The HLG QB132 V2 by Horticulture Lighting Group is a compact yet powerful Quantum Board designed for DIY growers and small-scale cultivation setups. Each board measures approximately 300 × 225 mm and contains 132 top-tier Samsung LM301H LEDs. These boards are engineered for high energy efficiency, delivering outstanding performance without the need for heatsinks or thermal paste. Each QB132 V2 board operates at up to 36 V DC and supports a maximum current of 2,100 mA, which translates to roughly 75 W per board, making it ideal for vegging, cloning, or serving as supplemental lighting in flowering phases. But if you’re thinking about another more powerful or a different lighting system, then check out the HLG 300 V2 Rspec or even the HLG 550 V2 Rspec.
