FOHSE’s Aries PRO is a tunable-spectrum LED fixture designed for high-intensity single‑tier or homegrow rooms. The current model is a 660 W system with seven independently addressable channels (including UVA, blue, green, cool white, warm white, 660 nm red, and 730 nm far‑red) for precise spectrum control. FOHSE lists photon output options up to 1,866 μmol/s and efficacy up to 2.92 μmol/J, with PPFD mapping available through their light‑planning tools. The PRO line integrates a 4‑in‑1 sensor (temperature, humidity, CO2, and PPFD) and pairs with FOHSE’s PRO controller. The fixture uses passive cooling and is rated for harsh grow environments, with L90 at 50,000 hours noted by the manufacturer. A smaller physical footprint versus earlier designs supports tight single‑tier canopies without sacrificing intensity.
