AC Infinity IONBOARD S44 400W Full Spectrum LED Grow Light

High‑efficiency full‑spectrum LED delivers 2.75 µmol/J uniform canopy coverage for bigger yields and lower power use. The AC Infinity IONBOARD S44 is the ultimate grow light for serious cultivators. Designed with Samsung LM301H diodes, it provides an optimized spectrum, uniform PAR coverage, and deep canopy penetration for maximum plant yields. The fanless aluminum board ensures efficient heat dissipation, while the IP-65-rated build withstands high humidity and heat. Smart dimming, Wi-Fi connectivity, and daisy-chain expansion make it a future-proof investment—perfect for grow tents, hydroponics, and large-scale setups. Is the IONBOARD S44 Energy-Efficient? Absolutely. At 2.9 µmol/J, this grow light outperforms traditional HPS systems (1.8–2.1 µmol/J) while consuming less power. That means more grams per watt, reduced cooling costs, and a more sustainable grow operation. Whether you're cultivating in a 4x4 grow tent, vertical farm, or greenhouse, the IONBOARD S44 maximizes your ROI wi
