The HLG 300L Rspec by Horticulture Lighting Group (HLG) is a top-tier Quantum Board‑style LED fixture designed as a direct replacement for 600 W HID grow lights. It features two large Samsung LM301H white-light boards enriched with 660 nm deep-red LEDs per board, delivering a full-spectrum output optimized for all stages of plant growth. This fixture operates efficiently within a power range of 30–250 W, drawing from a universal 90–277 VAC supply. It produces approximately 679 PPF with an impressive efficacy of around 2.7 µmol/J, an energy-conscious powerhouse for your grow space. Equipped with a high-quality internal Mean Well 240H‑C2100A driver, the fixture auto‑senses between 120 VAC and 240 VAC power and features a 0-10 V dimming interface. 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.
