At 800 actual watts, the patent pending PhytoMAX 800 LED grow lights will outperform any 1000W HID light. With PhytoMAX we have delivered the most powerful and reliable, truly full-spectrum (365-750nm, UV to NIR) LED plant grow lights! The new custom housing is designed to better distribute light and dissipate heat, and the PhytoMAX 800 uses the highest-quality, latest-technology, top-bin LEDs to deliver Black Dog LED's proprietary full-cycle Phyto-Genesis Spectrum®. More Than Replaces any 1000W HID (HPS/MH) PhytoMAX 800 LED grow lights produce a superior yield with higher quality flowers Saves on electrical, cooling, reflector and bulb replacement costs 342 High-Output 5-watt LEDs High light intensity crucial for canopy penetration Even coverage eliminates leaf burn and hot spots 800 True Watts - 1710 LED Watts Largest Proven Footprint of any LED Grow Light Research-proven, large, evenly covered footprint (no hot spots) Proven by independent spectroradiometer testing Phyto-Genesis Spectrum® 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) 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 Commercial Grade LED Grow Lights 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 quiet, 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 a PhytoMAX, you'll understand why people say HID is a thing of the past!
