Kill Variance. Print Yield.

Every uncontrolled variable in a legacy lighting system is a silent tax on your facility's output. HPS lamps begin depreciating from the moment they strike — spectral shift, lumen decay, and thermal inconsistency compound across every harvest cycle. Passive failure points accumulate invisibly: a lamp running at 70% output looks identical to one running at 100% until your canopy data tells a different story. Manual control dead zones mean your team is reacting to variance instead of executing a repeatable production protocol. The longer legacy infrastructure stays in place, the wider the gap between your facility's actual yield and its engineered potential.

After deployment of the PhytoMAX-4 12S, the operational picture changes structurally. Canopy density becomes uniform because every fixture delivers the same spectral output on day one and on day 27,000. Scheduling is automated through 0-10V dimming architecture, eliminating manual intervention from the photoperiod workflow. Lamp replacement cycles disappear from the maintenance calendar entirely. Your cultivation team stops managing equipment degradation and starts executing yield protocols — and the facility's output becomes a function of agronomic decisions, not infrastructure entropy.

The mechanism behind that outcome is the Phyto-Genesis Spectrum® — a full-range spectral platform spanning 350–750 nm (Beyond PAR™) that includes UV content at 3% of total output to match natural sunlight conditions, driving secondary metabolite expression and documented cannabinoid increases of 39% in lab testing. The PhytoMAX-4 12S delivers 1,594 µmol/s total PBAR output (UV: 47, PAR: 1,428, IR: 119 µmol/s) from 336 LEDs at 2.14 µmol/J PBAR efficacy, housed in a 15" x 15" x 4.5" fixture weighing 28 lbs. Active cooling via oversized heatsinks and redundant fans maintains thermal stability across the full operating range of -4 to 104°F, while modular drivers at 94% efficiency and automatic over-temperature shut-off eliminate passive failure points at the electrical level. Dimming runs 15–100% via 0-10V signal (dim-to-off capable) and is compatible with industry-standard controllers. In practical terms, the PhytoMAX-4 12S delivers 1,594 µmol/s PBAR across its coverage footprint at 750 watts draw and 2,558 BTU/hr thermal load.

Where This Belongs (and Doesn't)

Not recommended for circuits under ~6.25A @120V or ~3.13A @240V per fixture, or unsealed rooms lacking HVAC capacity for expected thermal load.

Minimum infrastructure requirement: Dedicated 20A circuit per fixture at 120V, or verify amperage draw at operating voltage before installation. HVAC capacity must account for 2,558 BTU/hr per fixture; consult your mechanical engineer before scaling fleet deployments.

Infrastructure Note: The 12SC variant accepts 100–277V input with a locking, water-tight power cord — appropriate for sealed commercial rooms with varied electrical infrastructure. The 12SP variant accepts 100–250V with an IEC power cord and is restricted to indoor sealed environments only. Confirm variant selection against your facility's electrical specification before ordering.

How It Works

The PhytoMAX-4 12S operates on the Phyto-Genesis Spectrum® — a proprietary full-range spectral architecture spanning 350–750 nm (Beyond PAR™) that goes beyond conventional PAR-only LED platforms. The spectrum is engineered to replicate natural sunlight conditions at the canopy level, including UV content at 3% of total output (47 µmol/s UV), which drives secondary metabolite expression — documented in lab testing as a 39% increase in cannabinoid content and elevated terpene production relative to PAR-only lighting environments. The IR channel (119 µmol/s) extends the photobiologically active range beyond 700 nm, supporting end-of-day far-red signaling and canopy penetration into lower tier foliage. Total PBAR output is 1,594 µmol/s from 336 LEDs, delivered through a glass lens with greater than 99.5% transmissivity to minimize photon loss between source and canopy.

Thermal management is handled by an active cooling system combining oversized heatsinks with redundant fans and redundant power supplies — eliminating the single-point failure modes that cause unplanned downtime in passive-cooled platforms. Modular drivers operate at 94% efficiency, and automatic over-temperature shut-off provides a hardware-level safety backstop independent of controller input. The fixture accepts 100–277V (12SC) or 100–250V (12SP) input, draws 750 watts, and produces 2,558 BTU/hr of thermal load — a 40–60% reduction in cooling cost compared to equivalent HPS infrastructure. Dimming is controlled via 0-10V signal across a 15–100% range (dim-to-off capable), compatible with industry-standard environmental controllers, and supports daisy-chaining of multiple fixtures to a single outlet for simplified zone control. FloraFlux™ proprietary light mapping software models output from every individual LED, enabling facility-level PPFD mapping before physical deployment. The fixture measures 15" x 15" x 4.5" and weighs 28 lbs, with flush-ceiling mounting capability for maximum canopy clearance in low-profile rooms. In practical terms, the PhytoMAX-4 12S delivers 1,594 µmol/s PBAR at 2.14 µmol/J efficacy across a 5 x 5 ft flower footprint at 750 watts and 2,558 BTU/hr thermal output.

Pick Your Configuration

System Integration

To operate this platform at peak efficiency, verify your ecosystem matches these requirements:

• Controller Compatibility: Requires 0-10V signal controller for dimming (15–100% range, dim-to-off capable). Compatible with industry-standard environmental controllers. Daisy-chain capability allows multiple fixtures per controller output zone.
• Mounting: Flush-ceiling mount capable. Verify structural load rating for 28 lbs per fixture at your mounting point. Ratchet hangers or manufacturer-specified mounting hardware required for suspended configurations.
• Electrical: 12SC: 100–277V input, locking water-tight cord. 12SP: 100–250V input, IEC cord. Confirm circuit amperage capacity at your operating voltage before installation. Daisy-chain wiring must remain within circuit capacity limits.
• HVAC Capacity: Each fixture produces 2,558 BTU/hr. Size mechanical cooling to total fleet BTU load. Black Dog LED claims 40–60% reduction in cooling cost versus equivalent HPS infrastructure — validate against your facility's existing HVAC baseline before projecting savings.
• Operating Environment: Rated for -4 to 104°F / -20 to 40°C. Sealed room environments with active climate control are the intended deployment context. 12SP variant is not approved for greenhouse use.

Facility Integration Data

The following ROI model and comparison table are provided as planning tools for facility directors evaluating fleet-scale deployment of the PhytoMAX-4 12S against legacy 1000W DE HPS infrastructure.

Operator Field Note

• Structural Load: Each fixture weighs 28 lbs. Verify ceiling or racking structural capacity before mounting, particularly in multi-fixture grid configurations. Flush-mount ceiling installation is supported by the manufacturer.
• Electrical Draw: 750W at operating wattage. At 120V, expect approximately 6.25A per fixture; at 240V, approximately 3.13A. Confirm actual amperage at your supply voltage and size circuits accordingly. Do not exceed 80% of circuit breaker rating per NEC guidelines.
• UV Exposure Warning: The Phyto-Genesis Spectrum® includes UV output (47 µmol/s, 3% of total PBAR). Do not view the fixture directly when operating. Use appropriate UV-protective eyewear during canopy inspection under active fixtures.
• Thermal Setpoints: Operating range is -4 to 104°F / -20 to 40°C. Automatic over-temperature shut-off is a hardware-level protection — do not rely on it as a substitute for properly sized HVAC. Sustained ambient temperatures approaching 104°F will trigger shut-off and interrupt photoperiod schedules.
• Redundancy Architecture: Redundant fans and redundant power supplies are integrated into the fixture. A single fan or power supply failure will not cause immediate fixture shutdown, but maintenance should be scheduled promptly upon any component fault indication.
• Daisy-Chain Limits: Multiple fixtures can be daisy-chained to a single outlet. Total daisy-chain load must remain within the circuit's rated capacity. Calculate total wattage across all chained fixtures before wiring.
