Grand Series 700

Grand Series 700 is Harvest Master’s high‑output, bar‑style LED fixture built for controllable spectrum and full‑cycle cultivation. It drives up to 700 W with three independently dimmable channels: veg (5000K), bloom (3000K plus 660 nm and 730 nm), and UV (395 nm). The array uses Samsung LM301H and Osram SSL80 diodes totaling about 1,440 emitters. Rated PPF is 1,988 µmol/s at an efficacy around 2.8 µmol/J. The integrated, UL‑certified driver supports daisy‑chain control. The foldable frame measures 112 × 112 × 10.6 cm and weighs roughly 16 kg. Recommended canopy heights are 45–90 cm. Typical coverage is about 152 × 152 cm in flower and 183 × 183 cm in veg, with passive cooling and IP65 protection for humid rooms.
