Description
Philips 315W CMH lamps are used in all of the Maxibright 315W CMH Lighting Kits that we sell, and are also used in some other grow lights from companies such as Dimlux.
They are pretty much the industry standard 315W CMH, or CDM, lamps for growing plants. Other 315W CMH/CDM lamps are available but emit quite different spectrums, they are not as effective for plant growth.
