The 315W Ceramic MH Lamp is a high-efficiency, full-spectrum metal halide grow lamp that provides vigorous growth during veg and increased resin production during flower. Closely mimicking real sunlight and operating at a color temperature of 3000K, its balanced spectrum supports exceptional development in all stages of growth — covering an area of approximately 3ftx3ft in veg and 2.5ftx2.5ft in flower. It operates with high PAR efficiency and produces less heat than traditional MH bulbs, allowing for closer canopy placement and improved light penetration. With up to 20,000 hours of lifespan, it ensures consistent, reliable performance across multiple grows. If you’re looking for something with more wattage for larger spaces, the 400W Metal Halide covers up to 4ftx4ft in veg with increased light intensity. For smaller setups check out the 300W by Vivosun.
