3.When the high pressuremercury lamp, high pressure sodium lamp and Matallic Halide lamp is selected by custom who need equip relevant flameproof ballast box.
5.Also,on the basis of mercury injection experiment,the capillary pressure data vs.aperture distribution by CMR were studied,which laid a basis for applying T 2 spectrum to inversing capillary pres-sure curves.
8.There are basically three types of HID lights. Mercury vapor (MV), metal halide (MH), and high pressure sodium (HPS). These lights also require a starter and a ballast.
9.For the purposes of growing marijuana, there are two basic types of lights: fluorescents and high intensity discharge (HID), including MV (mercury vapor), MH (metal halide), and HPS (high pressure sodium).
