Once you grow with Black Dog PhytoMAX-2 commercial grow lights, you'll understand why people say HID is a thing of the past! This is one of the most powerful 400 Watt LED Grow Lights available.
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 Black Dog Grow Light'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 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
420 True Watts - 840 LED Watts
Large Coverage Footprint
- Up to 4.25’ x 4.25’ (18 sq ft) / 1.3m x 1.3m (1.7 sq m) of flowering footprint coverage!
- Proven by independent spectroradiometer testing
- 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
- 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
