Back before they actually started making HID grow ballast guys would just buy the kits(transformer,ignitor,capacitor, the guts inside those grow ballasts) and hang the transformers up with bailing wire from the rafters, run the wire through the holes in the corner of the transformer. Theres still old cats around here with the same shit setup. Brings back memories because we use to go to the scrap yard and buy the high bay lights that were being scraped and hard wire them. Then finally they started selling the pigtails or the BAASR and BAASP conversion plugs and that made it easy to rig up high bay lights. You can take the ignitor out of the loop for running halide bulbs on hps ballast by disconnecting the x3 wire between the transformer and ignitor or toggle switching it so it doesn't have that high voltage pulse. That pulse can be upwards of 5000volts and that damages the probe start halides. Dangerous, they will fire up but that pulse will cause premature failure and the bulb can explode. Nowadays most halide bulbs are pulse start for use with electronic ballast and old magnetic hps ballasts. You can tell this because the wire inside the outer envelope goes straight to the electrode in the arc tube, you dont have that little bi metal resistor switch or whatever it is.
