Kill Variance. Print Yield.

Every cycle your facility runs on legacy HPS infrastructure, the variance tax compounds silently. Lamp lumen depreciation begins the moment a bulb fires — by hour 10,000, output has degraded measurably while your electrical draw stays constant. Ballasts drift. Reflectors oxidize. Manual dimming controls introduce dead zones where canopy edges receive inconsistent DLI relative to the center footprint. The result is not a single catastrophic failure — it is a slow, invisible erosion of yield consistency that shows up in harvest weight variance, cannabinoid profile inconsistency, and HVAC systems perpetually chasing a radiant heat load that was never engineered to be controlled.

After deployment, the facility operates on a different logic entirely. Every fixture in the array delivers the same photon output at hour one as it does at hour 50,000. Scheduling is automated through 0–10V dimming integration — no manual intervention, no dead zones, no technician time spent adjusting individual units. Canopy density becomes uniform because the light architecture is uniform. HVAC systems stabilize because the thermal load is predictable and consistent. Lamp replacement cycles disappear from the maintenance calendar. What remains is a production environment where the primary variable is cultivation protocol, not equipment degradation.

The mechanism behind that outcome is a 672-diode array operating at 1500 watts, producing 3187 µmol/s of photon output at a verified efficacy of 2.14 µmol/J. The Phyto-Genesis Spectrum® covers 350–750nm (Beyond PAR™), incorporating 3% UV content calibrated to match natural sunlight's secondary metabolite stimulus — supporting terpene and cannabinoid expression via a spectrally complete diode platform rather than a single-channel approximation. An oversized heatsink structure paired with a redundant active cooling system and redundant power supplies eliminates passive failure points. A glass lens rated at greater than 99.5% transmissivity ensures photon delivery is not attenuated at the fixture exit. Dimming operates from 15–100% (dim-to-off) via 0–10V signal, enabling automated scheduling without external relay hardware. In practical terms, the PhytoMAX-4 24S delivers 3187 µmol/s across a commercial canopy footprint at 1500 watts draw with 5115 BTU/hr thermal output.

Where This Belongs (and Doesn't)

Not recommended for circuits under ~12.5A @120V or ~6.25A @240V per fixture, or unsealed rooms lacking HVAC capacity for expected thermal load.

This fixture draws up to 1500 watts at full output. Verify dedicated circuit capacity, breaker sizing, and HVAC thermal load calculations before installation. Electrical infrastructure must meet local code requirements for commercial damp-location luminaire installation.

Infrastructure Note: At 1500W per unit, a 10-fixture array introduces 15,000W of electrical load and 51,150 BTU/hr of thermal output. HVAC and electrical panel capacity must be engineered to these aggregate figures prior to deployment. Consult a licensed electrical contractor and mechanical engineer for facility-scale integration planning.

How It Works

The PhytoMAX-4 24S is built around a 672-diode array configured to deliver the Phyto-Genesis Spectrum® — a proprietary spectral architecture spanning 350nm to 750nm (Beyond PAR™). This range is not a marketing designation; it is a functional specification. The 3% UV content within the spectrum is calibrated to match the UV fraction present in natural sunlight, providing the photochemical stimulus associated with secondary metabolite production — specifically terpene synthesis and cannabinoid accumulation — that narrower-band LED platforms cannot replicate. The full spectral range from deep UV through near-infrared ensures that photomorphogenic responses across all growth stages are driven by the same fixture without spectral channel switching or supplemental lighting hardware.

Thermal management is handled by an oversized heatsink structure combined with an active cooling system incorporating redundant fans. The redundancy architecture means a single fan failure does not result in fixture shutdown or thermal runaway — the system continues operating while the fault is identified and serviced. An automatic over-temperature shut-off provides a final protection layer. Total heat output is 5115 BTU/hr, a figure that is deterministic and plannable — unlike HPS radiant heat, which varies with lamp age and ballast condition. Power delivery is handled by redundant power supplies, eliminating the single-point failure mode that terminates production cycles in single-supply designs. Driver efficiency is rated at 94%, meaning electrical losses to heat at the driver stage are minimized relative to photon output. The glass lens, rated at greater than 99.5% transmissivity, ensures that photons generated at the diode surface are not attenuated before reaching the canopy. Dimming is executed via 0–10V signal input, covering a 15–100% range with dim-to-off capability, enabling full photoperiod automation through compatible building management or lighting control systems. In practical terms, the PhytoMAX-4 24S delivers 3187 µmol/s of calibrated full-spectrum photon output at 2.14 µmol/J efficacy from a 19" x 19" x 4.5" fixture weighing 47 lbs, drawing 1500 watts across a 100–277V (24SC) or 100–250V (24SP) input range.

Pick Your Configuration

System Integration

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

• Dimming Controller: Requires a 0–10V compatible lighting controller for automated dimming and photoperiod scheduling. Dimming range is 15–100% with dim-to-off capability. Verify controller output signal compatibility before deployment.
• Mounting Infrastructure: Fixture weighs 47 lbs. Mounting structure must be rated for this point load per fixture. Verify racking, truss, or overhead mounting system load ratings before installation.
• Electrical Supply (24SC): Input voltage 100–277V. At 1500W and 120V, draw is approximately 12.5A — dedicate a 20A circuit per fixture minimum. At 240V, draw is approximately 6.25A. Verify breaker and wire gauge to local electrical code.
• Electrical Supply (24SP): Input voltage 100–250V. Same wattage and amperage calculations apply within the 100–250V range. Not rated for 277V distribution.
• HVAC Capacity: Each fixture produces 5115 BTU/hr. Size HVAC systems to aggregate fixture count plus occupancy and infiltration loads. A 10-fixture array requires HVAC capacity for a minimum of 51,150 BTU/hr of fixture-sourced thermal load.

Operator Field Note

• Structural Load: Each PhytoMAX-4 24S weighs 47 lbs. Mounting points, overhead racking, and support structures must be rated for this load per fixture. Do not suspend from unrated wire or chain without verifying load capacity.
• Electrical — Amperage: At 120V, each 1500W fixture draws approximately 12.5A. Minimum 20A dedicated circuit per fixture recommended at 120V. At 240V, draw is approximately 6.25A. At 277V (24SC only), draw is approximately 5.4A. Verify with a licensed electrician to local code.
• UV Content Advisory: The Phyto-Genesis Spectrum® includes UV output (3% UV content, 350nm+). Do not operate with direct, prolonged eye or skin exposure without appropriate UV-protective eyewear and skin protection. Follow all safety protocols for UV-emitting luminaires in occupied spaces.
• Thermal Management: 5115 BTU/hr per fixture is a fixed, deterministic load. HVAC systems must be sized to aggregate fixture count. Do not operate in unventilated or thermally unmanaged spaces — automatic over-temperature shut-off will activate if ambient conditions exceed operating thresholds.
• Redundant Systems: Both fans and power supplies are redundant. If a fan failure indicator or alarm is present in your monitoring system, service the fixture promptly — redundancy provides operational continuity, not indefinite fault tolerance.
• Certifications on File: UL 1598, UL 8800, ETL, CE, FCC, and RoHS certifications should be retained in facility compliance documentation for AHJ inspection and insurance purposes.
