and bulb of course the transformer is the same right
Can I convert a Mercury Vapor ballets to HPS by Changing the ignitor/starter?
Mercury and Metal Halide Lamps have an additional electrode located at one end of the arc tube to assist in lamp starting. These types of lamps require an open circuit Voltage(O.C.V.) approximately two times the lamp voltage to initiate and sustain the arc.
High Pressure Sodium Lamps and some newer Metal Halide lamps,however,have no starting electrodes. In addition to an O.C.V. of approximately two times the lamp voltage, these lamps are started by a high voltage starting pulse, provided by an ignitor, applied across the arc tube.
Most Mercury lamps are designed to start at 240 or 277 volts, the reactor ballast is the most economical way to ballast a Mercury lamp in systems operated at either of these two voltages.
I would suggest that you contact Advance Transformer Co.
