The HLG 350 Diablo (HLG 350R) Commercial Indoor Horticulture LED grow light is designed to replace a 600 watt HID with just 330 Watts.
Each HLG 350R uses (2) HLG custom-designed, full-spectrum, high-efficiency Diablo™ quantum boards with Full Spectrum White & Deep Red LEDs.
With its rectangular footprint and integrated reflectors, this fixture is ideal for flowering in smaller grow spaces or vegging in a commercial grow. Integrated reflectors improve photon delivery resulting in higher quality yields even at the lower levels of the canopy. This incredibly efficient full spectrum horticulture lamp has an efficiency of 3.11 PPF/W.
