Will halogen lamp work in metal halide fixture?

Hello, I have some metal halide fixtures in my store that say on it to use a Par30 m130/0 lamp. I have priced out these lamps and they are pretty pricey. I am being told that a halogen lamp will work in these fixtures. Is that true or are they full of it?

Thank you

One might be able to retrofit a fixture by bypassing the ballast, but that would be labor intensive ...

not retrofitting but just the changing to a halogen lamp. I will tell them they are full of it but not looking forward to the price tag with all the lights.

No you may not simply substitute a tungsten halogen (a kind of incandescent) lamp for a metal halide lamp (a kind of mercury lamp) even if it fits in the socket.

It is possible that some halogen lamps may work with some halide ballasts left in place but I don't know what combinations work and the wrong combination could overheat the ballast.

Furthermore, halogen lamps give off much more heat than halide lamps for a given wattage, so if you did bypass the ballast and put in a halogen lamp, you should substitute a lamp of no more than half the wattage to avoid overheating the fixture and possibly causing a fire hazard. (Halogen lamps don't need ballasts.)
The good conscientious technician or serviceperson will carry extra oils and lubricants in case the new pump did not come with oil or the oil was accidentally spilled, so the service call can be completed without an extra visit.
