The Mars Hydro® FC-E4800 480W Commercial LED Grow Light (BridgeLux Edition) is a high-performance, cost-effective multi-bar LED grow light engineered for 4' x 4' grow tents, commercial vertical racking, and medium-scale cultivation setups. Consuming 480 watts of real power, this 4-bar fixture produces a photon flux output of 1,344 µmol/s at a high photon efficacy of 2.8 µmol/J. Designed as an energy-efficient replacement for 800W traditional HPS/MH lighting systems, it delivers uniform light penetration and edge-to-edge PAR coverage across a 5' x 5' vegetative or 4' x 4' flowering footprint.

 

Key Features

• High Efficacy Bar Architecture: Delivers 1,344 µmol/s PPF at 2.8 µmol/J efficacy for deep canopy saturation with low electrical and HVAC demands.

 

• 800W HPS/MH Replacement: Consumes only 480W while providing light intensity comparable to legacy 800W single-ended HID fixtures.

 

• Removable & Adjustable Light Bars: Modular bar layout allows growers to customize fixture dimensions and light spread for unique tent or rack configurations.

 

• Full-Spectrum Light Output: Combines BridgeLux white diodes (2800K–3000K, 4800K–5000K) with 660–665nm deep red LEDs for full seed-to-harvest crop cycles.

 

• Uniform 4x4 Flowering Footprint: Multi-bar design distributes light evenly across 5' × 5' vegetative or 4' × 4' flowering footprints without hot spots.

 

• Fanless Passive Cooling: Thick aluminum heat sinks eliminate mechanical noise (0 dB) while maintaining optimal operating temperatures for extended LED lifespan.

 

• Daisy-Chain & Master Control: Features an onboard rotary dimmer knob (10%–100%) and RJ ports to connect and control up to 30 fixtures simultaneously.

 

Equipped with high-output BridgeLux 2835 white diodes and 660–665nm deep red LEDs mounted on detachable, fully customizable light bars, the FC-E4800 allows growers to alter bar spacing to address unique canopy requirements or perform easy component maintenance. Built with an aluminum heat sink frame for silent passive thermal dissipation, IP65 waterproof clear glue diode shielding, manual step-less dimming (10%–100%), and dual RJ port daisy-chain compatibility, it offers commercial-level utility at an entry-level price point.
