The patent pending PhytoMAX 400 is a compact and powerful 425 watt LED grow light that will outperform any other equal-wattage LED grow light on the market. Do a side-by-side for yourself with our 90-day no hassle return policy!
With PhytoMAX we have delivered the most powerful and reliable, truly full-spectrum (365-750nm, UV to NIR) LED plant growing lights! The new custom housing is designed to better distribute light and dissipate heat, and the PhytoMAX 400 LED growing lights use the highest-quality, latest-technology, top-bin LEDs to deliver Black Dog LED's proprietary full-cycle Phyto-Genesis Spectrum®.
Replaces 600 Watts of HID (HPS/MH)
Producing a superior yield with higher quality flowers
Saves on electrical, cooling, reflector and bulb replacement costs
182 High-Output 5-watt LEDs
High light intensity crucial for canopy penetration
Even coverage eliminates leaf burn and hot spots
425 True Watts - 910 LED Watts
The PhytoMAX 400 will outperform any other equal-wattage LED grow light on the market!
Largest Proven Footprint of any LED Grow Light
Research-proven, large, evenly covered footprint (no hot spots)
Proven by independent spectroradiometer testing
The most efficient spectrum for growing plants, based on over 5 years of research and testing, outperforming HPS, MH, CMH (LEC), induction, fluorescent, and "white" LEDs in equal wattage tests.
One ideal spectrum for both vegetative and flowering stages eliminates growth 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
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
ETL certified to UL safety standards
The best active heat management in the industry, crucial to maximizing LED life, efficiency and spectrum stability
Largest heat sink among LED grow lights for superior cooling and increased LED life
Ultra efficient, long-life fans: 70,000+ hour rated lifespan
Fast, Proven ROI
With a 6-12 month average return on investment, PhytoMAX is the best value per watt of any commercial LED grow light
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
Limited Lifetime Warranty
The industry's best warranty
Once you grow with PhytoMAX LED growing lights, you'll understand why people say HID is a thing of the past!
