Mars Hydro FC-E4800 480W LED Grow Light offers smart scheduling, 2.8 µmol/J efficiency, and foldable design for maximum yield in 3x3 flower or 4x4 veg grow spaces

Powerful 480W LED grow light with 2.8 μmol/J efficiency, full-spectrum output, and smart app control for 4x4 veg grows.

Smart control meets serious yield power—the Mars Hydro FC-E4800 delivers 1344 µmol/s of full-spectrum intensity with BridgeLux diodes and 2.8 µmol/J PPE. This 480W LED light is built to dominate 3x3 flower zones or 4x4 veg canopies with uniform PPFD and deep canopy reach—without the heat or power draw of HID.

From precise dimming to wireless group control, this grow light was made for growers who want full control and top-tier efficiency. The foldable frame adapts to tight spaces or open racks. Passive cooling cuts heat and noise, and the Mars Hydro APP lets you automate schedules down to the minute with sunrise/sunset simulation. Scale up easily and run clean with a fixture that’s built for multi-cycle performance.

Is the Mars Hydro FC-E4800 Energy-Efficient?

Yes—this unit runs at 2.8 µmol/J PPE, outperforming double-ended HPS (1.8–2.1 µmol/J) and older HID setups (1.3–1.7 µmol/J). That means more grams per watt, less wasted heat, and up to 50% lower energy costs—without compromising yield or spectrum quality.

Features

  • Market-Leading Efficiency boasts a powerful PPF of 1344 µmol/s and 2.8 µmol/J efficacy, making it a cost-effective choice for growers demanding high yields with lower energy costs.
  • Smart Grow Compatibility lets you schedule light intensity, simulate sunrise/sunset, and wirelessly control multiple lights using the Mars Hydro APP—ideal for hands-off, precision grows.
  • Full Spectrum Performance includes red (660-665nm), warm white (2800K-3000K), and cool white (4800K-5000K) wavelengths to maximize photosynthesis across all growth stages.
  • Optimized for 4' x 4' and 3' x 3' Grow Spaces with intense uniform coverage—perfect for tents, closet grows, and vertical rack setups where even canopy penetration is key.
  • Silent Passive Cooling System uses a wave-style aluminum heatsink and spaced bars to quietly manage heat—no fans, no failures, no stress.
  • Foldable, Space-Saving Design adapts to custom and tight spaces while maintaining optimal light distribution across your canopy.
  • Daisy-Chain Control links up to 30 lights, simplifying large-scale operations with a single control system for commercial and home growers alike.
  • Built to Last with Bridgelux diodes, IP65 waterproofing, CE/ETL/RoHS/UKCA certifications, and a 5-year warranty for reliability you can trust in any grow cycle.

FAQs

How many watts do I need for my grow space?

The wattage depends on the size of your grow tent or room. A general guideline is 30-50 watts per square foot for high-light plants like cannabis. For example, a 2x2 ft area may need 100-200W, while a 4x4 ft area may require 400-600W for optimal coverage.

What is the difference between full-spectrum and red/blue LED grow lights?

Full-spectrum LED lights mimic natural sunlight, providing a balanced mix of blue (for vegetative growth) and red (for flowering and fruiting) light. Red/blue LED lights focus on specific wavelengths but may not support plants as effectively as full-spectrum lights.
