Here's a picture of some odd robotic looking median lights seen on I-190 near Buffalo NY. They're highmast luminaires mounted on some sort of C shaped pole.
These fixtures are indeed made by Holophane. They are also present on I-95 where it runs through Westchester County, just north of the Bronx near Larchmont and Mamaroneck. They're mounted on the same style poles on the median so as to light both sides of the roadway.
There are similar fixtures in Ontario. I've also seen highmasts that was just a large cylinder and another where the ballasts were mounted off to the side.
FYI, these lights and the crook arms are being replaced with dual pipe mounts and GE LED fixtures. There is one stretch remaining to be done then I think the NYSDOT is going to concentrate on the exits.
BTW, I have a more recent and better pic here.
