Choosing a line
- Plant 4.0 - full spectrum output for planted freshwater tanks, with ramping and custom cycles.
- Plant Pro - the high output planted option, built on dual-angle lightboards with a 90 CRI rating and the highest PAR in the range.
- Reef 4.0 - marine spectrum aimed at coral growth and coloration.
- Aquasky 3.0 - everyday freshwater lighting at the entry point of the range.
Sizing and mounting
Every fixture in the range is sold by span rather than by a single length. The 15-24, 23-35, 35-49 and 46-61 inch models all sit on extendable brackets that rest across the top of the aquarium, so one size covers a band of tank widths. That makes the outside width of the tank the number that matters, not the nominal gallon rating. Nano models are fixed-size units for small aquariums, and the Flex replacement lights are matched to a specific aquarium kit rather than to a width.
App control
Plant 4.0, Reef 4.0 and Aquasky 3.0 fixtures connect over Bluetooth to the FluvalSmart app, which handles intensity, spectrum, sunrise and sunset effects and scheduled light cycles. The Plant Pro runs on the newer FluvalConnect app over Bluetooth Mesh, with saved profiles for different aquascapes. The two apps are not interchangeable, so check which one a fixture uses before adding a second light to an existing setup.
