Ceramic metal halides, also called light-emitting ceramics, are the newest innovation in HID lighting. They bring many benefits.

What are Ceramic Metal Halide Grow Lights?

CMH metal halide grow lights are made with an arc tube constructed of a ceramic composite instead of quartz or PCA. This allows the tube to reach a higher temperature. To achieve the lower operating temperature in HID lamps made with quartz or PCA, a combination of gases must be used that don’t necessarily produce the optimal light spectrum for photosynthesis.

The Benefits of CMH Grow Lights

CMH grow lights provide a broad spectrum. Because CMHs mimic the sun, your plants receive a broad spectrum of light. Your plants will receive UV light from these grow lights. Ultraviolet light offers your plants many benefits. These include faster photosynthesis for plant growth, increased flavor, and better pest control. 

CMH kits produce less heat than HPS/MH grow light kits. Though HPS/MH grow lights are great for many growers'indoor tent setups, they’re notorious for generating a lot of heat. These kind of indoor grow lights produce less heat. This is great for overall climate control in your grow room, and it prevents your plants from becoming burned or receiving other types of heat damage.

CMH grow lights emit every color on the spectrum, whereas LED grow lights do not. They also have a higher CRI value than LEDs.

The intensity of light given off by CMH lights is greater than that of LEDs. However, this means that they use more power and are less energy-saving.

LEDs are not as high intensity as CMH grow lights. However, these lights can last up to 50,000 hours before the bulbs need replacing. That means that if the light is used for 12 hours every day, it will last you 11 years.
