Faven Lighting 120W Dimmable Under-Canopy LED Bar at 46 Inches
The Faven R8 is a 120W dimmable under-canopy LED bar at 46 in long. It runs an 80% red spectrum tuned for inter-canopy use. PPF reaches 340 µmol/s at 2.9 µmol/J PPE. Voltage options cover 120V, 240V, or 277V on cords sold separately. The bubbled-lens diffuser spreads light evenly under the upper canopy. Deep red flowering response is most leveraged there.
Why Under-Canopy Lighting Earns Its Place in a Big Plant Flower Room
Top lights starve the lower third of a stretched canopy by week six of flower. That's where lollipopping comes from. Growers typically run the under-canopy LED at 35–40% during early bloom and ramp to 70% during late flower. the fixture dims via Trolmaster or Vivosun controllers and daisy-chains up to 20 fixtures on one schedule. IP66 sealing matters here — these bars catch runoff and condensate that top lights never see.
Key Features
- 80% Red Spectrum: Deep-red diode mix tuned for under-canopy flowering response, pushing photosynthesis on lower bud sites that top lights starve.
- 120W at 2.9 µmol/J PPE: 340 µmol/s PPF in a 46-inch bar form — useful flux for lower-canopy supplementation without adding tent heat.
- IP66 Wet-Location Rated: Sealed for the runoff and condensate exposure that under-canopy fixtures actually face during irrigation cycles.
- Trolmaster + Vivosun Compatible: Dim 35–40% to full intensity via standard 0–10V control gear; no proprietary dimmer required.
- Daisy-Chain Up to 20 Fixtures: Scale across a flower room on one schedule; single power cord runs the whole row.
- 46-in Bar Length: Form factor fits between flower room rows or down the long axis of a 4×4 / 5×5 footprint.
- ETL, DLC, CE, FCC Certified: Full certification stack for commercial install compliance, with a 5-year warranty backing it.
