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.\u003c\/p\u003e\n\n\u003ch3\u003eHow much canopy can this light effectively cover?\u003c\/h3\u003e\n\u003cp\u003eThe 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.\u003c\/p\u003e\n\u003cul\u003e\n  \u003cli\u003eCore high-intensity coverage: 3 x 3 ft (recommended for flowering)\u003c\/li\u003e\n  \u003cli\u003eMaximum spread: up to 4 x 4 ft depending on hang height and crop\u003c\/li\u003e\n  \u003cli\u003eBar-style layout reduces center hotspots, improving uniformity\u003c\/li\u003e\n\u003c\/ul\u003e\n\n\u003ch3\u003eWhat spectrum and diodes does it use, and why does that matter?\u003c\/h3\u003e\n\u003cp\u003eThe 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).

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.\u003c\/p\u003e\n\u003csection class=\"product-faq-snippet\"\u003e\u003ch3\u003eFAQ\u003c\/h3\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: What coverage does the FC-4800 recommend for flowering?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: Use the FC-4800 over a 3x3 ft area for intense flowering; it can extend to 4x4 ft at higher hang heights.\u003c\/p\u003e\n\u003c\/div\u003e\n\u003cdiv class=\"faq-item\"\u003e\n\u003cp class=\"faq-q\"\u003eQ: Does the FC-4800 include smart control out of the box?\u003c\/p\u003e\n\u003cp class=\"faq-a\"\u003eA: No. Smart features require the iConnectu Controller (sold separately) to enable Wi‑Fi\/Bluetooth and app control.\u003c\/p\u003e\n\u003c\/div\u003e\u003c\/section\u003e","brand":"MARS HYDRO","offers":[{"title":"Default Title","offer_id":56801827520852,"sku":"B08BLGRZX7","price":489.29,"currency_code":"GBP","in_stock":true}],"thumbnail_url":"\/\/cdn.shopify.com\/s\/files\/1\/1063\/2652\/4244\/files\/mars-hydro-fc-4800-front-view.jpg?v=1786750080","url":"https:\/\/gardenluxe.co.uk\/products\/mars-hydro-fc-4800-evo-480w-led-grow-light-full-spectrum-samsung-lm301h-evo-3x3-4x4-coverage","provider":"Gardenluxe Uk","version":"1.0","type":"link"}
