Smartlight Ceramic Metal Halide 630w/3200k Double Ended Lamp

CMH lamps are a broad spectrum "white" lamp. MH lamps are predominantly blue spectrum focused

and HPS lamps are red/yellow focused. A CMH lamp has 2.5 

times the blue light than that of a HPS lamp. The 13.4% blue light from CMH lamp is slightly higher than a 50/50 mix of 

HPS & MH lamps. 

A CMH lamp has a more uniformed spectral output than any other  lamp used for plant growth lighting, which is ideal if growing for medicinal use as there is a significant increase in oil production. 

CMH lamps are suitable for cloning, vegative growth and flowering stages.

Lamps come with a 6 month replacement warranty - conditions apply
