The main Point of the MV Light is the Ballast
with a MH buld and a capicitor, and a little research
you could have a MH light cheap.
(we also know that a MH bulb will work in our MV light, but with some Ignighter problems)
You could also make this light switchable to HPS.
Yes again with a little research, and the right Capicitor
and Ignighter you now have a HPS Light.

It all depends on what kind of ballast you have to begin with
CWA - Constant Wattage Autotransformer
lag circuit
Lead circuit

Metal halide lamps have an operating voltage close to that of mercury lamps in many wattages, but have stricter tolerances for wattage and current waveform. Metal halides also usually need a higher starting voltage. Most metal halide lamps 100 watts or smaller require a high voltage starting pulse around or even over 1,000 volts.175 to 400 watt metal halide lamp ballasts can power mercury lamps of the same wattage, but the reverse is not recommended. Mercury lamps 50 to 100 watts will work on metal halide ballasts, but hot restriking of mercury lamps 100 watts or smaller on metal halide lamps may be hard on the mercury lamp since the starting pulse can force current through cold electrodes and the starting resistor inside the mercury lamp.
