Hydro Crunch 315-Watt Ceramic Metal Halide (CMH) Lamp

CMH grow lights bring the benefits of growing in natural sunlight into your indoor grow environment to help your plants reach their optimal growth potential without the use of supplemental lighting. CMH lighting is favored by many growers for its high energy output, efficiency, and durability. Your plants will enjoy a wide, consistent spectrum of light. CMH lamps emit a crisp light that promotes photosynthesis and supports them throughout the various growth stages from cloning to flowering. These lamps run cooler due to their low wattage. That means less cooling costs for you. They have a long life span - 20,000 hours or longer -  more than double that of HPS and MH.   Specs Full-spectrum: For both flowering and vegging stage Initial lumen: 33000 Average life span:  20, 000-hours or more Temperature color: 3100K or 4200K CRI: 90 crisp  Base Type: PGZ18 PAR value: 570 mol/s Manufacturer Warranty 1 year warranty against manufacturer defect.
