What is a CMH light?
Ceramic metal halide (CMH) grow lights are a relatively new type of HID lighting, and outperform traditional MH and HPS grow lights. The composition of these lights result in a far more efficient operation, a fuller spectrum of light, and lower heat output. These lights are generally more expensive, but pay for themselves in energy cost savings. Many growers are upgrading their standard HID system with a new CMH system for these reasons.
How long do CMH bulbs last?
Another benefit of CMH light bulbs is the longer life span. While MH and HPS bulbs start to lose efficiency and brightness after 10,000 hours, CMH bulbs can last up to 24,000 hours! If you are considering the higher price of CMH lighting, factor in this incredible advance in life span!
