CMH technology creates high energy PAR/PPF levels with low heat at full spectrum which is closer to sunlight and produces healthier plant growth and larger yield. With a CRI (Colour Rendering Index) of >90%, CMH is perfect for growing high quality produce and essential oil extraction. 

The Lumatek 630W Double-Ended (DE) Ceramic Metal Halide (also known as CMH) lamps are available in 4200K Daylight and 3100K Agro CCT formats.

Double-ended CMH lamps can be more stable than traditional, single-ended Metal Halide (MH) lamps and this allows them to have an increase in light intensity and PAR/PPF output of up to 50% compared with similarly powered standard M.H. lamps.
