FOHSE’s A3i Pro is a 1,500 W industrial LED fixture built for high‑bay, single‑level cultivation. It adds seven isolated spectrum channels—UVA, Blue, Green, Cool White (6500 K), Warm White (2700 K), Red (660 nm) and Far Red (730 nm)—and integrates temperature, humidity, CO2 and PPFD sensing for on‑fixture monitoring. FOHSE lists photon output up to 4,359 μmol/s PPF, and its A3i platform demonstrates coverage up to 5.5 × 5.5 ft per fixture, supporting fewer fixtures per canopy compared with legacy HPS layouts. The Pro shares the A3i’s large form factor at approximately 117 × 117 × 10 cm and about 37 kg. Designed for robust cross‑illumination via swiveling light bars, the A3i Pro targets uniform canopy intensity with tunable spectrum throughout the crop cycle.
