Mars Hydro TSW2000 300W LED Grow Light | 2.6 μmol/J PPE

Precision Control in Any Space.

Every uncontrolled variable in a compact production environment compounds into lost output. Fixtures that run at fixed intensity force operators into a binary choice — full power or off — leaving seedling and vegetative stages chronically over-driven or under-served. Heat from active cooling systems raises ambient temperature, narrows your environmental control window, and introduces mechanical failure points that don't announce themselves until a crop cycle is already compromised. Lamp depreciation in legacy HID systems is silent and continuous: output degrades from the first hour of operation, and the replacement schedule it demands is a recurring cost that never appears on the original equipment quote. The result is a production environment where the lighting system is working against the operator rather than for them.

After deployment, the operational picture changes materially. Intensity is dialed to the exact PPFD target for each growth stage — 25% at seeding, 75% through vegetative development, 100% at peak flowering — without touching the fixture. Multiple units across a facility run synchronized dimming and switching through a single daisy-chain connection, eliminating the manual adjustment labor that accumulates across a multi-light installation. No fans means no moving parts to service, no audible noise signature, and no additional heat load injected into the canopy environment. The fixture runs, the canopy responds, and the operator's attention stays on cultivation decisions rather than equipment management.

The mechanism behind that outcome is a BridgeLux diode array operating at 300W ± 5% across AC100–277V input, producing 776 µmol/s total photon flux at a verified 2.6 µmol/J photon efficacy. The spectral architecture spans 660–665nm red, 730–740nm far-red, 3000–3200K warm white, and 6000–6500K cool white channels, with IR content integrated for canopy penetration and secondary metabolite support. Stage-specific PPFD ranges are operationally defined: 150–350 µmol/m²/s for seeding and clone, 550–1,000 µmol/m²/s for vegetative, and 700–1,300 µmol/m²/s for flowering. The white reflector housing maximizes photon redirection toward the canopy plane, and the 0–100% dimming range is accessible via the included dimmer wire or, with a separately purchased iConnect unit, through the MarsPro Bluetooth app. In practical terms, the TSW2000 delivers 776 µmol/s PPF across a 4x4 maximum coverage footprint at 300W draw and 1,023 BTU thermal output, with a fanless passive cooling profile that adds zero mechanical heat load to the grow environment.

Where This Belongs (and Doesn't)

Electrical installation must comply with all applicable local codes. Consult a licensed electrician before modifying circuits or load configurations. HVAC load calculations should account for the 1,023 BTU thermal output of each unit deployed.

How It Works

The TSW2000 is built on a BridgeLux diode array configured in a flat-panel form factor measuring 22 x 20 x 2.7 inches. The diode selection covers four spectral channels: 660–665nm deep red for photosynthetic peak absorption, 730–740nm far-red for canopy penetration and photoperiod signaling, 3000–3200K warm white for broad-spectrum vegetative and flowering support, and 6000–6500K cool white for blue-channel vegetative development. IR content is integrated into the spectral output to support secondary metabolite expression and canopy depth penetration. The white reflector housing redirects photons that would otherwise be lost to fixture surfaces back toward the canopy plane, contributing to the fixture's 2.6 µmol/J photon efficacy rating.

Thermal management is entirely passive. There are no fans, no moving parts, and no mechanical components subject to wear or failure. The 1,023 BTU thermal load is dissipated through the fixture body without active intervention, which eliminates fan noise, removes a maintenance variable, and prevents the fixture itself from injecting additional forced-air heat into the canopy zone. Input voltage acceptance spans AC100–277V, drawing 2.451A at AC120V, 1.227A at AC240V, and 1.082A at AC277V, making the fixture compatible with standard U.S. facility electrical infrastructure without step-down transformers or dedicated circuits beyond standard load calculations.

Intensity control operates across a 0–100% continuous dimming range via the included dimmer wire. Daisy-chain connectivity allows multiple TSW2000 units to be linked for simultaneous switching and dimming from a single control point — a critical capability for operators running multi-light installations who need uniform intensity adjustments across an entire zone without individual fixture access. Full Bluetooth control through the MarsPro app requires the separately purchased iConnect unit; the iTime Dual-Plug Timer is compatible for scheduling but does not support dimming through that interface. The fixture is rated for 50,000 hours of operational life and carries ETL, CE, RoHS, and UKCA certifications. In practical terms, the TSW2000 delivers 776 µmol/s PPF at 2.6 µmol/J across a 4x4 vegetative footprint and a 3x3 flowering footprint, drawing 300W ± 5% at 1,023 BTU thermal output with zero active cooling components.

System Integration

• Daisy Chain: Multiple TSW2000 units connect via included dimmer wire for synchronized switching and dimming across a multi-light zone from a single control point.
• App Control: MarsPro Bluetooth app integration is available with the separately purchased iConnect unit, enabling remote intensity scheduling and adjustment.
• Timer Scheduling: Compatible with the Mars Hydro iTime Dual-Plug Timer for photoperiod scheduling; note that dimming is not supported through this timer interface.
• Electrical Compatibility: AC100–277V input accepts standard U.S. facility voltages at 120V, 240V, and 277V without additional conversion hardware.
• Thermal Integration: Passive cooling profile produces 1,023 BTU per unit; include this figure in facility HVAC load calculations for each deployed fixture.

Operator Field Notes

• Stage-Specific Dimming: Operational guidance positions dimmer settings at approximately 25% for seeding and clone, 75% for vegetative development, and 100% for peak flowering — dial to your measured PPFD targets, not to a fixed percentage.
• Hanging Height: Manufacturer-recommended hanging height range is 12–18 inches above canopy; adjust within that range based on stage-specific PPFD targets and canopy response.
• iConnect Requirement: Full MarsPro Bluetooth app functionality — including remote scheduling and app-based dimming — requires the iConnect unit, which is sold separately and is not included with the TSW2000.
• Timer Dimming Limitation: The iTime Dual-Plug Timer supports photoperiod scheduling but does not pass dimming commands; use the dimmer wire or iConnect for intensity control.
• Daisy Chain Wiring: The dimmer wire included with the product enables daisy-chain connection for simultaneous switching and dimming across multiple units — confirm total daisy-chain load against your circuit capacity before deployment.
• Thermal Planning: At 1,023 BTU per unit, a 10-unit installation contributes 10,230 BTU of thermal load to the grow environment; size HVAC accordingly before commissioning.
