The Mars Hydro® FC 4000 Smart 320W LED Grow Light (Bridgelux Diode Edition) is an ultra-efficient, commercial-grade 4-bar LED fixture engineered for medium-sized grow tents, vertical rack shelving, and targeted commercial setups. Drawing 320 watts of power, this high-performance system delivers a photon flux output of 912 µmol/s at an efficacy of 2.85 µmol/J. Designed as an energy-saving replacement for traditional 600W single-ended HPS/MH lighting systems, it dramatically lowers electrical draw and HVAC cooling demands while providing uniform canopy penetration across a 4' x 4' vegetative or 3' x 3' flowering footprint.

 

Key Features

• High Efficacy Bar Output: Generates 912 µmol/s PPF at 2.85 µmol/J efficacy to maximize canopy light saturation per watt consumed.

 

• 600W HPS/MH Alternative: Consumes only 320W while matching the light intensity of legacy 600W single-ended HID systems.

 

• Smart Mobile App Automation: Integrated Wi-Fi and Bluetooth allow remote dimming, custom light scheduling, and multi-unit group control via the Mars Hydro app.

 

• Cost-Effective Bridgelux Diodes: Formulated with high-grade Bridgelux 3030 white LEDs and Osram-grade 660nm deep red diodes for full-cycle plant response.

 

• Uniform 3x3 Flowering Coverage: 4-bar layout distributes light evenly across 4' × 4' vegetative or 3' × 3' flowering grow areas without local hot spots.

 

• Silent Passive Thermal Control: Heavy-duty aluminum heat sink dissipates heat efficiently without noisy mechanical fans (0 dB operation).

 

• IP65 Waterproof Protection: Clear glue protective coating shields diode chips against water spray, dust, and humid grow tent environments.

 

Equipped with premium Bridgelux 3030 white LEDs and 660–665nm deep red diodes, the FC 4000 Smart emits a sunlike full spectrum tailored for all growth stages from vegetative development through heavy bloom. Built with a thick aluminum heat sink frame for silent passive cooling, IP65 waterproof clear glue diode shielding, integrated smart app control via Wi-Fi and Bluetooth, manual step-less dimming (10%–100%), and daisy-chain ports, it provides precise light management and effortless facility automation.
