The lower wattage of our 315W CMH bulb versus the standard 1000W HID bulb translates to less heat being expelled from the bulb and the ability to place the grow fixture closer to the canopy, increasing light intensity and canopy penetration. This double glass jacketed lamp features a bi-pin PGZ18 lamp base and is rated for either open or enclosed fixture use. The ultra-efficient ceramic metal halide system can do the same job as MH and HPS with better results, using less power and emitting less heat. Lightspeed 315W ceramic metal halide bulbs pair well with any bi-pin 315W system, like our Silverstar CMH Reflector 315W Ballast System or the Lightspeed Digital CMH Ballast.
