Fluval REEF 4.0 Aquarium LED Light | *NEW* Full Review
fluvalaquatics.com/uk/shop/lighting/saltwater-led/reef-4-0
The German-engineered Fluval Reef 4.0 LED doesn’t just illuminate your saltwater aquarium, it transforms it. With its critical actinic range, this full-spectrum lighting system gives your corals exactly what they need to photosynthesize, grow, and show off their most vibrant colors. The best part? You can control everything from your smartphone. The FluvalConnect app puts you in charge of independent color channels, 24-hour lighting cycles, and even special effects. You can choose from several pre-set environments or create your own perfect underwater world. Built to last, the Reef 4.0 LED features advanced IP67-rated protection against water, moisture, and dust, along with a glass lens delivering crystal-clear illumination that won’t degrade over time. Installation is a breeze, whether you prefer extendable brackets, adjustable risers, or a suspended display, you’ve got options to mount the light exactly where you need it.
