At 420 actual watts and 641 μMol/s total photon flux, the patent-pending PhytoMAX-2 400 LED grow lights are compact and powerful, outperforming 600W HPS bulbs. With PhytoMAX-2 we have delivered the most powerful and reliable, truly full-spectrum (365-750nm, UV to NIR) LED grow lights for indoor plants! The PhytoMAX-2 400 uses only the highest-quality, latest-technology, top-bin LEDs to deliver Black Dog Grow Light's proprietary full-cycle Phyto-Genesis Spectrum® evenly over the entire footprint, with unprecedented PAR levels, canopy penetration and yields!

• More efficient and powerful than any 600W HPS

  • PhytoMAX-2 400 LED grow lights better penetrate dense canopies to produce a superior yield
  • Increases yield over a 600W HPS while using 35% less electricity
  • Saves on electrical, cooling, ref

  • More efficient and powerful than any 600W HPS

    • PhytoMAX-2 400 LED grow lights better penetrate dense canopies to produce a superior yield with higher quality flowers and more trichomes
    • Increases yield over a 600W HPS while using 35% less electricity
    • Saves on electrical, cooling, reflector and bulb replacement costs

  • 168 High-Output 5-watt LEDs

    • Every top-bin LED is selected from the industry leader for the particular wavelength, including Cree, Osram, etc.
    • With glass lenses for durability and cleanability
    • High light intensity and energetic spectrum, crucial for canopy penetration to nourish lower leaves and flowers
    • Even, edge-to-edge coverage eliminates leaf burn and hot spots

  • 420 True Watts - 840 LED Watts

  • Large Coverage Footprint

    • Up to 1.3 X 1.3 meters (1.7 square meters!) of flowering footprint coverage!
    • Proven by independent spectroradiometer testing

  • Phyto-Genesis Spectrum®

    • The most efficient spectrum for growing plants, based on over 6 years of research and testing, outperforming HPS, MH, CMH (LEC), induction, fluorescent, and "white", so-called "full-spectrum" LEDs in equal wattage tests
    • One ideal spectrum for both vegetative and flowering stages eliminates 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
    • Appears white to human eyes, allowing easy determination of plant health
    • Targets not only photosynthetic (chlorophyll / carotenoid) peaks but also:
      • Includes near infrared (NIR) light to boost photosynthetic efficiency through the Emerson Effect
      • Decreases internodal spacing to direct more of your plants' energy to flowers and leaves, instead of stems

  • Commercial Grade LED Grow Lights

    • ETL certified to UL safety standards
    • Unique no-glass design delivers up to 8% more light to your plants
    • The best active heat management in the industry, crucial to maximizing LED efficiency, life, and spectrum stability
    • Largest heat sink among commercial LED grow lights for superior cooling and increased LED life
    • Ultra quiet, long-life fans: 70,000+ hour rated lifespan

  • Fast, Proven ROI

    • With a 6-12 month average return on investment, PhytoMAX-2 400 LED grow lights deliver higher yields with 35% less electricity than a 600W HPS

  • Contains no Highly Toxic Mercury

    • Unlike all HID (HPS, MH, CMH / LEC) and fluorescent / induction bulbs
    • No hazardous waste disposal fees

  • Metal adjustable ratcheting 2.4-meter light hangers

  • Industry-Leading 5 Year Warranty

  Once you grow with PhytoMAX-2 commercial grow lights, you'll understand why people say HID is a thing of the past!
