CMH Ballasts

A CMH ballast is responsible for starting and regulating the current in your CMH grow light. Without regulation, the CMH bulb would burn too bright and "pop", or not start at all.A special ballast is needed for ceramic metal halides. Not just any digital ballast will do. CMH lamps require a low frequency, which makes high-frequency digital ballasts incompatible.
