DescriptionPhytoMax-2 400 LED Grow Light
- 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 our proprietary full-cycle Phyto-Genesis Spectrum® evenly over the entire footprint, with unprecedented PAR levels, canopy penetration and yields!
- 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
- 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
Large Coverage Footprint
- Up to 4.25' X 4.25' (18 square feet!) of flowering footprint coverage!
- Proven by independent spectroradiometer testing
- 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 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
- 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
- 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

FREE pair of Black Dog LED heavy duty ratcheting grow light hangers are included with every PhytoMAX-2 400 light!
I purchased a Phytomax 400 about 4 years ago. I noticed that one of the light banks had stopped working during my last flowering period. I contacted Black Dog, and they made the repairs pain free! The entire process took less than two weeks and my light is back up and running again! This little light kills it every time Ive used it!
I had done hours of research before l made the purchase. My Kind 600 is gathering dust in the corner. Lack of density, frost and depth of light penetration. Black dog lights DUMP par! So went on and purchased this 400....AND THEN ANOTHER! I no longer worry about light intensity. Did l mention lowers are as frosty and dense as tops!?!
