CMH Grow Lamps Require Less Electricity

December 14, 2018

Newer CMH lamps require less electricity to generate more usable light output, so you can use a lower-wattage lamp than you might with an HPS or an MH lamp. CMHs are thus more efficient than standard MH lamps, and they put out less heat than HPS lamps, which is a great benefit to most home growers.

With a more full-spectrum light output and a 20,000-hour life span, a CMH lamp is a quality all-around HID lighting solution for home gardeners who want to grow a variety of plants indoors without switching lamp types.
