The new custom housing is designed to better distribute light and dissipate heat, and the PhytoMAX 400 uses the highest-quality, latest-technology, top-bin LEDs to deliver Black Dog LED's proprietary full-cycle Phyto-Genesis Spectrum™.

  • Replaces 600 Watts of HID (HPS/MH)

    • Saves on electrical, cooling, reflector and bulb replacement costs
  • 182 High-Output 5-watt LEDs
    • High light intensity crucial for canopy penetration
    • Even coverage eliminates leaf burn and hot spots

    • One ideal spectrum for both vegetative and flowering stages eliminates growth stalling associated with spectrum changes such as switching from MH to HPS
    • True full spectrum ranging from UVA to NIR (365-750nm) goes Beyond PAR™ for ultimate flowering and vegetative plant cycles
    • Targets not only photosynthetic (chlorophyll / carotenoid) peaks but also:
      • Increases THC, CBD, terpenes, flavonoids, antioxidants / vitamins and pigmentation with UV light
      • Includes near infrared (NIR) light to boost photosynthetic efficiency through the Emerson Effect

        • Long-Life, Commercial Grade Components

          • No hazardous waste disposal fees
        • Metal adjustable ratcheting 6-foot light hangers
        • Limited Lifetime Warranty
          • The industry's best warranty
