The aquascaper's default: a bright, individually-tuned full-spectrum RGB fixture with app control and enough PAR to run a demanding, CO2-injected carpet on a 60 cm tank.

👍 Pros
- High PAR with individually-addressable R, G, B and white channels — enough to grow carpets and red plants
- My Chihiros app gives you sunrise/sunset ramps, custom spectrum and a built-in timer, no separate plug needed
- RGB mix renders reds and greens far more vividly than a white-only fixture
- Slim aluminium body and mounting legs look the part over an open-top scape
👎 Cons
- Enough light to grow serious algae if you run it without CO2 and ferts
- App and Bluetooth pairing can be fiddly on first setup
- Premium price for what is, at heart, a 60 cm fixture
Why aquascapers reach for this one
The Chihiros WRGB II Pro 60 earns its place because it does the two things a high-tech planted tank needs: it puts out enough PAR to grow demanding carpets and red stems, and it lets you shape the spectrum channel by channel. The red, green, blue and white LEDs are individually addressable through the My Chihiros app, so you can dial in a mix that favours plant growth while making your scape genuinely pop — the RGB rendition of reds and greens is where cheaper white-only bars fall flat.
The catch: light writes cheques your CO2 has to cash
This is a lot of light, and that is a double-edged sword. Run it flat-out over a tank with no CO2 and no dosing, and you are effectively fertilising algae instead of plants. The rule is simple: match your light to the rest of the system. If you are injecting CO2 (see our CO2 systems hub) and dosing an all-in-one from our plant fertilizers guide, you can push it. If not, dim it and keep a tight 6–8 hour photoperiod on the built-in timer.
How it fits our other picks
If this is more light — and more money — than your tank needs, the app-controlled Fluval Plant 3.0 is a gentler, still-excellent planted fixture. For the full line-up and the low-tech vs high-tech question explained, see our aquarium lighting hub, and match the light to your tank on the aquariums page.
The reference light for a serious 60 cm aquascape: high PAR, genuinely useful app control and colour rendition that white-only fixtures cannot match. Overkill for a low-tech tank, perfect for a high-tech one.
Chihiros WRGB II Pro 60 — frequently asked questions
Is the WRGB II Pro too much light without CO2?
For most people, yes. It can push very high PAR, and light that outruns your CO2 and nutrients is the fastest route to algae. If you run low-tech (no CO2), dim it to 40–60% and keep the photoperiod short until the tank settles.
How long should I run it each day?
Start at a 6–8 hour photoperiod on the app's built-in timer. Six hours is a sensible starting point for a new tank; extend towards eight only once plants are established and algae is under control. Consistency matters more than duration.
Does the RGB actually help plants, or is it just for looks?
Both. Plants mainly use red and blue, so the tunable channels let you favour growth, while the green channel and overall RGB mix massively improve how reds and greens read to your eye — colour rendition, not just raw output.
