Ceramic Grow Lights Vs Hps

Hps is more efficient but lec provides a wider more natural spectrum of light.

Ceramic grow lights vs hps.

Cmh grow lights also go by the name ceramic discharge metal halide cdm the lights use ceramic technology and they have the qualities of metal halide and hps grow lights. Cmh short for ceramic metal halide emits highly intense lights similar to hps grow lights. Commercial gardeners who would benefit by standardizing on a single bulb technology may prefer lec. Instead of using a quartz tube they use a ceramic one more here similar to an hps bulb.

Those on a tight budget who want to use a proven light tech involving great efficiency may opt for hps. Sure there are a few downsides to using cmh bulbs but this is the case for every type of bulb. Cmh grow lights are a variation of mh but they are quite different. The 600 watt ceramic hps rather produces the same amount of total overall light energy as the traditional 600 watt hps but it is spread over a broader range of the spectrum that does not get measured by a lumen meter.

A cmh uses a ceramic arc tube similar to those used in hps grow lights instead of the quartz used in traditional metal halide grow lights. They are saying the amount of light energy in the 350 1100nm range of the 600w ceramic hps is the same as the light energy that a regular 600w hps has in it s 350 1100nm range. Ceramic hps produces vibrant colorful plants which stay strong and healthy throughout the flowering stage. The ceramic arc tubes operate at higher pressures than quartz glass tubes which enables manufacturers to make more precise variations on the spectrum than with previous technologies.

This allows a higher arc tube temperature which in turn allows a better mix of gases to produce a more optimal spectrum more on this below in the sections comparing cmh to mh and hps. The ceramic hps is a strong start to finish grow light as well and produces healthy vegetative plants ready for transition to stronger light sources. The lights use ceramic arc tubes very similar to the tubes in hps grow lights.
