The HLG 750 Diablo (also known as the 750 Rspec in UK/EU markets) is Horticulture Lighting Group's flagship lighting solution for serious growers aiming to replace 1000 W HID setups with a highly efficient LED fixture. Powered by four high-performance Diablo Quantum Boards®, it delivers an outstanding 2,056–2,089 PPF output at an impressive ~2.86–2.88 µmol/J efficacy. Built for large-scale operations, its coverage includes a 5' × 5' flowering footprint at 15–24" hang height, expanding to 6' × 6' for vegetative growth at 30–36". The fixture spans 37.5" × 27.125" × 3.75", weighing ~20 lb, and features integrated reflectors that boost deep-canopy penetration. 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.
