Ceramic Metal Halide Lighting (CMH)
Ceramic Metal Halide Lights, or CMH lights, are relatively new to the market. Providing the same output as comparable incandescent bulbs, CMH bulbs only require roughly 20% of the power. You should try out a CMH system if you are looking to save on electricity costs. CMH lights are also known to retain their color spectrum longer than their incandescent and MH counterparts, making them last much longer and making them optimal for use in indoor growing setups.
