Meijiu X 320H V3 LM301H Quantum Board is a 320 W LED fixture built around three high‑efficiency white quantum boards using Samsung LM301H diodes, supplemented with 660 nm deep red, 730 nm far‑red, and 395 nm UV for a full, cultivation‑oriented spectrum. The kit includes a Mean Well 320 W driver with 0–10 V dimming in a passively cooled layout. Meijiu specifies a flowering footprint of 2' x 4' (up to 2.5' x 5') and a veg footprint of 3' x 5'. Total photon output is listed at 720 µmol/s with system efficacy around 3.0 µmol/J. Recommended mounting height is 18–24 inches. Rated LED lifetime is up to 50,000 hours, suiting single benches, low rooms, and typical 2 x 4 ft tents.
