The Mars Hydro FC 4000 OSRAM 320W Smart LED Grow Light is a high-performance, multi-bar LED fixture engineered for 3' x 3' grow tents, multi-tier racks, and personal cultivation spaces. Operating at a true power draw of 320 watts, this bar-style light provides uniform light intensity, deep canopy penetration, and balanced photon coverage across a 4' x 4' vegetative or 3' x 3' flowering footprint.

 

Key Features

• Uniform 4-Bar Array Layout: Multi-bar design ensures edge-to-edge PAR distribution across a 3x3 footprint without creating intense center hot spots.

 

• Smart App Remote Control: Equipped with Bluetooth and Wi-Fi connectivity for wireless scheduling, custom dimming schedules, and sunrise/sunset simulation via the Mars Hydro app.

 

• Osram High-Efficiency Spectrum: Features premium Osram white diodes paired with Osram 660nm deep red LEDs to maximize photosynthesis, canopy penetration, and flowering yields.

 

• 500W–600W HID Equivalent: Consumes only 320W of real power while matching or exceeding the photon flux output of legacy single-ended 500W–600W HID grow lights.

 

• Silent Passive Heat Dissipation: Heavy-duty aluminum heat sink structure eliminates mechanical fans for silent, zero-decibel operation.

 

• IP65 Water & Dust Protection: Protective coating on diode bars guards against micro-climate humidity, mist, and dust inside enclosed grow environments.

 

• 0–100% Onboard & Daisy-Chain Dimming: Features an integrated physical dimmer box and RJ ports to connect and synchronize multiple lights in commercial or multi-tent environments.

 

Equipped with high-efficiency Osram white LEDs paired with Osram 660nm deep red chips mounted across a 4-bar array, the FC 4000 delivers a sunlike full spectrum optimized for all plant growth stages. Upgraded with Mars Hydro Smart App functionality (Bluetooth/Wi-Fi wireless control), growers can easily program light cycles, automate dimming schedules, simulate natural sunrise/sunset effects, and adjust brightness from 0% to 100% remotely. Built with a heavy-duty aluminum passive heat sink, IP65 waterproof diode protection, and daisy-chain connectivity, it delivers commercial-grade reliability and control.
