SunFlux’s Samsung Quantum Boards 301h IR+Red 660nm 440W is a dimmable LED quantum-board grow light built around Samsung LM301H diodes, with supplemental 660 nm deep red and far‑red diodes. The fixture draws approximately 440 W (+/−10%) and ships assembled with hanging hardware and a Mean Well driver. It outputs a broad, full‑spectrum white centered at 3500 K with a 120° beam angle to support vegetative and flowering growth. The 440 W model measures 600 × 480 × 55 mm and uses a total of 1,000 LEDs, delivering around 1000 μmol/s PPF at up to 2.7 μmol/J efficacy. Product weight is listed at 10 kg.
