120W, 2.9 µmol/J, 80% red — purpose-built supplemental lighting for LED and greenhouse flower rooms.
The Faven R8 is a 120W dimmable LED under canopy bar delivering 340 µmol/s PPF at 2.9 µmol/J efficacy, tuned to an 80% red spectrum for inter-canopy flowering response in LED-top-light and greenhouse environments. IP66-rated, ETL/DLC/FCC/CE certified, and daisy-chainable up to 20 fixtures per circuit — built for commercial-scale deployment.
Overhead fixtures are engineered to drive canopy tops. Past roughly 18 inches into a dense flower canopy, photon delivery drops sharply — leaving lower bud sites operating at a chronic light deficit. The result is familiar: slow-trimming popcorn, inconsistent color, and labor-intensive lollipopping to manage what light deprivation creates.
The Faven R8 is a 46-inch LED bar placed directly inside the plant canopy — between rows, mid-plant — to deliver 120W of 80% red-spectrum light precisely where overhead fixtures can't reach. At 2.9 µmol/J and 340 µmol/s PPF, it puts meaningful photon flux on lower bud sites without materially increasing the facility's heat load. The internal driver is dimmable via 0–10V control, so intensity can be dialed from approximately 35–40% up to full power depending on growth stage and genetics.
Faven builds two separate R-Series spectrums — one for HID/HPS rooms (R6) and one for LED and greenhouse environments (R8). The distinction matters: full-spectrum LED top lights are already delivering blue, green, and white wavelengths throughout the canopy. What the lower canopy lacks is red-spectrum depth, not broadband output.
The R8's 80% red spectrum is calibrated to complement the existing spectral profile of LED top lights, not replicate it. The deeper red ratio drives flowering response on lower bud sites, accelerates maturity uniformity from top to bottom, and supports color development across the canopy. For mixed-light and greenhouse operators whose top-light spectrum skews toward full-white or CMH, the same logic applies — the R8 fills the red gap the overhead fixture doesn't fully cover.
Dimming discipline also changes by stage: early flower typically runs 35–40% to acclimate plants to the added light plane; late flower often steps back to 70–80% for genetics that stress under sustained high intensity in the final two weeks.
The R8 is designed for room-scale deployment, not rack-by-rack one-offs. Fixtures daisy-chain up to 10 units at 120V, 17 at 240V, or 20 at 277V per circuit — so a multi-bench flower room can run on a manageable number of power cords, each driving a full row of bars on one schedule. Jumper cables (3 ft and 9 ft, sold separately) allow spacing between fixtures where bench geometry requires it rather than butting bars end-to-end.
Dimming is handled via a 0–10V RJ-port input (Faven Mini Controller, TrolMaster, or Vivosun compatible) connecting into the first light in the chain and propagating intensity across all linked fixtures simultaneously — 9 discrete levels plus full power. A separate timer controls on/off scheduling; the controller manages intensity only.
The R8 carries an IP66 wet-location rating, making it safe through irrigation cycles, condensate drip, and the general humidity load of a commercial flower room. Certifications include ETL, DLC, CE, and FCC — qualifying the fixture for utility and electrical rebate programs in most states, which meaningfully improves the payback timeline on large installs. Faven backs the fixture with a 5-year manufacturer warranty.
The R8 installs on Faven Adjustable Stands (sold separately) in three height positions — 8", 10", or 12" — positioning the bar relative to mid-canopy. Mounting height relative to the lower bud zone directly affects PPFD uniformity across the lower third of the plant; the ability to reposition from veg through late flower gives cultivation directors a real-time tool for light management that overhead fixtures can't offer.
For layout planning: convert your bench length to inches and divide by 46 to determine fixtures per row. Each bench requires at least one dedicated power cord; additional rows can be linked with jumper cables up to the voltage-rated daisy-chain maximum. Commercial facilities with multiple benches should request a lighting layout through HSC — we can map fixture count, circuit loading, and cord routing across your specific floor plan before you place the order.
Cords, stands, controllers, and jumper cables are all sold separately and available through HSC alongside the R8 bars.

The R8 (80% red) is designed for LED top-light rooms, mixed-light rooms, and greenhouses. The R6 is tuned for HID/HPS rooms. Faven built separate spectrums because HID and LED top lights have very different spectral profiles; the under canopy fixture needs to complement what the overhead is already delivering, not duplicate it. If your canopy is lit from above by full-spectrum LED or CMH fixtures, specify the R8.
Convert your bench length to inches, then divide by 46 — that gives you fixtures per row. Each bench needs at least one power cord; additional rows can be linked with jumper cables up to the voltage-rated maximum (10 fixtures at 120V, 17 at 240V, 20 at 277V). For commercial facilities with multiple benches, contact HSC for a full lighting layout — we'll map fixture count, cord routing, and circuit loading across your floor plan.
Yes. The R8 carries DLC (DesignLights Consortium) listing, which is the primary qualification standard most utility rebate programs require for horticultural lighting. ETL and FCC certifications also support commercial electrical permitting. Rebate availability and amounts vary by utility and state — HSC can help you identify applicable programs when you request a quote.
The R8 dims via a 0–10V signal input at the RJ port on the first fixture in a daisy chain, with that signal propagating to all linked bars simultaneously across 9 intensity levels (plus full power). It is compatible with the Faven Mini Controller, TrolMaster, and Vivosun 0–10V controllers — no proprietary hardware required. The controller manages intensity only; a separate timer is required to control on/off scheduling. Dimming range is approximately 35–40% to 100%.
Yes. The R8 carries an IP66 wet-location rating, which means it is fully sealed against dust ingress and protected against strong water jets — the standard that matters in an actively irrigated commercial grow room. Waterproof connectors at each junction point handle condensate and irrigation splash without issue. That said, avoid directing irrigation spray directly at electrical connection points, and ensure all junctions are fully seated before operation.
