Mars Hydro SP 3000 300W LED Grow Light | 2.8 µmol/J PPE

Precision Control in Any Space

Every uncontrolled variable in a compact grow environment compounds into lost output. Fixtures that run hot force operators to raise mounting height, which collapses PPFD at the canopy edge and creates the uneven growth patterns that make harvest weights unpredictable. Single-board designs concentrate heat at the center, leaving perimeter plants starved while core plants risk light stress. Manual dimming with no scheduling architecture means every photoperiod transition is a human error waiting to happen — and every hour of inconsistent intensity is a yield event that never gets logged because it never gets measured. The equipment itself becomes the source of variance, and variance is the silent tax on every gram produced.

After deployment, the operational picture changes materially. A 2x4 ft canopy receives uniform photon density from edge to edge, eliminating the differential growth rates that force operators to rotate plants or accept uneven canopy density at harvest. The bar-style architecture distributes thermal load passively across the fixture length, keeping diode junction temperatures low without active cooling infrastructure. With the optional iConnect Smart USB or iControl Smart Controller, photoperiod scheduling and intensity adjustment move off the manual checklist entirely — operators set parameters once and the fixture executes them consistently across every cycle. No lamp replacement events, no re-lamping labor, no lumen depreciation curves to manage within the rated 50,000-hour service window.

The mechanism behind that outcome is a Bridgelux diode array operating across a full-cycle spectral architecture: 650–665nm red for photosynthetic drive, 2800–3000K warm white for canopy penetration and flowering support, and 4800–5000K cool white for vegetative structure and chlorophyll synthesis. The optical layout is engineered specifically for the 2x4 ft footprint, producing an even PPFD map that eliminates hot spots and weak zones across the entire coverage area. The fixture draws 300W ± 5% at AC100–277V — pulling 2.499A at AC120V, 1.241A at AC240V, or 1.094A at AC277V — and converts that input into 727.2 µmol/s of photosynthetically active photon flux at a photon efficacy of 2.8 µmol/J. IP65-rated diode encapsulation provides protection against water and nutrient splash in high-humidity enclosures, and the ETL, CE, UKCA, RoHS, and IP65 certifications confirm the fixture meets the electrical safety and environmental standards required for licensed facility deployment. In practical terms, the SP-3000B delivers 727.2 µmol/s PPF across a 2x4 ft canopy at 300W draw with passive thermal management and a 50,000-hour rated service life.

Where This Belongs (and Doesn't)

Electrical installation must comply with local codes. Consult a licensed electrician before connecting fixtures to new circuits. HVAC load calculations should account for residual thermal output even in passively cooled configurations.

How It Works

The SP-3000B is built around a Bridgelux diode array configured across three spectral channels that address distinct physiological requirements across the full production cycle. The 650–665nm red channel drives photosynthetic rate at the primary chlorophyll absorption peak, supporting both vegetative biomass accumulation and the photoperiod-sensitive flowering response. The 2800–3000K warm white channel provides canopy-penetrating broad-spectrum output weighted toward the red end, supporting lateral branch development and floral site density during reproductive phases. The 4800–5000K cool white channel delivers blue-weighted broad-spectrum output that regulates internode spacing, leaf morphology, and chlorophyll concentration during vegetative development. Together, these three channels constitute a full-cycle spectral architecture that does not require fixture swaps between growth stages.

The bar-style physical architecture is the thermal management system. By distributing diodes along a linear aluminum bar rather than concentrating them on a single board, the SP-3000B spreads heat generation across a larger surface area, reducing peak junction temperatures and extending diode service life toward the rated 50,000-hour threshold. Passive convection handles heat rejection without fans, eliminating fan noise, fan failure risk, and the maintenance overhead associated with active cooling components. The exclusive waterproof LED casing achieves IP65 certification, protecting diode junctions from water ingress and nutrient solution contact in high-humidity enclosures — a failure mode that terminates board-style fixtures prematurely in wet operating environments.

The optical layout is engineered specifically for the 2x4 ft footprint. Rather than a center-weighted intensity distribution that produces hot spots at the canopy center and PPFD deficits at the perimeter, the SP-3000B's bar geometry produces a uniform PPFD map across the full coverage area. This uniformity is what converts raw PPF output into consistent canopy-level photon density — the difference between a fixture that performs on a spec sheet and one that performs at harvest. The fixture accepts AC100–277V input, drawing 2.499A at AC120V, 1.241A at AC240V, and 1.094A at AC277V, making it compatible with both standard residential-grade and commercial-grade electrical infrastructure. Optional iConnect Smart USB and iControl Smart Controller accessories extend the fixture's control architecture to include scheduling and remote dimming without requiring a proprietary hub. In practical terms, the SP-3000B delivers 727.2 µmol/s PPF at 2.8 µmol/J PPE across a 2x4 ft canopy with passive thermal management, IP65 diode protection, and a 50,000-hour rated service life at 300W draw.

Facility Integration Data

The following fleet-scale projections are based on the SP-3000B's rated 300W draw and 2x4 ft coverage footprint. Electrical cost estimates use a reference rate of $0.12/kWh at 18 hours/day operation; actual costs vary by utility rate and photoperiod schedule.

*Estimate based on $0.12/kWh at 18 hours/day. Actual costs depend on local utility rates, photoperiod schedule, and facility load factors. Consult a licensed electrician for circuit capacity planning at fleet scale.

Operator Field Notes

• Spectral Continuity Across Stages: The three-channel spectral architecture (650–665nm, 2800–3000K, 4800–5000K) eliminates the need to swap fixtures between vegetative and flowering phases — one fixture runs the full production cycle without spectral reconfiguration.
• IP65 in Wet Zones: The waterproof LED casing is not a marketing designation — it is an IP65 ingress protection rating. Operators running foliar applications, overhead irrigation, or high-humidity environments should confirm IP65 coverage before deploying any fixture in those zones.
• Passive Cooling Maintenance Profile: No fans means no fan bearing failures, no fan cleaning intervals, and no fan noise in the grow environment. The passive thermal system requires no scheduled maintenance within the 50,000-hour rated service window.
• Smart Control Is Optional, Not Required: The SP-3000B operates as a standalone fixture without the iConnect or iControl accessories. Smart control integration is additive — it does not affect base fixture performance and can be added to an existing deployment without rewiring.
• Voltage Selection at Installation: The AC100–277V universal input means the fixture does not require manual voltage selection or jumper configuration — it auto-detects input voltage. Verify amperage draw against circuit breaker capacity before connecting: 2.499A at 120V, 1.241A at 240V, 1.094A at 277V.
• Daisy-Chain Planning: When deploying multiple SP-3000B units on a single circuit, calculate cumulative amperage draw before finalizing circuit assignments. At 120V, ten units draw approximately 25A — exceeding a standard 20A breaker. Plan circuit distribution accordingly.
