The HLG 350R is a high-performance Quantum Board LED grow light designed to efficiently replace traditional 600 W HID systems while consuming just around 330 W of power. It features two advanced Diablo boards equipped with high-efficiency Samsung LM301H diodes and 660 nm deep-red LEDs, delivering a true full-spectrum output ideal for both vegetative and flowering phases. This fixture produces over 950 PPF with a stellar efficacy of around 2.80 µmol/J, offering commercial-grade performance in a compact, passively cooled design. It draws between 60 and 330 W, auto-sensing 120‑277 VAC input, and supports dimming via a built-in dial or external controller, offering flexibility for growers tailoring light intensity. But if you’re thinking about another more powerful or a different lighting system, then check out the HLG 650R or even the HLG Scorpion Diablo V2.
