CDM Bulbs

Ceramic Metal Halides (CDM) also known as Light Emitting Ceramic (LEC) and Ceramic Discharge Metal Halide (CDM), are the newest innovation in HID lighting. 315W lamps come in two versions, the 3,100 Kelvins (full spectrum) and the 4,200 K (blue spectrum) and bring many benefits to the table, with little to no drawbacks, which is why most growers are changing to these. They currently have the best PAR spectrum of any HID lamp, the slowest degradation rate, and they are at least 10% more efficient than all other HID lamps. By comparison, HPS and MH lights waste a lot of energy producing light at ranges that are not efficiently used by plants. Furthermore, CDM bulbs emit light in the UV spectrum, which will increase essential oil production and aroma in plants. Overall, this makes the CDM bulb a better single light solution that increases the growth, overall health and yield of your plants.
