If you’re ready to see commercial scale results, it’s time to step up to Black Dog LED!
Perfect for Smaller Grows
At 421 actual watts and 641 μMol/s total photon flux, the patent-pending PhytoMAX-2 400 LED grow light are compact and powerful, outperforming 600W HPS bulbs..
Most powerful and reliable, truly full-spectrum (365-750nm, UV to NIR) LED plant grow lights.
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!
A free pair of Black Dog LED heavy duty ratcheting grow light hangers are included with every PhytoMAX-2 200 light!
Industry-Leading 5 Year Warranty on these grow lights online
MADE IN THE USA
More efficient and powerful than any 600W HPS
PhytoMAX-2 400LED 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 The PhytoMAX-2 400 LED grow lights offer incredible coverage and results with very low electrical requirements!
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 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
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
Once you grow with PhytoMAX-2 commercial LED grow light panels, you'll understand why people say HID is a thing of the past!
