Meijiu’s MJ A320 with UV IR is a 320 W foldable, multi-bar LED grow light built around a square 600 × 600 mm frame for compact tents and multilayer racks. The fixture uses top-bin Samsung and Epistar diodes, integrates UV and IR, and is driven by a Turefull 0–10 V dimmable driver. It is rated at up to 2.6 µmol/J efficacy with a PPF of 832 µmol/s, and is optimized to deliver uniform PPFD over a 90 × 90 cm footprint. The six passive-cooled LED bars feature clear-glue encapsulation for high transmittance and IP65 protection.
