HLG Scorpion FR Far Red LED Grow Light | 700W, 1,837 PPF, 5x5 ft

HLG QB272 Quantum Board LED Grow Light with 730 nm Far-Red Diodes

The HLG Scorpion FR runs 0–700W on a 120–277V input. It is a Far Red LED grow light delivering 1,837 PPF at 2.62 µmol/joule. Coverage spans a 5×5 ft full-cycle and flower footprint. The Far Red Spec adds 730 nm diodes to the 660 nm reds and white-light QB272 quantum boards. This gives access to the Emerson effect for flowering. The 38.75 × 36.125 × 3.25 in chassis weighs 24.15 lbs and runs passive thermal management.

Why Far-Red 730 nm Earns Its Slot in a 5×5 Bloom Room

Far red at 730 nm triggers shade-avoidance response in flowering plants. It stretches internodes during late stretch and accelerates photoperiod transition. the fixture's QB272 quantum boards spread that contribution across the full 5×5 canopy. Growers typically hang the fixture 14–18 inches above canopy for full-power bloom runs. The fixture works with TrolMaster, GrowFlux, and Autopilot 0–10V dimming gear. Passive cooling means no fans to clean.

Key Features

• 730 nm Far Red Diode Bank: Triggers Emerson-effect flowering response and accelerates photoperiod transition compared to red-only spectrums.
• 1,837 PPF at 2.62 µmol/J: Commercial-tier flux across a 5×5 full-cycle and flowering footprint at 700W draw.
• QB272 Quantum Board Layout: Spreads diode contribution evenly across the canopy instead of single-board hot-spotting.
• 120–277V Input Range: Covers 120V residential, 240V single-phase, and 277V commercial service on a single SKU.
• Passive Cooling: Fanless thermal management with no moving parts in the airflow path.
• TrolMaster / GrowFlux / Autopilot Compatible: Dim via standard external 0–10V style controllers without proprietary gear.
• 38.75 × 36.125 × 3.25 in / 24.15 lbs: Compact bar fixture footprint for the 5×5 flowering coverage class.
