Compared with traditional magnetic ballast,this unit-HID Electronic Ballast can reduce the current at least 60%,and save energy more than 30%.It has a wide working rang-e.When voltage of the electric net changes from 25% to +15%,the output wattage is un-changed,and the bulb can work with changeless status.The luminescence is steady wit-hout flames,and the life is lengthened.It has many protective functions.It can prevent accidents from open circuits,short circuits,damages,gas leakages,etc.You don’t need to add any trigger or supplemental capacitance.It is light,expedient and longevous.
     Adapted to high pressure sodium lamp and metal halide lamp,this product has compl-eted specifications and types.You can select single output(one ballast support one bulb) or multi-output(one ballast support several bulbs).That makes user more expedient.
