Bluetooth control and an intuitive app simplify schedule programming, scene creation and fine-tuning without requiring external controllers. The slim profile and mounting options provide a secure fit across the compatible tank widths while minimising visual obstruction to the aquarium view.

Suitable for

• Freshwater planted aquariums between 58.9 and 88.9 cm wide
• Tank setups requiring programmable day/night lighting cycles
• Aquarists who need spectrum and intensity control for different plant species
• Display aquaria where a low-profile LED fixture is preferred

How to use

Install the fixture according to the supplied mounting instructions so it spans the aquarium at the correct width. Connect the unit to a power source and pair it with the manufacturer’s Bluetooth app on a compatible smartphone or tablet. Use the app to set up daily lighting schedules, adjust intensity and tweak the spectrum based on plant requirements. Monitor plant response and adjust light duration or intensity incrementally to avoid algae outbreaks when establishing new settings.

Usage recommendations

Begin with moderate intensity and a daily photoperiod typical for planted tanks (for example, 6–8 hours), then increase gradually if plants show strong growth and no sign of excessive algae. Use the programmable spectrum options to provide cooler light during acclimation and richer red/blue balance for active growth stages. Regularly check plant health and water parameters to correlate lighting changes with biological response.
