• 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!

* Average PPFD measurements are over the entire footprint, edge-to-edge and corner-to-corner, based on reflective surroundings or adjacent lights.
** When growing in an area smaller than the Medium Recommended Flower Footprint, CO₂ supplementation is generally required to make full use of the additional light.
