At 420 actual watts and 641 μMol/s total photon flux, the patent-pending PhytoMAX-2 400LED 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 our 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 for indoor plants 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
    • LED grow lights save 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 4.25' X 4.25' (18 square feet!) of flowering footprint coverage!
    • Proven by independent spectroradiometer testing
  • Phyto-Genesis Spectrum®
    • The most efficient light 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:
      • 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
      • Decreases internodal spacing to direct more of your plants' energy to flowers and leaves, instead of stems
  • Commercial Grade LED Grow Light Panels
    • 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 8-foot light hangers
  • Industry-Leading 5 Year Warranty

Once you use PhytoMAX-2 LED grow lights for indoor plants, you'll understand why people say HID is a thing of the past!
