HLG Tomahawk 720 LED Grow Light RJ-Manual Dimming | 5x5 ft

HLG 720W Bar-Style LED Grow Light with RJ-Manual Dimming

The Tomahawk 720 RJ-Manual variant runs 0–720W on a 120–277V input. It uses a 5-bar full-spectrum white-plus-deep-red layout. PPF reaches 2,161 µmol/s at 2.87 µmol/J across a 5×5 ft flowering footprint. The 40.75 × 40 × 2.5 in chassis weighs 20 lbs. A remote-mountable driver and integrated asymmetrical reflectors handle PPFD uniformity. UL 8800 and CSA certified with a 5-year warranty.

When the RJ-Manual Variant Beats the Wireless Option

The RJ-Manual dimming variant keeps controller logic local. There's no Access Point to add, no firmware to manage, no mesh network to troubleshoot. The RJ port accepts a manual knob potentiometer or any standard 0–10V external controller. TrolMaster, GrowFlux Universal Dimmers, and Autopilot gear all plug in. Growers typically hang the fixture 8–24 inches above canopy and dim through the cycle. Integrated asymmetrical reflectors do the PPFD-uniformity work.

Key Features

• RJ Port + Manual Knob Dimming: Accepts manual knob potentiometer or any standard 0–10V external controller — TrolMaster, Autopilot, or generic 0–10V gear.
• 2,161 PPF at 2.87 µmol/J: Manufacturer-rated commercial flux on a 720W draw across the 5×5 ft flowering footprint.
• 5-Bar Full Spectrum + Deep Red: Five-bar layout balances white spectrum with deep red diodes for full-cycle veg-to-flower output.
• Integrated Asymmetrical Reflectors: Smooths canopy PPFD uniformity and reduces hot-spotting that flat-bar fixtures show under low ceilings.
• Remote-Mountable Driver: Detached driver pulls heat off the canopy zone — useful in sealed rooms with tight HVAC budgets.
• No Wireless Access Point Required: Standalone control without the cost or firmware overhead of a wireless mesh — simpler choice for small flower rooms.
• UL 8800 + CSA, 5-Year Warranty: Full commercial certification stack — DLC listing is pending per HLG, verify current status before utility rebate filing.
