The HLG QB96 Elite V2 offered by HLG UK/EU is a high-intensity, compact Quantum Board® engineered for experienced growers and DIY enthusiasts seeking powerful yet space-efficient lighting. At roughly 95 x 70 mm, each board integrates 64 high-power white Samsung LEDs along with 16 red (630 nm) and 16 deep-red (660 nm) diodes, creating a broad, boost-red-infused spectrum ideal for all growth stages including flowering. At a factory test of 56 V and 4 000 mA, it delivers about 224 W with efficacy around 2.25 µmol/J, and at lower currents (~1 400 mA) reaches up to 2.6 µmol/J efficiency. In real-world setups, many growers run two boards off a single HLG‑320H driver, achieving ~350 W wall draw and covering ~3 x 3 ft or even 2 x 4 ft areas. 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.
