Rock series 150W HPS&MH electronic ballast is designed for horticulture and agriculture.By using patented technology and new designed circuit, the ballast can work reliably and safety at any time.This ballast can be also used for HPS MH CMH street light.
The increased packing density of components on the printed circuit boards leads to increasingly smaller conductor track spacings. Therefore, the CTI value in the base material data sheets gets more important. This is the index for tracking resistance.
