Lientec LED’s 150W Quantum Gro-Board refers to the single‑board 320‑XL kit driven by a Mean Well XLG‑150; the actual draw of this setup is specified as 140 W. The 320‑XL uses 320 Samsung diodes (LM301H or LM561C, depending on version) on a thick MCPCB for passive cooling and comes dimmable. Lientec lists the effective coverage for this board size at about 60×60 cm for bloom and up to 80×80 cm for veg. Electrical specs on the PDP cite 42–54 V DC and PPE around 2.6–2.8 µmol/J, varying with chipset. The kit typically includes hanging hardware, a dimmer, and EU mains lead.
