The Meijiu 1978 1000W is a square-format, 8‑bar LED fixture built for high-intensity horticulture across a 1.5 x 1.5 m canopy. It draws 1000 W (±5%) and delivers up to 3000 µmol/s with reported efficacy up to 3.0 µmol/J. The bar array folds for handling and uses top-bin Samsung LM301H whites with Epistar reds, driven by Sosen/Mean Well power supplies. Dimming is 0–10 V in steps (0/25/50/75/100%), and the light supports external controllers via RJ-type connections. Rated IP65 with passive cooling, it weighs 13.5 kg and measures 1060 x 1060 x 32 mm. Designed for uniform distribution at short hang heights, it suits vertical racks, low rooms, and tents where single-source, even PPFD is required.
