What is Ceramic Metal Halide Lighting Systems?
Ceramic Metal Halide Crop Lighting Systems AKA " CDM" " LEC" "CMH" are gaining popularity with indoor growers looking to maintain very high quality crops of respectable yields while drastically reducing electrical consumption for the same sized crop lighting foot print versus 600W or Conventional 1000W HID lighting systems operating High Pressure Sodium lamps.

Advantage:
UL No.: E485515

Patent: Smart digital control light source auto-adapt light decay technology

330w Low Frequency,Square wave,Soft start,grow light Ballast.
With short-circuit,circuit overheat,Lamp-failure protection,etc.
Close to the sunlight,energy saving more than 25%.
Match well with Philips CMH,CDM bulbs.
Dimmble(with LED display)

Support Lamp Type: Ceramic metal halide(CMH),MH/QMH.

    HPS                   400W,360W

5 years lifespan or more.
3 years warranty.

As you can see, the color from CMH is more abundant than HPS, MH and LED, which is very suitable for plant growth, and operational efficiency is better than HPS and MH as the spectrum is closest to nature sunlight.
