Meijiu 1988 650W is a foldable, 8‑bar LED grow fixture designed for uniform coverage across a 1.5 × 1.5 m canopy. Drawing 650 W (±5%), it outputs up to 1836 µmol/s at a peak efficacy of 2.8 µmol/J, using top‑bin Samsung and Osram diodes. The bar layout spreads PPFD evenly at short hanging distances for tents and single‑bench rooms. It supports 0–10 V dimming with OFF/25/50/75/100% steps and works with compatible external controllers. Build highlights include IP65 ingress protection, passive cooling, and a stated lifetime of 50,000 hours. The fixture measures 1060 × 1060 × 32 mm, weighs about 9.5 kg, and commonly targets a 5 × 5 ft footprint; retailers also note 660 nm deep‑red supplementation for balanced, full‑spectrum output.
