  • 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

In The Box

  • [1] x Black Dog LED - Phytomax-2 LED Grow Lights - 400 | True Watt: 420W

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:
    • 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 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
  • Whisper-quiet, long-life fans: 70,000+ hour rated lifespan


Contains no Highly Toxic Mercury

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

3-Year Replacement Warranty

  • If the product is faulty within the warranty period, the product will be replaced with a new one.
