The HLG 650 R was engineered to fully replace a 1000 W double-ended HID lamp while drawing just ~650 W. It delivers a massive 1,781 PPF with an exceptional 2.84 µmol/J system efficacy—offering class-leading photon output per watt. This dimmable fixture uses four high-density QB648 “Diablo” Quantum Boards populated with hundreds of Samsung LM301H white LEDs and deep-red 660 nm diodes. Thanks to this advanced diode array, it generates deeper canopy penetration and broader footprint coverage than its predecessors. With total output around 1,770 PPF at 630 W, and a dimming range spanning 160–630 W, the 650 Rspec adapts easily to all crop stages. 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.
