HLG Tomahawk 650 LED Grow Light with GrowFlux Wireless | 650W, 5x5 ft

HLG Tomahawk 650 Output, Bars and Build This fixture draws up to 650W and spreads its diodes across 5 bars. It is rated at 1,920 µmol/s and 2.94 µmol/J. The diodes pair full-spectrum white with 660 nm deep red. Each bar sits in an integrated asymmetrical reflector that turns more of the light down onto the canopy. The driver accepts 120–277V and can be mounted remotely to move heat out of the tent. The frame measures 40.75 x 40 x 2.5 in and weighs 20 lb. Cooling is passive, and the open bar layout lets air move straight through. Expect about 2,218 BTU/hr of heat at full power. It carries UL 8800, CSA and DLC listings with a 5-year warranty. Controlling the Light Through GrowFlux Wireless GrowFlux wireless replaces the dimmer knob with app control over a mesh network. From a phone you can dim the light, set schedules and tie output to a PAR sensor. The GrowFlux access point is sold separately, and one access point can run many HLG lights at once. That makes this version the better pick when several tents or rooms need to ramp together. Flower coverage is 5 x 5 ft. Hang it between 8 and 24 inches above the tops, starting high and lowering as the canopy fills. Bring intensity up over the first weeks of flower and watch the upper colas for bleaching. LED puts less radiant heat on leaves than HPS, so many growers raise room temperature a few degrees. The spectrum has no UV or far-red channel, so add those separately if you want them. If you run a single tent and never plan to automate, the RJ manual-dimming version saves the cost of the access point. Key Features Five bars, 650W: About 1,920 µmol/s at 2.94 µmol/J. Integrated asymmetrical reflectors: Push more light onto the canopy and reduce hot spots. GrowFlux wireless module: App dimming, schedules and PAR sensor control; access point sold separately. Remote-mountable driver: Moves driver heat outside the tent on 120–277V. Open, passive design: No fans, 20 lb frame, air flows through the bars. UL 8800, CSA, DLC: 5-year HLG warranty.
