    PhytoMAX-2 800 LED Grow Light
    • At 840 actual watts and 1282 μMol/s total photon flux, the patent-pending PhytoMAX-2 800 LED plant grow light will outperform any 1000W HID light. With PhytoMAX-2 we have delivered the most powerful and reliable, truly full spectrum grow light for optimal results (365-750nm, UV to NIR)! The PhytoMAX-2 800 uses only the highest-quality, latest-technology, top-bin LEDs to deliver Black Dog LED'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 single-ended (SE) HPS
    • PhytoMAX-2 800 LED plant grow lights better penetrate dense canopies to produce a superior yield with higher quality flowers and more trichomes
    • Increases yield by 30% or more over a 1000W HPS
    • Saves on electrical, cooling, reflector and bulb replacement costs
    336 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
    840 True Watts - 1680 LED Watts
    Huge Coverage Footprint
    • Up to 6' X 6' (36 square feet!) 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:
      • Increases 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
    • Ultra quiet, long-life fans: 70,000+ hour rated lifespan
    Fast, Proven ROI

    I've had the original phytomax 800 for a year and a half...I recently snagged this phytomax 2 800 and running a side by side with GSC forum cut and the new phytomax2 is completely shredding the original phytomax..WAY TIGHTER NODE SPACING..and the bud size is already twice the size and I'm only 5 weeks in..don't get me wrong I LOVE the original phytomax...but these guys really outdid themselves with the new phytomax2s..these lights are gonna change the game


    I have Kind, and I like them. Then I bought a Black Dog Max 2 800. No comparison. The Black Dog is WAY BETTER in every way. No hot spots or shadowy corners, it has a huge footprint, and it's cooler than the Kind (bigger heat sink, and it helps a lot!) This light is no joke, and I will be buying more of them as soon as possible. My plants LOVE the Black Dog, and so do I!
