Faven Under Canopy Light Chroma 3.0

What the Chroma 3.0 Is

The Faven Chroma 3.0 is a commercial-grade under canopy LED bar designed to deliver photosynthetically active radiation directly to lower bud sites that overhead fixtures cannot reach effectively. The bar runs 120W of primary spectrum output plus a fully independent 15W far-red channel — two separate drivers in one 46-inch form factor.

Spectrum control spans six preset recipes labeled R4 through R9, shifting red content from 40% (R4, full-spectrum balanced) to 90% (R9, high-red finish). Each recipe is a fixed ratio of red to white, not a single-wavelength tuner, which keeps the steering strategy straightforward for cultivation teams working at scale without requiring individual diode-level programming.

The far-red channel operates entirely on its own control path — it can run before lights-on, after lights-off, or alongside any of the six spectrum recipes without affecting the primary driver settings. The fixture maintains Faven's 5-year warranty and IP66 waterproof rating across all operating configurations.

Who It's For

The Chroma 3.0 is built for licensed cannabis and hemp cultivation facilities that are already running a primary top-light system and want to add addressable under canopy coverage without retrofitting their ceiling infrastructure. It is equally applicable to multi-tier vertical grows, single-canopy benched rooms, and rolling-bench light dep setups where overhead DLI at the lower third of the plant is consistently low.

Operators focused on flower quality — terpene profile, bud density, anthocyanin expression, or finishing consistency — will get the most utility from the spectrum recipe system. Growers chasing faster cycle times benefit specifically from the independent far-red channel: end-of-day far-red treatments are a documented method for compressing photoperiod response and reducing days-to-harvest. Facilities producing hash or solventless extract where raw biomass density at lower bud sites directly affects yield per plant are also well-suited for this fixture.

The Chroma 3.0 scales from single-bench CX2 deployments up to large multi-zone commercial rooms managed through GrowFlux — the same fixture, different controllers. Operations that already use 0–10V or approved RS485 infrastructure can integrate Chroma without replacing existing control hardware.

Key Technical Features

Spectrum tunability runs from R4 (40% red, suitable for early vegetative and stretch management) through R9 (90% red, used for finishing, ripening, and anthocyanin production). The mid-range recipes — R6 and R7 — provide a balanced profile appropriate for canopy development and bud-site sizing during bulk. The six-step system is designed to be repeatable across cultivation teams without specialized horticulture lighting knowledge.

The independent far-red channel provides 15W at wavelengths around 700–750 nm and is configured to run on its own schedule, separate from the primary spectrum driver. This allows end-of-day far-red treatments, Emerson Effect stacking with the primary deep red output, and flowering transition protocols without disrupting the main lighting recipe for the room.

The Chroma 3.0 achieves up to 2.9 µmol/J efficacy and is certified ETL, DLC, CE, and FCC. DLC certification means the fixture qualifies for utility energy-efficiency rebates in most US markets — rebate amounts vary by utility and program. The fixture daisy-chains at up to 17 units per circuit at 240V and 20 units per circuit at 277V, keeping electrical infrastructure requirements manageable on large bench runs. Power cords, controllers, and mounting accessories are sold separately.

How It Fits a Commercial Build

Under canopy lighting is most effective when positioned at substrate level on adjustable stands, directing PAR upward to the lower bud sites. The Chroma 3.0 mounts on Faven's adjustable stands (sold separately, adjustable to 8", 10", or 12" height) and fixtures connect together without interconnecting cables in a straight run. Interconnecting cables are required only when creating a U-shaped configuration across two rows on a single bench.

For large commercial facilities with multiple lighting zones and complex recipe management, GrowFlux provides wireless, app-based control with spectrum tuning, scheduling, and remote access — supporting up to 99 lights per dimmer and 99 dimmers per access point at approximately 500-foot range. For smaller builds or single-room operations, the CX2 controller handles manual dimming, spectrum recipe selection, and far-red scheduling for up to 100–150 fixtures per unit.

Note: A controller is required to operate the Chroma 3.0. The fixture uses a dual-driver RS485 protocol rather than standard analog 0–10V, so a compatible controller or approved RS485 adapter is necessary for operation. Chroma fixtures are not cross-compatible with Faven's R6/R8 series on the same controller.
