Switching from a 1000 watt high pressure sodium or metal halide system to a Lightspeed 630W ceramic metal halide system will increase the growth, health, and yield of your plants and will lower your energy costs by up to 70%. The wide spectrum of our Lightspeed CMH bulbs allows either the 3100k or 4200k to be used from the vegetative phase straight through to flowering, or for maximum growth and yield begin with the 4200k bulb for vegetative and then switch to 3100k for the flowering phase.

The lower wattage of our 630W 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 double ended lamp base and is rated for open 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 630W ceramic metal halide bulbs pair well with any double ended 630W system, like our Lightspeed CMH DE 630W System or the Lightspeed Digital CMH 630W Ballast.
