Chihiros C2 Pro Mini LED Review: Magnetic Nano Fixture
Chihiros has taken over the Singapore nano-tank lighting scene over the past five years on the strength of one simple fact — they sell more PAR per dollar than anyone else competing at this size. The Chihiros C2 Pro Mini is the latest entry in their ultra-compact range, replacing the older Mini A-II with a sharper spectrum, a stronger magnet, and proper Bluetooth control through the Chihiros app. This review from Gensou Aquascaping at 5 Everton Park covers PAR numbers, spectrum quality, build, and which nano tanks it actually fits.
What the C2 Pro Mini Replaces
The Mini A-II that this fixture supersedes was a beloved but ageing product — adequate spectrum, mediocre build, fixed brightness, no app control. The C2 Pro Mini keeps the magnetic mount concept but rebuilds everything around it. The casing is now anodised aluminium rather than coated steel, the LED count climbs from 12 to 18, and the app integration is properly stable on iOS and Android.
Footprint and Mounting
The fixture itself measures roughly 14 cm long, 2 cm wide and 1 cm thick — slim enough to disappear over a 30 x 30 cm cube. The mount is a magnetic ring that clamps over rimless glass up to 12 mm thick, with the LED side floating just above the water surface. There are no clips to mar the glass edge. For tanks with a glass cover slip, the fixture sits cleanly on top — the magnet is strong enough to hold even with a slip in between.
PAR and Light Output
At 100 per cent brightness, the C2 Pro Mini delivers roughly 80-95 µmol PAR at 25 cm depth directly under the centre of the fixture, dropping to 40-50 µmol at the tank corners on a 30 x 30 cm cube. That is high-light territory for a nano — sufficient for demanding stem plants, dwarf hairgrass carpets and most red-leafed species. For a 20 cm tall pico tank with shrimp, dim to 50 per cent to avoid algae issues.
Spectrum Profile
The C2 Pro Mini runs a roughly 50 per cent white, 25 per cent red, 15 per cent green, 10 per cent blue ratio. Colour temperature reads around 7500K at full output. Plant chlorophyll absorption is well-served by this profile, and the slight red emphasis brings out warm tones in Rotala and Ludwigia leaves. Compared to the Twinstar B-line’s more neutral white-dominant spectrum, the Chihiros pulls slightly warmer and more saturated.
Bluetooth App and Dimming
The Chihiros app pairs reliably and lets you set sunrise, peak and sunset ramps with brightness curves for each colour channel. A 6-8 hour photoperiod with a 60-minute ramp on either end is the usual planted-tank standard. The app remembers settings across power cuts — a real concern in older HDB blocks where breaker trips happen. Manual control via a single touch button on the fixture also works for users who avoid apps.
Pricing in Singapore
The C2 Pro Mini retails at SGD 95-130 across local shops, with Gensou and selected scaping shops at the lower end and Lazada listings from the official distributor at the higher end. That undercuts a comparable Twinstar B-line by roughly SGD 30-40 and the ONF Flat Nano by even more. The lighting category at Gensou stocks the full Chihiros nano range.
Compatible Tank Sizes
The fixture is rated for tanks 25-35 cm in length. On a 25 cm cube it covers the full footprint at usable PAR. On a 30 cm cube it covers comfortably with mild corner roll-off. On a 35 cm cube it stretches and corners drop below 30 µmol — usable for low-light setups but not enough for carpet plants. Anything over 35 cm needs a larger fixture from the C-series or the upcoming Magnetic Plus.
Build, Pros and Compromises
The anodised aluminium body runs warm but never hot — sustained 100 per cent operation hits 38-40°C casing. IP65 means splash-safe but not submersible. The cable to the power adapter is 1.8 metres with a standard SG 3-pin plug. Pros: excellent PAR per dollar, slim profile, magnetic mount, stable app, anodised build. Compromises: 35 cm tank length limit, no IP67 submersion, magnet can dislodge if knocked, Bluetooth-only with no colour temperature shift.
Sibling Products and Pair-With
The standard C2 Pro covers 40-50 cm tanks at higher PAR for SGD 130-170. The Magnetic LED Mini is the stripped-down sibling without app control for SGD 65-85. The WRGB II Slim is the premium sibling at SGD 280+ that handles 60 cm tanks with full RGB tuning. The C2 Pro Mini pairs well with a Dennerle Scapers Soil 4L base, a small CO2 system from the equipment range, and a 30 cm cube tank. For 35 cm cubes with shrimp, dim to 60 per cent.
Where to Buy in Singapore
Gensou carries the C2 Pro Mini at 5 Everton Park alongside the rest of the Chihiros range. Polyart and Iwarna stock it consistently. Carousell second-hand units appear at SGD 60-80, often from scapers upgrading — inspect for water damage on the LED side and confirm the app pairs before buying.
