 - "New and improved for 2017, 60% more light than its predecessor!"

Designed to maximize yields, PhytoMAX-2 is setting the new standard for power and efficiency. With 60% more light at the same wattage, the development of PhytoMAX-2 is the greatest advancement the growing world has ever seen. Black Dog LED has delivered the most powerful, reliable and truly full-spectrum line of LED grow lights (365-750nm, UV to NIR) since the beginning of the industry! The new custom housing is designed to better distribute light without the light-robbing glass cover and dissipate heat with the new quieter fans. Black Dog LED PhytoMAX 400 only uses the highest-quality and latest-technology top-bin glass lens LEDs to deliver their newly improved proprietary full-cycle "Phyto-Genesis Spectrum™."
