FACTORY-AUTHORIZED DEALER — CANNAFULL SPECTRUM SOLUTIONS

Deployed in licensed commercial facilities across the United States.

Precision Control in Any Space

Guesswork is the silent budget leak that compounds across every cycle. When your lighting infrastructure operates without reliable dimming resolution, without schedulable control, and without consistent photon delivery across the canopy, the variance doesn't announce itself — it shows up in uneven density, extended finishing windows, and yield numbers that never quite match the room's potential. Equipment that fights you at the control level costs more than its sticker price suggests: every manual adjustment that doesn't hold, every lamp that drifts below rated output before replacement, every dark corner in a canopy that should be uniform — these are operational losses that accumulate invisibly until they define your facility's ceiling.

After deployment, the room changes character. A 4×2 ft cultivation footprint receives consistent, calibrated photon flux from a fixture that requires no active cooling infrastructure, generates no fan noise, and holds its output across a rated 50,000-hour lifespan. Scheduling and dimming are no longer manual operations — with the Mars Hydro iConnect Smart Controller, lighting programs run on defined parameters, not operator availability. The canopy receives what it needs, when it needs it, at every growth stage from seedling through flower, without the intervention overhead that manual systems demand.

The mechanism behind that outcome is a 765-diode array built entirely on Samsung LM301H EVO chips, the current benchmark for per-diode efficacy in horticultural applications at 3.14 µmol/j per diode. At the system level, the FC 4000 EVO delivers 2.85 µmol/j across a 320W ±5% draw at AC120-277V — a wide voltage range that accommodates both standard and high-voltage facility circuits without hardware modification. The full-spectrum output spans 650-665nm, 2800-3000K, and 4800-5000K channels, covering the red and blue wavelength bands critical to photosynthetic efficiency across all growth stages. Passive thermal management via the bar-style aluminum chassis eliminates moving parts entirely, removing the primary mechanical failure point present in fan-cooled fixtures. The foldable design and daisy-chain capability allow scalable deployment across multi-fixture configurations without proportional increases in control complexity. In practical terms, the FC 4000 EVO delivers 912 µmol/s PPF across a 3'x5' maximum coverage footprint (4×2 ft cultivation coverage) at 320W with a 2.85 µmol/j system efficacy and zero active cooling components.

Where This Belongs (and Doesn't)

Electrical note: The FC 4000 EVO operates at AC120-277V. At AC120V, draw is 2.715A; at AC240V, 1.343A; at AC277V, 1.169A. Verify circuit capacity and breaker ratings before installation. HVAC load planning should account for 1,023 BTU/hr per fixture. Consult a licensed electrician for multi-fixture daisy-chain configurations.

How It Works

The FC 4000 EVO's output architecture begins at the diode level. Each of the 765 Samsung LM301H EVO chips operates at a per-diode efficacy of 3.14 µmol/j — the current ceiling for commercially available horticultural diodes. The chip arrangement is scientifically optimized for even light distribution across the coverage footprint, eliminating the hot-spot patterns that characterize single-point or poorly arrayed fixtures. The full-spectrum configuration covers three distinct channels: 650-665nm (targeted red for photosynthetic absorption), 2800-3000K (warm white for broad-spectrum fill), and 4800-5000K (cool white for vegetative and blue-band support). All three channels operate simultaneously, delivering a complete photon profile across seedling, vegetative, and flowering stages without fixture swaps or spectrum adjustments.

Thermal management is entirely passive. The bar-style aluminum chassis conducts and dissipates heat across its 44×14×2.5 inch profile without fans, motors, or any moving components. This eliminates the primary mechanical failure mode in LED fixtures — fan bearing degradation — and contributes directly to the 50,000-hour rated lifespan. The absence of active cooling also means zero fan noise and no airflow interference with canopy microclimate management. At 1,023 BTU/hr, the fixture's thermal output is predictable and consistent, simplifying HVAC load calculations for multi-unit rooms.

Dimming is built in and operates across the full output range, allowing operators to calibrate intensity to growth stage requirements without hardware changes. The foldable design enables compact shipping and simplified installation positioning. Daisy-chain capability allows multiple FC 4000 EVO units to be linked and controlled as a unified array — a critical feature for operators expanding canopy coverage incrementally. Smart scheduling and automated control require the separately purchased Mars Hydro iConnect Smart Controller, which integrates with the fixture's control architecture via the iConnect protocol. In practical terms, the FC 4000 EVO delivers 912 µmol/s PPF at 2.85 µmol/j system efficacy across a 4×2 ft cultivation footprint at 320W ±5%, with a 50,000-hour passive-cooled lifespan and full-range dimming across all three spectral channels.

Operator Field Notes

Dimming without a controller: The FC 4000 EVO supports manual dimming natively. Automated scheduling and remote control require the separately purchased Mars Hydro iConnect Smart Controller — budget this into your deployment plan before installation.
Cultivation vs. maximum coverage: The 3'x5' maximum coverage figure represents the outer photon boundary. The 4×2 ft cultivation coverage is the recommended footprint for production-grade PPFD uniformity. Size your room layout to cultivation coverage, not maximum coverage.
Passive cooling and airspace: The bar-style chassis requires adequate overhead airspace for convective heat dissipation. Do not mount flush against reflective ceilings or enclosed canopies without verifying thermal clearance.
Daisy-chain circuit loading: When linking multiple units, calculate cumulative amperage against circuit capacity before energizing. At AC120V, each unit draws 2.715A — a 10-unit daisy chain requires a dedicated 30A circuit minimum.
Lifespan planning: The 50,000-hour rated lifespan at standard operating conditions means no lamp replacement cycles within a typical 5-7 year facility depreciation window, assuming 18-hour daily operation schedules.
Yield benchmark: The published 3.5g/W max yield figure represents an optimized-condition ceiling, not a guaranteed per-cycle output. Actual yield is a function of genetics, nutrition, environment, and canopy management in addition to photon delivery.

Operator FAQ

Q: What is the difference between the 3'x5' maximum coverage and the 4×2 ft cultivation coverage?

A: Maximum coverage (3'x5') represents the outer boundary of measurable photon delivery from the fixture — the area where light reaches but may not achieve production-grade uniformity or intensity. Cultivation coverage (4×2 ft) is the manufacturer-specified footprint where PPFD uniformity and intensity are optimized for active production across all growth stages. For yield-critical applications, room layout and fixture spacing should be based on the 4×2 ft cultivation coverage figure.

Q: Does the FC 4000 EVO require an active cooling system or dedicated exhaust?

A: No. The FC 4000 EVO uses passive thermal management through its bar-style aluminum chassis — there are no fans, motors, or active cooling components. The fixture dissipates 1,023 BTU/hr through convection. Adequate overhead airspace and room-level HVAC capacity are required, but no dedicated exhaust or active cooling is needed at the fixture level.

Q: Is smart scheduling included, or does it require additional hardware?

A: Smart scheduling and automated control require the separately purchased Mars Hydro iConnect Smart Controller. The FC 4000 EVO supports manual dimming natively without the controller. For automated photoperiod scheduling, remote dimming, and multi-fixture coordination, the iConnect controller must be purchased and integrated separately. Budget this hardware into your deployment plan before installation.

Q: What voltage configurations does the FC 4000 EVO support, and how does that affect amperage draw?

A: The FC 4000 EVO operates across AC120-277V without hardware modification. Amperage draw varies by voltage: 2.715A at AC120V, 1.343A at AC240V, and 1.169A at AC277V. Higher-voltage circuits reduce per-fixture amperage draw, which is relevant for multi-fixture daisy-chain configurations and circuit capacity planning. Consult a licensed electrician to verify circuit ratings before installation.

Q: What certifications does the FC 4000 EVO carry, and are they relevant to U.S. commercial facility compliance?

A: The FC 4000 EVO carries ETL, CE, UKCA, and RoHS certifications. ETL listing is the primary U.S. commercial facility compliance certification — it indicates the fixture has been tested to North American safety standards by an OSHA-recognized Nationally Recognized Testing Laboratory (NRTL). CE and UKCA are European and UK market certifications. RoHS confirms restriction of hazardous substances in the fixture's construction. For U.S. facility insurance, inspection, and permitting purposes, the ETL listing is the operative certification.

Q: How does the FC 4000 EVO's per-diode efficacy of 3.14 µmol/j relate to the system efficacy of 2.85 µmol/j?

A: Per-diode efficacy (3.14 µmol/j) measures the photon output efficiency of each Samsung LM301H EVO chip in isolation. System efficacy (2.85 µmol/j) measures the total photon output of the complete fixture — including driver losses, thermal derating, and electrical conversion overhead — divided by total power input. The gap between the two figures represents the efficiency cost of the driver and power conversion components. A system efficacy of 2.85 µmol/j is a strong commercial-grade figure and reflects a well-optimized driver design relative to the diode array's rated output.
