The HLG Scorpion Diablo V2, offered through HLG UK/EU, is a true flagship in passive-cooled LED grow lighting, designed to deliver maximum yield and efficiency in commercial and home cultivation alike. This powerhouse features six QB648 Quantum Boards packed with nearly 3,888 Samsung LM301B/H and Osram deep-red LEDs, providing a plant‑centric full spectrum at just under 3,700 K with a high Color Rendering Index (~91). In lab testing, the Diablo V2 achieved approximately 2,121 µmol/s PPF with a stellar ~3.0 µmol/J efficacy. While it draws around 715 W from the wall, the inclusion of integrated reflectors boosts canopy-level light delivery by about 10%, optimizing photon utilization despite a slight change in raw efficiency. 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.
