The Fluval Plant 4.0 LED 22W is a professional‑grade planted aquarium light that has been carefully engineered to help aquatic plants thrive while remaining simple and reassuring for the beginner aquarist. Designed for aquariums between 15–24″ (38–63 cm), this compact yet powerful unit delivers full‑spectrum illumination optimised for photosynthesis, strong root development and rich, natural plant coloration.
Full‑spectrum light for healthy plants

-
Powerful full‑spectrum output with six tailored wavelength bands supports robust plant growth, including warm white, cool white, blue and dedicated plant‑enhancing pink channels.
-
1600 lumens and approximately 7500 K colour temperature ensure bright, clean light that penetrates well through the water column, ideal for low to medium‑demand plants in small to medium aquariums.
-
A high 90 CRI (Colour Rendering Index) makes fish and plants look natural and vibrant, showcasing every shade of green and red in your aquascape.
Smart app control for beginners

-
Operated via the user‑friendly FluvalConnect mobile app (Bluetooth), allowing simple control from your smartphone or tablet.
-
Easily configure a 24‑hour lighting schedule with gradual sunrise, mid‑day, dusk and moonlight phases to gently acclimate fish and plants and avoid sudden light shocks.
-
Independent colour channel control and preset environments make it straightforward for beginners to choose plant‑focused or display‑focused lighting without needing expert technical knowledge.
Robust, water‑resistant construction

-
IP67 water‑resistant design allows safe, secure mounting directly over the water surface, reducing light loss and improving penetration into dense plant growth.
-
Durable aluminium alloy frame helps dissipate heat efficiently, promoting long service life and stable performance.
-
A high‑quality glass lens protects the LEDs from moisture and dust while ensuring clear, even light distribution across the entire tank.
Flexible installation for 15–24″ tanks

-
Designed specifically for aquariums from 38–63 cm (15–24″), ideal for nano to small community planted tanks.
-
Extendable mounting brackets and height‑adjustable risers allow easy fitting on different tank widths, lids or open‑top setups.
-
Optional suspension accessories (where available) offer further flexibility for aquascapes that require higher mounting or open‑rim styling.
Energy‑efficient and user‑friendly
-
Consumes only 22 W while delivering light intensity comparable to much higher‑wattage traditional lighting, helping to reduce long‑term energy costs.
-
Touch‑switch control on the unit allows simple on/off, dimming and blue‑light modes even without a mobile device, helpful for quick manual adjustments.
-
Ideal for beginner aquarists who want a reliable, low‑maintenance solution that can grow live plants, improve fish wellbeing and enhance the visual appeal of the aquarium.
