Westinghouse OV-25 400watt mercury vapor streetlight

This is my Westinghouse OV-25 400watt mercury vapor streetlight. This light came from an electrical utility manager in a small city near my parents home. My dad introduced me to him while he was designing a railroad spur in their community. The electrical utility manager showed me their fine collection of vintage lighting equipment. Then he let me pick some items out to have for my own, he gave me other items too, and explained what they were. The manager and me visited for over have an hour talking about lighting equipment. We will hopefully be seeing each other often. Anyway, this streetlight does not have a photocell socket so it does not have a photocell. This is 400watt mercury vapor and is 120volt.

@tpirman1982: Mine (this one) does not have a photocell socket on top either.

I have few of them and it's all hook up on 208 volts, whats the diagrams to transfer that to 120 volts.

Very nice! I have a couple of those in a 250W HPS flavour as well as several crouse-hinds "OVZ "series, one of witch is lowered to 50W HPS and at the end of the driveway.. I also have what I believe is a Holophane "bucket" streetlight in my yard that was 175W mercury, but was converted to 100W HPS by the utility when it was actually in service.
