Fluval Plant 3.0 LED (15-24 in)
$149.99
The best planted light here: a full spectrum, app-controlled fixture with strong output that supports demanding plants, from low-light Anubias to carpets. Programmable, waterproof, and the standard the others are measured against.
Pros
- Full spectrum across six wavebands with strong output — bright, even coverage that supports demanding plants
- Enough output to grow carpet plants with CO2, high light when you want it, and dimmable for algae control when you do not
- App control (Bluetooth) with a programmable 24-hour cycle and smooth ramp up and down
- Waterproof housing with extendable brackets and, per Fluval, a 3-year warranty
Cons
- Three to four times the price of a solid budget light
- The Bluetooth app can be fiddly to pair and program

Alternatives
$39.99 · 90 / 100A
The value pick nearly everyone starts with: a full spectrum LED with sunrise/sunset and excellent colour rendering (CRI 91), enough for low-to-medium light plants. No app — just a cheap, well-proven light.
$50.34 · 87 / 100A
The best light if you do not want an app: a full spectrum fixture with a genuine built-in timer, a 24/7 sunrise-to-moonlight cycle and a DIY mode — programmable from the unit itself, at a budget price.
$65.99 · 85 / 100A−
The RGB upgrade: an adjustable-spectrum light with a proper controller for ramp up and down and a programmable schedule. This size suits larger tanks, and the tunable spectrum lets red plants colour up.
