I noticed a PG&E crew installing more lamp posts and swapping lamp housings on the ones that were four sided. I talked to one of the guys and he said, "Yup, this is it."Turns out the poles are not "cheesy", "they are cast aluminum!! They will probably be grouted around the base for a more finished look".
It was quite interesting watching the process. 
The bulb is a sodium vapor lamp. Because of its shape I think it is a High pressure sodium (HPS) lamp, according to this Wikipedia link.
The globe or housing has a reflector built inside the top that directs the light downward and reduces light pollution. I will blog a night photo once they are all installed.
