MARS HYDRO FC-4800 EVO 480W LED Grow Light Full Spectrum — Samsung LM301H EVO, 3x3–4x4 Coverage

The MARS HYDRO FC-4800 EVO is a 480W full-spectrum LED grow light built with Samsung LM301H EVO diodes to deliver high PPE and even canopy coverage for vegetative and flowering stages.

Engineered for small commercial tents and serious hobbyists, the FC-4800 EVO combines a compact folding bar design, robust aluminum heatsink, and a broad full spectrum that supports every growth phase. With a stated PPE up to 2.85 µmol/J and diode-level performance at 3.14 µmol/J, this fixture aims to balance energy efficiency and light intensity while avoiding hotspots thanks to its multi-bar layout. The unit scales from core 3x3 ft coverage up to a 4x4 ft maximum footprint, and it supports optional smart control via the iConnectu Controller for scheduling and dimming over Wi‑Fi or Bluetooth.

How much canopy can this light effectively cover?

The FC-4800 EVO is optimized for compact grow areas. It provides a reliable core cultivation zone of about 3x3 ft for high-intensity runs, while the usable spread can extend to roughly 4x4 ft when plants are more light-tolerant or the light is raised higher.

• Core high-intensity coverage: 3 x 3 ft (recommended for flowering)
• Maximum spread: up to 4 x 4 ft depending on hang height and crop
• Bar-style layout reduces center hotspots, improving uniformity

What spectrum and diodes does it use, and why does that matter?

The fixture uses Samsung LM301H EVO diodes delivering a full-spectrum blend including 650–665nm red and both warm and cool whites (2800–3000K and 4800–5000K). This spectrum mix supports photosynthetic needs across vegetative and reproductive cycles without swapping panels.

• Samsung LM301H EVO for proven luminous efficiency and reliability
• Combined red and white ranges to support leaf development and flowering
• Single fixture covers seedling through harvest with adjustable intensity

How does the FC-4800 manage heat and installation for busy grows?

Heat is controlled through an aluminum heatsink with a slim bar profile that encourages passive dissipation and keeps canopy temperatures stable. The lamp’s folding, 2-in-1 design simplifies mounting and transport for multi-fixture commercial setups.

• Aluminum heatsink design for passive cooling and long component life
• Bar-style panels distribute light evenly to minimize hot spots
• Folding frame reduces installation time and improves portability

Is smart control available, and what features does it add?

Smart control is optional via the iConnectu Controller (sold separately). When paired, growers can manage schedules, sunrise/sunset dimming, and remote operation while still using the onboard manual dimmer for immediate adjustments.

• Wi‑Fi/Bluetooth control through the MarsPro App with iConnectu
• Auto-mode scheduling and gradual sunrise/sunset dimming options
• Mix smart and manual control for flexible multi-fixture setups

Who is this for? The MARS HYDRO FC-4800 EVO is aimed at advanced hobbyists and small commercial growers who need a high-efficiency, full-spectrum fixture that performs across the full plant lifecycle. It fits growers who prioritize energy efficiency (strong PPE figures), uniform canopy coverage without hotspots, and a compact, foldable design for quick deployment. Choose this light if you operate 3x3 to 4x4 ft tents or racks and want the option to upgrade to app-based scheduling and dimming later. If you require integrated controllers out of the box, note the iConnectu Controller is a separate purchase.
