250w HPS lamp - like watching paint dry

This is a ballast for a 250 watt high pressure sodium lamp, that used to be in a streetlamp in the city of Phoenix. This unit had been mounted in an American Electric / ITT cobrahead luminare (in the video I mentioned Thompson Electric, this was incorrect) mounted on a light pole on 15th avenue north of Colter St. in Phoenix, AZ, but was brought down by a drywall truck that had swerved to avoid a dog in the road and wound up rolling over onto the light pole, bringing the light down on an early Sunday Morning, in late December of 1985. I got the ballast from the light head later on that morning and have had it since. In the ensuing 29 years, this ballast has had about 3 hours of use, sitting in storage from 1995 until today, when I pulled it out to see if it all still worked. I am happy to say it does. Not that it's ever going to be mounted in anything but it's still fun to play with. Watching these HID lamps come to full brightness is like watching paint dry.
