  • Even Light Distribution: Specifically designed to provide uniform levels of photosynthetic flux density (PPFD). Its 8-bar configuration allows installation in low rooms, vertical racks, over rolling benches or even in tents. For maximum uniformity, the fixture should be hanged 24-36 inches from the crop.

  • Integrated Driver Box, No-Fan Design: Features a built-in driver, all in a single design for easy installation and reduced labor cost. Thanks to the no-fan design, there are no noise or moving parts to worry about. Uses a thick, sturdy 2.8 Inch (70mm) aluminum heatsink for optimal heat dissipation.
