CMH lamps last on average twice as long as MH or HPS lamps.
Higher PAR value
Despite initial cost of investing in CMH lamps, a CMH system will save your money in the long run.
One 315W CMH is equivalent to 700W+ HPS system in terms of yield per watt.
Due to ceramic element, lamp burns much hotter than MH lamps thus producing a light closer to that of natural sunlight.
CMH lamps have better insulating value, they produce lower heat output, and less likelihood of causing leaf burning, and saves you on cooling cost.
CMH lamps can produce light spectrum sufficient to support both the vegetative stage of plant growth as well as its flowering stage.
CMH lamps also emit UV and infrared rays in their wide spectrum, which plants love. The higher amount of UV produces stronger, woodier stalks.

What are CMH lights?
CMH metal halide grow lights are the newest innovation in HID lighting.
CMH lights are made with an arc tube constructed of a ceramic composite instead of quartz or PCA, this allows the tube to reach higher temperature.
The higher operating temperature of the ceramic tube allows for an ideal mixture of gases, and this creates a fuller spectrum of light that increases the growth, overall heath and yield of your plants.
Should I make the switch to CMH setup and what do I expect from switching?
Absolutely, if you are a seasoned grower there is nothing better than having a setup that uses less energy and produces better yields.
Having a CMH setup means you will be running more efficiently in terms of yield per watt. Your energy bill will come down dramatically and you will seeing the savings overtime.
Despite the initial cost, the CMH is newer and also is the latest generation in HID lighting. LEDs cannot produce light spectrums anywhere near HPS/MH lights, and HPS/MH lamps are more expensive to run, thus making CMH an ideal investment.
