Kill Variance. Print Yield.

Legacy HPS infrastructure does not fail loudly — it fails incrementally. Every hour of lamp operation is an hour of lumen depreciation, spectral drift, and rising radiant heat load that your HVAC system absorbs at full cost. Ballasts cycle inconsistently. Manual dimming zones create dead bands where canopy response diverges from your target DLI. Passive failure points accumulate silently across a fleet: one degraded lamp in a multi-light room introduces enough variance to skew your harvest weight, your cannabinoid panel, and your cycle-over-cycle consistency. The operational cost of that variance is not a line item — it is embedded in every gram you leave on the table.

After deployment of the PhytoMAX-4 16S, the facility operates on a different logic. Canopy density is uniform because every fixture delivers the same spectral output on day one and on day one thousand. Lamp replacement cycles are eliminated from the maintenance calendar. Scheduling runs through industry-standard 0–10V controllers with dim-to-off capability, meaning your photoperiod and intensity ramp are automated and repeatable across every room, every run. HVAC load drops because the fixture's thermal architecture is engineered to minimize radiant heat transfer to the canopy environment. The result is a facility where yield variance is a solvable engineering problem, not an accepted cost of production.

The mechanism behind that outcome is a 448-diode array operating at 1000 watts across the Phyto-Genesis Spectrum® (350–750 nm Beyond PAR™), which includes UV content calibrated at 3% to match natural sunlight — supporting secondary metabolite expression via UV-driven biosynthetic pathways — alongside deep red and near-infrared channels that drive photomorphogenic response at the canopy level. Efficacy is rated at 2.14 µmol/J PBAR (280–800 nm), producing 2125 µmol/s total output. The optical stack uses a glass lens with greater than 99.5% transmissivity, compared to 85–90% for standard plastic or glass optics, ensuring that diode output reaches the canopy rather than being absorbed by the fixture. Active cooling is delivered through oversized heatsinks and a redundant fan array with automatic over-temperature shut-off, and the modular driver platform operates at 94% efficiency. Dimming runs 15–100% (dim-to-off) via 0–10V signal, compatible with industry-standard environmental controllers. In practical terms, the PhytoMAX-4 16S delivers 2125 µmol/s PBAR output at 2.14 µmol/J efficacy from a 19" x 19" x 4.5" fixture drawing 1000 watts and dissipating 3410 BTU/hr.

Where This Belongs (and Doesn't)

Not recommended for circuits under ~8.33A @120V or ~4.17A @240V per fixture, or unsealed rooms lacking HVAC capacity for expected thermal load.

Minimum infrastructure requirement: Dedicated 20A circuit per fixture at 120V, or appropriately rated circuit at 208–277V (SC variant) or up to 250V (SP variant). HVAC capacity must account for 3410 BTU/hr per fixture. Verify electrical and mechanical capacity before fleet deployment.

Infrastructure Note: At 43 lbs per fixture, structural mounting points must be rated for dynamic load with appropriate safety factor. Verify racking, unistrut, or overhead mounting capacity before installation. The SC variant (100–277V, locking water-tight cord) is the preferred configuration for facilities with 208V or 277V three-phase distribution. The SP variant (100–250V, IEC cord) is suited for facilities on standard single-phase distribution up to 250V.

How It Works

The PhytoMAX-4 16S is built around a 448-diode array housed in a 19" x 19" x 4.5" chassis. The diode platform delivers the Phyto-Genesis Spectrum® across the 350–750 nm range (Beyond PAR™), a spectral architecture that extends beyond the conventional 400–700 nm PAR window to include UV wavelengths calibrated at 3% of total output — matching the UV fraction present in natural sunlight — and near-infrared wavelengths that drive photomorphogenic signaling at the canopy level. This full-range spectral delivery is the mechanism behind the lab-tested 39% increase in cannabinoid content and elevated terpene production reported for this platform. The optical path from diode to canopy passes through a glass lens rated at greater than 99.5% transmissivity, a specification that eliminates the 10–15% optical loss typical of standard plastic or glass lenses and ensures that rated output reaches the plant surface rather than being absorbed within the fixture housing.

Thermal management is handled by an oversized heatsink array combined with an active cooling system using redundant fans. Redundancy means a single fan failure does not trigger a thermal shutdown event during a production cycle — the system continues operating while the fault is identified and serviced. Automatic over-temperature shut-off provides a final protection layer. The modular driver design operates at 94% efficiency, minimizing resistive losses and reducing heat generation at the electrical conversion stage. This thermal architecture is the basis for the 40–60% reduction in cooling costs claimed relative to competing light sources, including other LED platforms — a reduction that compounds across a multi-fixture fleet. Dimming is controlled via 0–10V signal across a 15–100% range with dim-to-off capability, compatible with industry-standard environmental controllers. Multiple fixtures can be daisy-chained to a single outlet, reducing electrical infrastructure complexity in large rooms. Black Dog LED's proprietary FloraFlux™ light mapping software models every individual LED for high-resolution canopy uniformity verification during facility design. In practical terms, the PhytoMAX-4 16S delivers 2125 µmol/s PBAR output at 2.14 µmol/J efficacy from a 448-diode array drawing 1000 watts and dissipating 3410 BTU/hr through an active redundant cooling system.

Pick Your Configuration

System Integration

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

• Environmental Controller: 0–10V compatible controller required for automated dimming (15–100%, dim-to-off). Confirm controller output signal matches 0–10V standard before wiring. The PhytoMAX-4 16S is compatible with industry-standard environmental controllers.
• Electrical Infrastructure: SC variant requires circuit rated for 100–277V input; SP variant requires circuit rated for 100–250V input. At 1000W continuous draw, size circuit breakers and wire gauge per NEC 125% continuous load rule. Daisy-chain capability reduces outlet count requirements for multi-fixture rooms — verify daisy-chain load limits with your electrician.
• Mounting: Fixture weight is 43 lbs. Overhead mounting structure (unistrut, racking, or beam) must be rated for dynamic load with appropriate safety factor per local structural code. Mounting height should be set per FloraFlux™ facility design output or Black Dog LED canopy mapping recommendations for target PPFD at canopy.
• HVAC Capacity: Each fixture dissipates 3410 BTU/hr. Size mechanical cooling for total fleet BTU load plus room sensible heat gain. The PhytoMAX-4 16S active cooling system reduces radiant heat transfer to the canopy environment, but total room heat load must be accounted for in HVAC design.

Operator Field Note

• Structural Load: The PhytoMAX-4 16S weighs 43 lbs. Mounting hardware, overhead racking, and attachment points must be rated for this load with a minimum 4:1 safety factor per standard rigging practice. Inspect mounting points before each production cycle.
• Electrical Draw: At 1000W continuous, size branch circuits per NEC 125% continuous load rule — minimum 15.6A at 120V, or proportionally lower at higher voltages. SC variant operates 100–277V; SP variant operates 100–250V. Confirm variant matches facility distribution voltage before installation.
• UV Exposure Warning: The Phyto-Genesis Spectrum® includes UV output (3% of total, 350nm+). Do not view the fixture directly when operating without appropriate UV-protective eyewear. Limit unprotected skin exposure during active operation.
• Thermal Setpoints: Active cooling system includes automatic over-temperature shut-off. Ensure ambient room temperature at fixture level does not exceed manufacturer-specified operating range. Redundant fans extend operational continuity in the event of a single fan failure, but fan condition should be inspected on a scheduled maintenance interval.
• Daisy-Chain Limits: Multiple fixtures can be daisy-chained to a single outlet. Verify total daisy-chain load does not exceed outlet and circuit rating. Consult Black Dog LED or Cannafull Spectrum Solutions for daisy-chain configuration guidance specific to your facility voltage and circuit layout.
