The 250 watt MH ballast installed in M-250 R1.
This is how I installed the ballast in the fixture. Tight squeeze, but it works nicely.

The light gets hot when it's on but it could be a heater for the winter. xD

Looks like a neat and tidy installation. Cool

The capacitor is a teeny but loose, but it's alright. So even though this was originally a pulse start metal halide ballast, at 250 watts taking the ignitor off and running a probe start ballast isn't bad? I would hope not. The ballast was originally from a high bay with a huge reflector. Ballast is big, kinda heavy, but it seems to hold up pretty well. I hope it doesn't fail on me soon.

I don't think there would be any issues, but i can't say with 100% certainty. As long as you don't run it constantly (no more than a few hours a day). Do you have a 250W MV lamp? Maybe see how that runs instead? I think PSMH ballasts have a higher OCV then MH ballasts so the lamp might be getting a higher arc voltage (which would probably throw the color off, either make it bluer or yellower) but it would still be getting 250W as far as I know. I don't know a whole lot about how ballasts work other than the basic fact that they alter the voltage and limit current to power the lamp.

This light is on all the time, it's connected to the overhead fixture, so when I turn the main light switch on the light is on. This light is mounted here to light the room, not for display. (Though it kind of is, but I put it up to light the room) So it's lit most of the time.
